Abstract

A novel slot antenna of large bandwidth and small size, which is fed by a fan‐shaped microstrip feed with a straight stub, is introduced. The effect of the fan feed on the impedance characteristics is investigated theoretically and experimentally. Good agreement between the theoretical and experimental results is obtained. Its measured VSWR ≤ 2 bandwidth reaches approximately 114%, covering 1.55–5.66 GHz. The measured standing‐wave ratio curves and radiation patterns of the antenna at f = 2 GHz and at f = 5 GHz are both presented. © 2005 Wiley Periodicals, Inc.

## Abstract A novel ultra‐wideband wide‐slot antenna fed with a microstrip‐line is presented. The antenna is composed of a circular microstrip patch and a semicircular arc cut on the ground of the microstrip line. The measured results show that the proposed antenna has an impedance bandwidth of mor
