发明名称 PLANAR CIRCULARLY POLARIZED ANTENNAS
摘要 A planar circularly polarized antenna comprises at least one coplanar waveguide feed line and a plurality of driven loops electrically connected to the feed line, wherein the driven loops and the feed line are substantially coplanar. At least one of the plurality of driven loops may be of a size different from at least another one of the plurality of driven loops and at least one of the plurality of driven loops may have a resonant frequency different from at least another one of the plurality of driven loops.
