Title:
BROADBAND CIRCULARLY-POLARIZED MILLIMETER WAVE MULTI-FEED MULTI-BEAM LENS ANTENNA
Document Type and Number:
WIPO Patent Application WO/2020/151074
Kind Code:
A1
Abstract:
Disclosed is a broadband circularly-polarized millimeter wave multi-feed multi-beam lens antenna. The antenna comprises one multi-port broadband circularly-polarized planar feed antenna array (1) and one planar lens (2); a plane of the multi-port broadband circularly-polarized planar feed antenna array (1) is provided parallel to the plane of the planar lens (2), and a signal of the multi-port broadband circularly-polarized planar feed antenna array (1) is output or received by means of the planar lens (2). The planar lens (2) has a plurality of phase-shifted distributed focal points which consist of completely identical anisotropic unit structures (5) in a periodic arrangement. The anisotropic unit structures (5) consist of an upper metal patch (5a), a middle metal patch (5b), and a lower metal patch (5c). The antenna can realize multi-feed multi-beam characteristics, and has wide application prospects in wireless communications and satellite communications.
