摘要：
In this paper, new wideband cavity backed aperture coupled microstrip antenna is presented for 79 GHz MIMO radar applications. This designs is based on a sub-arrays consisting of two single elements, which have stacked rectangular patch radiators. A microstrip to stripline transition and a series feeding topology is used to feed the elements. The antennas are manufactured by using a new high resolution multi-layer PCB technology. The performance of this antennas have been verified by both simulations and measurements. Antenna bandwidth is 9.7%, and the gain is more than 5.2dBi. Large beam widths of 138 degrees in E-plane and 40 degrees in H-plane are obtained. Antenna radiation efficiency is more than 75%, the mutual coupling between the array elements is less than -18dB.
