A novel UWB patch antenna with CPW fed

A novel ultra-wideband (UWB) coplanar patch antenna (CPA)with L-CPW fed is proposed with a wider impedance bandwidth than that of the conventional CPW fed patch antenna. A L-CPW was used to widen the bandwidth of the coplanar patch antenna. The antenna, operating at 7.7GHz was designed and fabricated. The results of return loss, radiation pattern and gain, both simulated and measured, were presented. A Good agreement between the simulation and measurement has been observed. The antenna has an impedance bandwidth at 10dB return loss about 17% and stable radiation patterns, which is suitable for the application of UWB.
