摘要：
P-shaped dual-band circularly polarized (CP) antenna for wireless communications with right-hand circular polarization (RHCP) and left-hand circular polarization (LHCP) is presented in this article. Optimized electrical volume of the proposed structure is 0.461 0 x 0.461 0 x 0.021 0 at 4.4 GHz resonant frequency. The measured-10 dB impedance bandwidths are 50.7% and 5.7% for (3.37-5.60 GHz) and (10.82-11.46 GHz) resonating bands at frequencies 4.4 GHz and 11.4 GHz respectively. The measured 3 dB impedance axial-ratio bandwidths for (4.65-5.13 GHz) and (11.21-11.52 GHz) bands are 9.7% and 2.7%. Agreement of simulation results with measured results ensure the excellent circular polarization at frequencies 4.96 GHz and 11.4 GHz.
