By employing the complementary dipole antenna concept to the normal waveguide fed slot radiator, an improved antenna element with wide impedance bandwidth and symmetrical radiation patterns is developed.

Circular Slot loaded ultrawideband circularly polarized Antenna | IEEE Conference Publication | IEEE Xplore

In this paper, a circular slot loaded circular monopole antenna for ultrawideband circularly polarized applications is presented. The antenna consists of a circular radiator fed by a modified feedline and multiple slots loaded modified coplanar waveguide (CPW) ground plane. The ground plane is also loaded with quarter elliptical slot and semicircular stub to achieve circular polarization. The overall dimensions of the proposed antenna are 17×20 mm2. The antenna has an impedance bandwidth of 4.41-14.0 GHz (104.2%) and axial ratio bandwidth (ARBW) of 5.87-13.66 GHz (79.77%). It has a peak gain of 5.34 dBi. The proposed antenna provides right hand circularly polarized (RHCP) radiation patterns along +z axis. It has advantages of compact dimensions, wide impedance bandwidth and wide axial ratio bandwidth over previously reported structures.
