Antenna Design, 3. D Electromagnetic Antenna Simulation Software. A patch antenna (also known as a rectangular microstrip antenna). A variant of the patch antenna commonly used in mobile phones is the shorted patch antenna.Antennas are essential wherever wireless communication required. They are the indispensable link between the contained signal and the “ether”. CST provides a variety of tools for each stage of the antenna design flow to study and improve your design. Antenna Magus is a software tool which allows the engineer to make an informed choice of an appropriate antenna element to suit their requirements, and produces validated designs which can be analysed further in CST MICROWAVE STUDIO. Antennas are used in a vast variety of applications, and thus take come in a vast variety of form factors and radiation mechanisms. The range of simulation methods in CST MWS allows the engineer to choose the best technique for each application. Microstrip Antenna Designs for. PowerPoint Presentation.

Microstrip Patch Antennas for Broadband Indoor Wireless Systems PROJECT. 3.0 FOUNDATIONS FOR MICROSTRIP DESIGN A microstrip patch antenna is a radiating. The most commonly employed microstrip antenna is a rectangular patch which looks like a truncated microstrip. Design of a Patch Antenna. The transient solver could be best for wideband or planar antennas, the frequency domain solver may be more suitable for electrically small antennas, while the integral equation solver can efficiently simulate electrically large or wire antennas. Installation of an antenna in a device or on a platform makes its analysis even more complex. The System Assembly and Modelling framework in CST DS allows the user to set up coupled simulations which can combine different solvers automatically by making use of field sources. Finally, powerful automated post- processing allows you to extract every magnitude of interest for an antenna designer – nearfield plots, SAR, phase center, directivity or farfield gain for single antennas or arrays - and to process those data further for use in parameter sweeps or optimizations in order to improve the performance of your design. Each system requires a functional antenna, since poor antenna performance may lead to a bad user experience in the form of low data throughput or poor coverage, and can cause calls to be dropped and car navigation to fail. On the other hand, devices must look appealing and their size must be minimized. The thinness of the devices and the presence of metallic structures have caused challenges to antenna design. Without 3. D simulations, there is a high risk of having poor antenna performance or clumsy industrial design. The alternative for antenna verifi cation is to use multiple prototyping rounds, which are expensive and have a long lead time. However, there are things that cannot be effectively studied with prototypes, for example grounding structures and impedance matching networks. We have seen a corresponding increase in the implementation of all kinds of technologies in the car for entertainment, utility, and safety. A typical high- end car today has AM, FM, DAB and GSM satellite radio, tire- pressure monitoring (TPM), remote entry and start, in- vehicle TV, GPS navigation, Bluetooth, electronic toll collection, and multiple radar systems (e. To meet these needs, research and development regarding fifth generation (5. G) antennas is already underway. This webinar shows the workflow and simulation features in CST STUDIO SUITE that are enabling antenna engineers to envision and design the next generation of mobile device antennas. Compact, smart antenna array concepts provide the necessary data performance, but pose a unique challenge for antenna designers. The aim of the mission is to send two orbiters to Mercury in order to study its atmosphere, composition and magnetic field to help understand how the planet was formed, as well as to verify some key predictions of general relativity. Airbus Defence and Space (Airbus DS) is the prime contractor for the ESA elements of the mission, including the Mercury Planetary Orbiter (MPO). The MPO includes multiple antenna systems . In order to ensure that the MPO functions as expected when it reaches Mercury. Yet, ironically, it makes an excellent broadband antenna. Design parameters and tradeoffs are presented for microstrip antennas. All of the parameters in a rectangular patch antenna design. To avoid confusion, antennas based on this approach are called leaky feeders. They are typically used in environments that mirror the cylindrical shape and length of the cable: tunnels, mines, aircraft, railroad tracks and skyscrapers. CST provides a tutorial explaining the basic theory and electromagnetic performance. Turning theory into practice, with assistance from W. Gore, we examine their use enabling Wi- Fi and cellular service on commercial airlines and corporate jets. For effects that cannot be accounted for analytically such as edge effects and mutual coupling, full- wave 3. D simulation can complement synthesis tools and allow designs to be checked and fine tuned. This article explores the synthesis of an antenna array, using a phased array satellite communications antenna as an example. Sie sind leicht, robust und bieten einen hohen Gewinn und eine sehr gute Richtcharakteristik. Dabei sind sie relativ einfach herzustellen. SWAs bestehen aus einem Hohlleiter, dessen Wand durch Schlitze unterbrochen ist. The first part is a review of low frequency power transfer in two categories: short range- inductive charging and powering of electronic devices and electric vehicles, and mid- range power transfer through coupled resonant circuits. We will give several examples and highlight the role of simulation in the design of transfer systems. The tools in CST STUDIO SUITE. We make a distinction between harvesting RF energy from signals present in the ambient and transferring RF energy by intentionally transmitting RF signals. After a discussion of the power densities, we will continue with (intentional) RF energy transfer for powering sensors to be used in Smart Buildings. The blocks of a far field RF energy transfer system will be discussed: Transmit antenna (and maximum allowed transmit power), propagation channel and rectifying antenna or rectenna. The components of the rectenna: rectifier, dc- dc boost converter and antenna, will then be discussed. Several examples will be shown. Although a fast analysis can be based on S- parameters, this approach has limitations. A more detailed analysis needs to take into account broadband, farfield and antenna properties. These are especially important in presence of the human body. This webinar will show how simulation can be used to calculate the effect of hand and head (e. CTIA models) on mobile devices, MIMO for wearable antennas and different power weighting functions for different environments, along with post- processing options for envelope correlation (including spatial power weighting functions), derived quantities diversity gain and multiplexing efficiency. Finally, there will be a demonstration of the link between CST MICROWAVE STUDIO. However, this is only possible when the EM simulator is given the correct input data that accurately represents the physical device. Then an excellent agreement between simulation and measurement can be expected. There are many possible causes of discrepancies between the two, including geometric differences (over- etching, over- milling, rounded corners), material properties (anisotropic dielectrics, surface roughness), installed performance (surrounding structures) and feed discrepancies (connector modeling). This webinar will explore the relationship between simulation, using CST STUDIO SUITE. In some situations measurement can be difficult to perform while simulation is simpler, and vice versa. Simulation allows many variations on a design to be investigated, using techniques such as parameter sweeps, sensitivity and yield analysis. The webinar will also demonstrate how simulation can be used for what- if analysis and feasibility studies at early stage of design before first prototypes. Finally, the use of measured data to calibrate simulation will be shown. This is useful for hard- to- model phenomena like surface roughness or for the modeling of low- cost adapters. The exotic properties of these metamaterials include negative or low values of permittivity, permeability and refractive index, allowing engineers to manipulate the material. The metamaterial- based waveguide structures, such as composite right/left- handed (CRLH) structures, have led to interesting applications of waveguide miniaturization and novel coupler design. Metamaterial- inspired antenna design has produced reflex- cavity antennas with low- profile, high gain, beam steering and frequency agility. Although major satellite operators have already begun deploying next- generation satellites with high data throughputs, accessing these currently requires bulky, expensive equipment with high power requirements for the user. Unlocking the full potential of these data links requires an antenna solution that can track satellites while also being portable enough to attach to a vehicle or take into the field. The antenna is designed to be driven by a high- power, single- shot signal generator with 1 ns pulse- width at the - 3 d. B power points, and peak voltage of up to 1. V. Since the signal generator is equipped with an air- filled coaxial- waveguide output, a coaxial- waveguide to parallel- plates transition was also designed and fabricated. Initial theoretical electrical parameters and characteristics along with physical dimensions of the system were solved and derived using MATLAB. Then, the components comprising the antenna were modeled, solved and optimized using CST STUDIO SUITE. Using the CAD export capabilities in CST STUDIO SUITE, fabrication models and schematics were produced from the simulation model. The antenna was fabricated and measured results agree with simulation results to a great extent. The goal in this case is to design an array with high directivity, low cost and low sidelobes, exhibiting a good impedance matching in the frequency range 5. The same approach can also be used to design other types of array by using a different radiator or array layout. The requirement was to replace an existing . The new antenna had to operate inside the standard GSM 9. PCB. The new integrated antenna was designed using Antenna Magus in combination with CST MWS to account for unwanted coupling, ensuring that the antenna operated within the desired frequency bands.
