Abstract: Wider bandwidth microstrip antenna employing resonant slot require substrate thickness in excess of 0.07λg, which increases the antenna volume. In this paper, a novel technique to increase the bandwidth in E-shape microstrip antenna fabricated on a thinner microwave substrate, while employing printed resonator elements is proposed. The printed resonator positioned below the patch, introduces TM20 mode nearer to the TM10 mode in E-shape antenna that increases the bandwidth. On substrate thickness of 0.037λg, optimum design achieves bandwidth of 130 MHz (13.89%), with a broadside radiation pattern and peak gain of 7.8 dBi. With the obtained antenna characteristics, proposed thinner substrate designs will find applications in GSM band.
