| Summary: | A new compact coplanar waveguide (CPW) -fed broadband circularly polarized (CP) monopole antenna is proposed in this study. The antenna structure is composed of an L-shaped monopole, an asymmetric
modified ground plane and a couple series-aligning inverted L-shaped strip. The modification of cutting two slots in the asymmetric ground plane achieves a wide CP bandwidth, and a couple series-aligning inverted L-shaped strip is introduced with the left ground plane to achieve broadband impedance bandwidth (IBW). A - 10 dB IBW of 103% (2–6.2 GHz) and 3 dB axial ratio bandwidth (ARBW) of 98% (1.9– 5.85 GHz) is achieved. The antenna design process and the parametric study are presented, and the CP mechanism is analyzed. |
