摘要
Abstract
Aiming at the millimeter wave band,a 77 GHz anti-collision radar antenna is designed by using three-dimensional electromagnetic simulation software COMSOL Multiphysics.The proposed antenna uses the series-parallel feed network,achieving the higher gain and lower sidelobed level by forming the array.The simulation results show that the operating frequency band of the 77 GHz anti-collision radar antenna covers 76.35～77.76 GHz.Under the premise of achieving high gain of 22.2 dBi,the sidelobe level is kept 15 dB lower than the main lobe level,and the beamwidth is 9.57°×20.2°.The antenna basically meets the design requirements of vehicle radar antenna for high gain and low sidelobe level.关键词
