Abstract

In this paper, we present a compact thin-film ultrawideband (UWB) antenna with round corner rectangular slot and partial circular patch. A CPW-fed rectangular slot with a fork-like tuning stub radiates through a rectangular aperture, which ensures UWB impedance matching from 2 GHz to 11.6 GHz for S₁₁ <; -10 dB. This antenna is printed on Mylar® Polyester Film substrate with size of 60 × 53.3 mm² and thickness of 0.3 mm. The return loss, current distributions, and radiation patterns of the fabricated antennas are presented. The antenna is determined using design equation, and simulated the commercial IE3D software, which is based on the method of moments, and is verified experimentally. The results show that proposed antenna is very suitable for various portable UWB applications.
