A Planar V-Band Antenna for Wideband Radar and Communication on Low-Cost PCB Substrate

Abstract

A rectangular microstrip antenna with a resonant frequency of 60.5 GHz and a bandwidth of 4 GHz is proposed and evaluated. The antenna is based on the low-cost substrate RO4350B and is designed to reduce costs for prototypes and small batch series by complying with design restrictions for inexpensive pooling offers by many manufacturers. The influence of manufacturing tolerances on the performance of the antenna is also investigated and minimized. Finally, an antenna is fabricated and measurements are compared with simulations.
