WIDE-SCAN-CAPABLE POLARIZATION-DIVERSE POLARIZER WITH ENHANCED SWITCHABLE DUAL-POLARIZATION PROPERTIES

摘要

A dual-mode polarizer (11) for selectively switching between linear polarization (26) and circular polarization (23) includes a first meander-line polarizer (12), and a second meander-line polarizer (14) spaced apart from the first meander-line polarizer (12) to define a first gap (16) therebetween. A first angular orientation between the first and second meander-line polarizers (12, 14) produces variably-oriented linear polarization of a signal passing through the first and second meander-line polarizers (12, 14), and a second angular orientation between the first and second meander-line polarizers (12, 14) produces variably-oriented circular polarization of a signal passing through the first and second meander-line polarizers (12, 14).
