Abstract

In this paper, we propose a small, lightweight, and low‐cost ultra‐wideband (UWB) antenna that exhibits a notch characteristic in the 5‐GHz WLAN band (5.15–5.825 GHz) using a planar half‐circle shape patch, a two‐step matching stub, a coplanar waveguide (CPW)‐type feed, and a hat‐shaped slot. The notch frequency of the proposed antenna can be adjusted by controlling the slot length. The measured results are in reasonably good agreement with the simulated results. © 2005 Wiley Periodicals, Inc.

In this paper, we propose a frequency-notched ultrawideband (UWB) slot antenna. The proposed antenna can cover the entire UWB band and the IEEE 802.11a frequency band can be notched out by inserting a hat-shaped slot into the antenna. The path loss ͉S 21 ͉ and group delay are measured and discussed.

## Abstract In this article, a novel ultra‐wideband (UWB) antenna with band‐stop characteristic is proposed. The UWB characteristic of the proposed antenna is achieved by adopting two spiral elements. By attaching two L‐shaped stubs along the microstrip feed line, the band‐stop performance can be a

## Abstract A compact microstrip band‐selective filter for ultra‐wideband (3.1–10.6 GHz) radio system is proposed. The filter combines an optimum pseudo‐bandpass filter and a coupled resonator bandstop filter on both sides of the meandered 50‐Ω microstrip line. Three coupled resonators are modified
