摘要：
A monopole antenna with coplanar-waveguide (CPW)-feeding structure has been developed in this study for multiple wireless communication system integration. A right-hand circularly polarized (RHCP) radiating wave at 1.57 GHz and a left-hand circularly polarized (LHCP) radiating wave at 2.33 GHz are generated for the global positioning system (GPS) and the satellite digital audio radio (SDAR) service system by utilizing bent feeding topology, asymmetric ground plane, and an L-shaped slot etched in the ground plane, The experimental impedance bandwidths range from 1.40 to 2.98 GHz and from 4.48 to 6.27 GHz. The experimental 3-dB axial ratio (AR) bandwidths are 80 MHz at 1.57 GHz and 100 MHz at 2.33 GHz.
