CST – Computer Simulation Technology

Design and Optimization of a 24 GHz RF Module Using VBA

VBA programming was used to create a fully parametrized design in CST MICROWAVE STUDIO® (CST MWS) of a RF module containing matching circuits and antenna for a RF module to be used in a game controller. The complete module was modeled in CST MWS and the design trade-offs were investigated by varying different parameters. Using this VBA program it became easy to create different designs and optimize interesting parameters for board size and performance. The design was fabricated and found to behave according to the simulation results, no second spin was needed. The design will be used in mass production.
