Abstract

This paper presents a new coplanar waveguide-fed (CPW-fed) Ultra-Wideband antenna design suitable for wireless terminal devices. Specifically, it consists of a modified radiation patch with a circular-ring schematic arranged in a single layer, as well as a half-oval-shaped ground plane. The patch is fed with a coplanar waveguide (CPW) feeder. This configuration is implemented using FR- 4 substrate material, which possesses a tangent loss of 0.02 and a dielectric constant of 4.4, with a thickness of 1.6 mm. This antenna is designed to operate in the frequency range of 2.3 - 18 GHz. The simulated results and relevant measures show a satisfactory degree of agreement. The performance of the proposed structure is compared to similar techniques available in the literature and it is found that it has superior performance regarding the ultra-wideband span as well as the fractional bandwidth. It has a comparable performance regarding gain and efficiency.
