Antenna Simulation

In antenna development, the challenge usually lies in spatial limitations and available shoring locations. In the course of feasibility studies or installation space optimization, simulations are often used to achieve a cost-saving indication of the possible variants. Existing antenna models can be used and optimized for new series. Subsequently, the simulation model is verified in the measurement chamber using manufactured prototypes.

Whether PIFA, patch or monocone antenna with CST we are free in the design. Which antenna fits into the defined installation space while meeting desired requirements? – With a simulation model, both in free space and in a defined installation space, you get an overview of radiation characteristics in far field. We can examine existing antenna models from your portfolio in a new environment or start a new development. In doing so, we focus entirely on your needs.

Through our technical measurement expertise in automotive industry, we have built up a broad experience of various antenna applications. Simulation models according to your requirements can be produced, for example, in planar form using our mill-drill plotter. Whether BLE, V2X, LTE, Wifi or 5G, manufactured prototypes can be verified according to all common standards in our test site.  We accompany you from definition or classification of requirement specification to research on possible antenna types and the first simulation model. If simulation results meet the requirements, we can have prototypes manufactured and analyze them metrologically. Subsequently, simulation and measurement results are verified. Thus, the simulation model can be further optimized and tolerances can be determined.

Figure 1 shows a simulation model of a PIFA, where only the “T”, in connection with the ground plane, is the radiating element at 2.4 GHz. This can be used for Wifi and BLE. The ground plane makes the antenna much smaller vertically than a comparable monopole. The associated radiation pattern is shown in Figure 2 (directivity in dBi). The antenna radiates omni-directionally in phi plane and most of power is emitted in theta range of 10° to 40° (ground plane: theta = 0°). Thus, the PIFA is well suited to spread Wifi horizontally over a wide area.
