摘要：

A regular-hexagonal structure of wide-slot antenna for broadband circular polarization (CP) based on coplanar waveguide (CPW) feed is presented. By protruding into the slot an L-shape monopole patch, and featuring two inverted-L grounded strips around two opposite sides of the slot, wide impedance bandwidth and wide axial-ratio (AR) bandwidth can be obtained simultaneously. By notching a rectangle in the ground conductor near the feed line, the antenna performance is further improved. The proposed antenna can provide an impedance bandwidth (S-11 < -10 dB) of 86% and a 3-dB AR bandwidth of 50%, respectively.
