Title:
BROADBAND POLARIZATION TWISTER AND POLARIZATION TWISTING DUAL-REFLECTOR ANTENNA USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/056047
Kind Code:
A3
Abstract:
Disclosed is a broadband polarization twisting technique. According to one embodiment of the present invention, the broadband polarization twister comprises a conducting plate that performs a polarization twisting process, wherein meander grooves are formed on a reflecting surface of the conducting plate. Thus, the invention improves broadband polarization twisting performance, and minimizes polarization twisting loss.
