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 ... soya77 slot
