A New Triple Band Circularly Polarized Square Slot Antenna Design with Crooked T and F-Shape Strips for Wireless Applications

A new design for Circularly Polarized Square Slot Antenna (CPSSA) is presented. The circular polarization operation in the proposed single-layer antenna is created through two equal sized crooked T-shape and an F-shape strips located on the patch. Compared to most of the previously reported CPSSA structures, the impedance bandwidth and the axial ratio bandwidth of the antenna are increased and also the size of the antenna becomes smaller. The presented CPSSA design has the compact dimensions of 40x40x0.8mm3, total impedance matching bandwidth of 8.04GHz and exhibiting a 28.03% (4.6-6.1GHz) 3dB axial ratio bandwidth.
