Abstract
In this paper, a compact monopole wideband antenna is designed and manufactured for ultra-wide band (UWB) applications. In order to extend the impedance bandwidth of the proposed antenna, rectangular and triangular slots are etched from the partial ground and from the center of the rectangular patch respectively. Also, by cutting the lower corners of the radiating patch using stepped technique, additional resonances are regenerated and lead to further improvement in the covered bandwidth. The proposed patch antenna has advantageous of compactness its overall size equals 40 × 40 mm2.Simulated and measured results show that the proposed antenna design exhibits a bandwidth from 2.9 – 19.2 GHz for VSWR< 2. The antenna structure provides a wide usable fractional bandwidth of 148%. These inherent characteristics of the proposed antenna make it suitable for efficient transmission and reception in UWB systems. © 2016 Wiley Periodicals, Inc.
