Abstract

Two printed wide-slot antennas with E-shaped patches and slots for broadband applications are proposed They are fed by a coplanar waveguide CPW and a microstrip line with almost the same performances Detailed simulation and experimental investigations are conducted to understand their behavior and optimize for broadband operation Good agreement between the measurement and simulation has been achieved The impedance bandwidths determined by 10-dB reflection coefficient of the proposed slot antennas fed by microstrip line and CPW are examined from both measurement and simulation We have obtained the large operating bandwidth by choosing suitable combinations of feed and slot shapes In order to achieve wider operation bandwidth both of the designed antennas have round corners on the wide slot and patch Meanwhile the proposed antennas exhibit almost omnidirectional radiation patterns relatively high gain and low cross polarization A comprehensive numerical sensitivity analysis has been done to understand the effects of various dimensional parameters and to optimize the performance of the designed antennas Results for reflection coefficient far-field E and H-plane radiation patterns and gain of the designed antennas are presented and discussed At the end we compare the simulated and measured results and found the enhancement of bandwidth of E- shape microstrip antenna
