Modified E-H shaped microstrip patch antenna

A wideband L-probe fed microstrip patch antenna is proposed. By employing L-shaped feed and modification of E-H shaped patch, an antenna with 30% impedance bandwidth (return loss -10dB) and a gain of 9.41dBi is achieved. It is shown that the wide bandwidth is caused by a two-frequency resonance. The achievable experimental 3-dB beamwidth in the azimuth and elevation are 63.53° and 51.37° respectively at the center frequency.
