Summary:
A single-layer antenna composed of four subarrays and compact low-loss feed-line structures connecting to an RF-module for 77 GHz automotive radar systems is presented. This antenna is based on a slotted post-wall waveguide array, which is integrated in a ceramic-filled PTFE substrate. The antenna gain is higher than 16 dBi relative to the maximum available directivity of 20.4 dBi at 76.5 GHz. The proposed compact feed-line structures achieve the low transmission loss of less than 3.2 dB.
