N2 - Luneburg lens antenna (LLA) has excellent multi-beam characteristics of high gain and low sidelobe level (SLL), but large volume limits its application in practical scenes. Existing efforts of size reduction often suffered deteriorated beam coverage. To overcome this problem, a compact ellipsoidal Luneburg lens antenna (ELLA) fed by a parallel non-uniform squint waveguide array is proposed. The design of the feed and reflector can effectively optimize gain and regulate SLL of the margin beam. Working in frequency bands in 26-35 GHz, the proposed ELL antenna with compression rate of 0.5 achieves gain of 21.22 dBi at 30.5 GHz, and can provide beam coverage up to ±57°. © 2024 IEEE.
