Broadband Circularly Polarized Filtering Monopole Antenna for C-Band Applications
A simple and compact broadband circularly polarized (CP) filtering planar monopole antenna for C-band applications is presented. A printed falcate-shaped monopole with a modified ground plane is applied to realize broadband impedance matching and circular polarization radiation. By symmetrically etching a pair of rectangular complementary split-ring resonators (CSRRs) on the ground plane directly beneath the feedline, good filtering performance in the upper stopband is achieved and CP radiation towards high frequency is enhanced. The proposed antenna provides −10 dB impedance bandwidth of 72% ranging from 3.8 to 8.1 GHz, and the 3 dB axial ratio (AR) bandwidth of 63% ranging from 4.1-7.9 GHz.
