Abstract

A compact printed ultra‐wideband (UWB, 3.1–10.6 GHz) circular‐slot antenna with a notched frequency band at 5 GHz is presented. The antenna is a uniplanar structure and occupies a compact area of 25 × 26 mm^2^ only (the side length is less than 27% of the lower edge frequency at 3.1 GHz). The antenna has a U‐slotted circular stub embedded inside the circular slot. By choosing the length of the U‐slot cut in the circular stub to be about a half‐wavelength of the desired notched frequency, band‐notched UWB operation is obtained. © 2005 Wiley Periodicals, Inc.

## Abstract This paper presents the band‐notched operation of a printed short‐circuited wideband monopole antenna. The notched or rejected band within a wide operating bandwidth is obtained by embedding an inverted U‐shaped slot close to the shorting point of the antenna, where strong excited surfa
