Highly Integrated Q/V-Band Multi-Beam Phased Array Antenna for LEO Communication Satellite

Abstract

This paper presents two design approaches of a satellite-borne Q/V-band multi-beam phased array antenna. By analyzing the challenges of antenna design in millimeter-wave (mm-Wave) satellite communication, an eight-beam integrated subarray antenna is proposed by hybrid brick-tile and tile constructions based on the multi-beam beamformer chip using silicon technology. By simulation and comparison, the tile-construction array design is employed for the large-scale antenna design by advantages of low-profile and flexibility of subarray arrangement. At last, a large-scale array design for satellite-borne application is provided.
