摘要: In this letter, a compact three-dimensional (3-D) null steering antenna is presented for circular polarization. Two high-isolated circularly polarized (CP) pattern modes, the broadside and conical CP are synthesized 3-D in upper hemisphere. The mode generated by corner-truncated patch, four rotationally symmetric strips. By controlling exciting power ratio relative phase delay of two continuous achieved elevation plane azimuth plane, respectively. A prototype proposed operating at 1.575 GHz fabricated tested global position system (GPS) applications. simulated measured results verify performance design.
