Abstract

This article submits a bandwidth enhancing technique using E-shape slot and 3 notches on the bottom corners of the patch for an antenna with micro strip line. The proposed small size antenna on 20 mm × 20 mm printed on substrate type (FR-4) is designed and confirmed through simulations. Reception apparatus parameters are moldered and introduced utilizing programming CST. The results show that at frequency 8 GHz the return loss value is -18.08 dB with VSWR 1.29; at frequency 10.04 GHz the return loss value is -45.9 dB with VSWR 1.03. The bandwidth of the proposed antenna is 3.1 GHz or about 34.33% at VSWR < 2, which can therefore be classified as UWB antenna.

Keywords: Ultra-wide band, slotted antenna, bandwidth enhancement.
