摘要
A new broadband circularly polarized (CP) square slot antenna with coplanar waveguide fed is proposed. Two symmetrical E-shaped slits embedded in opposite corners of ground plane are designed to obtain an excellent CP bandwidth. Simulated results show that the broadband performance is formed by three resonant modes. Some key parameters are studied to analysis the characteristics of the proposed antenna. Measured results show, that the 3 dB axial ratio bandwidth is larger than 32.8% relative to the center frequency of 2165 MHz and the impedance bandwidth is as large as 54.8% with voltage standing wave ratio (VSWR) <= 2.
