MEANDER LINE CIRCULAR POLARISER

摘要

A wideband meander-line circular polariser includes a substrate and a plurality of parallel meander shaped conductors (meander lines). Each parallel meander line (20,30) is loaded with electrically isolated capacitive elements (40) enclosed within some or all of the individual meander loops, allowing the polariser to be made electrically smaller for a given wavelength whilst maintaining the desired resonant frequency. Multiple layers of the device ma be used.
