摘要
In this paper, a printed elliptical monopole antenna for wideband circular polarization is proposed. The antenna's structure is asymmetric with regard to the microstrip line. The section of the ground plane that overlaps the elliptical patch is removed. With simulations, the relationship between the antenna's geometrical parameters and the antenna's axial ratio of circularly polarized wave is clarified. The operational principle for wideband circular polarization is explained by the simulated electric current distributions. The simulated and measured bandwidths of the 3 dB axial ratio with a 2-VSWR is approximately 88.40% (2.12 GHz-5.47 GHz) and 83.6% (2.20 GHz-5.36 GHz), respectively.
