Abstract :
A new single-feed technique for high gain operation of the circularly polarized cross-slot antenna backed by a ground reflector is presented. The antenna, which has a size of one wavelength, exhibits a gain of 11 dBi over a 3 dB axial ratio bandwidth of 5%. Simulations are performed using an EM simulator IE3D and agree well with experimental results.
