Abstract
- Summary: In this paper, a modified bow tie‐shaped antenna for ultra‐wideband (UWB) communication applications is presented. The anticipated antenna consists of a CPW‐fed modified bow tie‐shaped patch and two asymmetric ground planes with dual parasitic elements. Electromagnetic computation on the antenna demonstrates that the patch and grounds are strongly linked, and the designed antenna can exhibit multiple resonances which overlap to reveal the UWB working spectrum. Experimental verification of the presented antenna shows that the antenna achieved a working band of 3.2–11.0 GHz, with a fractional bandwidth of 109.9%. The antenna also attained a peak gain of 4.32 dBi at 7.3 GHz and peak efficiency of 87.3% at 6.8 GHz and reveals excellent time‐domain behavior and omnidirectional radiation patterns throughout the operating band. A small‐size, large operating band, high gain and efficiency, high fidelity factor, omnidirectional radiation patterns, and very small group delay make the antenna ideal for portable communication devices in the UWB band.
