“…Hence they achieve higher gain and higher aperture and radiation efficiency. The ACSP antenna presented in this work, however surpasses the designs in [7] for all the mentioned criteria. An important reason for the difference is the compact feed network implemented, including the novel sub-array power divider.…”

A hybrid thin film multilayer antenna for automotive radar is presented in this work. A 2 × 8 aperture coupled stacked patch antenna array is realized on a single layer printed circuit board (PCB) using a novel thin film-based approach. Using a compact 180° phase difference power divider, inter-element spacing in a 2×2 sub-array is reduced. Measurement results show a 19% (67.9–82.5 GHz) impedance bandwidth and a wideband broadside radiation pattern, with a maximum gain of 15.4 dBi realized gain at 72 GHz. The presented antenna compares favorably with other multilayer PCB antennas in terms of performance, with the advantage of simpler manufacturing and robust design. The antenna can be employed in mid-range automotive radar applications.

“…is low, which is the result of the high losses of the applied LTCC materials. In Ref., hybrid multi‐layer grid arrays are presented to reduce the cost, but they only have a 40° beam width in azimuth, which is very limited for medium and short range automotive radars. Further, they have very high SLLs at the band edge frequencies (77 and 81 GHz), and huge losses along the feeding network.…”

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.
