Broadband Reactively Coupled E-Shaped Microstrip Antennas

The broadband microstrip antennas are realized by cutting the resonant slots of quarter wave in length on the edges of the patch or half wave in length inside the patch. The broadband E-shaped microstrip antenna is realized by cutting the pair of nearly quarter wavelength slots on one of the radiating edges of the rectangular microstrip antenna. In this paper, a new broadband configuration of E-shaped microstrip antenna, by reactively feeding it using coupling rectangular strip, is proposed. The proposed configuration gives bandwidth of more than 300 MHz (> 35%) with broadside radiation pattern and gain of more than 7 dBi over the entire bandwidth.
