摘要
A new circular polarization planar printed monopole antenna with broadband characteristics in both axial and impedance is proposed and experimentally studied. By inserting a vertical slot into the left ground plane and cutting a horizontal slit in the right ground plane, the impedance bandwidth of the antenna is enlarged, and its wide axial ratio bandwidth is achieved. The measured results show a -10-dB S11 bandwidth of 69.6% from 3.60 to 7.47 GHz and a 3-dB axial ratio bandwidth of 27.9% from 4.72 to 6.25 GHz. The radiations of antenna exhibit a right-hand circular polarization in the +z direction and a left-hand circular polarization in the opposite direction. Moreover, a parametric study of the design is carried out.
