Design of a low-cost W-band wide-angle scanning phased-array radar antenna

Abstract： This paper presents a low-cost W-band radar antenna array based on PCB technology by employing a substrate integrated waveguide structure. The proposed array consists of eight antenna elements, each of which incorporates four waveguide radiating apertures. The four radiating apertures are connected through a longitudinal one-to-four substrate integrated waveguid power divider and are directly fed by the chip via a waveguide-to-stripline-to-grounded coplanar waveguide transition. Experimental results show that the operating bandwidth of the array ranges from 92.8 to 95.0 GHz. Moreover, the array is capable of achieving one-dimensional wide-angle scanning over ±30° while maintaining favorable radiation patterns, demonstrating excellent wide-angle and broadband scanning performance.
