Dual Frequency Wide Band Cusp Antenna Fed by Coplanar Waveguide

In this paper, a dual frequency wide band cusp antenna is for the first time introduced. The antenna is designed to operate in both X- and Ku- bands around 9.66 GHz and 14.83 GHz, respectively. The proposed antenna has been analyzed both theoretically and experimentally. The return loss and the radiation patterns are presented and discussed. The cusp antenna has a wide band behavior around both operating frequencies. It has a dipole like radiation pattern which makes it suitable for phased arrays.
