Haitham Alsaif, N. E. Islam
The design analysis andfabrication of an antenna with improved gain and operational beyond the conventional ultra wideband frequency range is presented. The proposed antenna provides extremely wide operating frequency bandwidth, from 2.9 GHz till more than 18 GHz, with a maximum gain of 6.8dB, which is appropriate for ultra wideband wireless applications. The patch is printed on FR4 substrate with permittivity of�r=4.3 and the antenna is simple in design and easy in fabrication. The simulation results and the experimental measurements show that the antenna gain is excellent during the operating frequency.
