A New Compact Circular Polarized CPW Antenna Design for UWB Application

A New Compact Circular Polarized CPW Antenna Design for UWB Application

Current paper proposes a new Coplanar waveguide (CPW) feed antenna for UWB application. The suggested antenna consists of a circular patch with two circular slots and a semicircular gap on the feedline with two rectangular shapes as ground in 2.6 x 30 x1.6mm3 dimensions with spiral and semicircular slots on it. In this outline, the impedance bandwidth (S11) has increased to a significate number together with the axial ratio bandwidth (ARBW), 123 % (3.3 GHz - 13.9 GHz). The article presents the designing steps of the antenna.
