Abstract

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 inCST MICROWAVE STUDIO (CST MWS). 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. 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. Antennas never operate in isolation, but are attached to a feed network. CST DESIGN STUDIO (CST DS) allows the hybrid co-simulation of the effect of an attached circuit on the antenna performance. 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. The usual aim of electromagnetic simulation in design is to lower the number of prototypes to reduce costs and time to market. 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®, and measurement, and explain what each domain is best suited for. 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 ® ™
