A parasitic patch antenna array based on a new multi‐layer PCB technology, called the Any‐Layer PCB technology, is presented. The antenna is designed for 77‐81 GHz MIMO radar systems, mainly for automotive applications. The designed antenna array is composed of 4 sub‐arrays. Each sub‐array is based on 2 parasitic patches which are excited by a feeding patch. With this feeding topology, the radiation pattern and gain of the proposed antenna are nearly constant across the whole 4 GHz bandwidth, which is a very attractive feature for radar designers. A prototype has been fabricated and measured. The gain and SLL are 10.22, and ‐14.11 dB at 79 GHz, respectively.
