Abstract

The design and analysis of printed antenna with the reduced ground plane effect, fed by micro strip line for Ultra Wide Band (UWB) communication systems is presented. The simulated results indicate that by cutting an elliptical patch at radiator, the proposed antenna yields a wide operating bandwidth of 2.1-13.8 GHz for -10dB return loss. In particular, the ground-plane effect on impedance performance is greatly reduced by cutting the patch from the radiator because the electric currents on the ground plane are significantly suppressed at the lower edge operating frequencies. In addition to being small in size of 15mm × 15mm, the antenna presents three-dimensional omni directional radiation across the entire UWB bandwidth with high gain. The proposed antenna has satisfactory band notched characteristics with the peak value of the VSWR in the stop band is 8.
