Abstract

A method to increase the bandwidth of planar monopoles is presented. Following the provided design criteria, a simple rectangular‐shaped monopole is fit to operate at ultra‐wide‐band (UWB) frequency. The process involves two steps: (i) optimizing the perimeter and feeding dimensions and (ii) conducting a suitable slot. This causes the difference between the upper and lower frequency limits to nearly double. The exhibited bandwidth ratio is 1:3.75. The measured radiation patterns are presented and observed to be stable. © 2005 Wiley Periodicals, Inc.

## Abstract A new design about planar triangular monopole antenna using a modified ground plane for bandwidth enhancement is proposed. By symmetrically etching a pair of modified L‐shaped slots in the ground plane, the impendence bandwidth is increased to 2.5–10.8 GHz under the condition of VSWR<2.

## Abstract In this article, we propose a swallow‐tailed UWB planar monopole antenna that exhibits a notch characteristic in the 5‐GHz WLAN band (5.15–5.825 GHz) by inserting a hat‐shaped slot into the antenna. The effects of the length of the slot on the notched frequency band are analyzed. The ra

## Abstract A new, low‐profile planar circular disc‐and‐ring monopole antenna is proposed for dual‐band and ultra‐wideband (UWB) operations. The first band is specified for the universal mobile telecommunication system (UMTS, 1.92–2.17 GHz) and the second is for the FCC‐defined UWB system (3.1–10.6
