Design of radar antenna based on HFSS

摘要

In this paper, a millimeter-wave radar array antenna with practical application is designed. According to the requirements of practical application of the speed radar, the actual detection range and return loss characteristics of the radar antenna are very demanding. At this request, the radar antenna array arrangement, through the power distributor to allocate the current of the single-patch antenna, and through the application of U shaped slot change the return loss, the application of HFSS software simulation analysis of the parameters of the antenna. At the same time the application of a variety of equipment testing and the actual road vehicle speed test, to meet the design requirements of the microstrip array antenna.
