A novel dual frequency notched UWB antenna with dual L-shape slots

摘要

A planar UWB monopole antenna with double notch frequency bands is presented. The proposed antenna consists of a planar monopole antenna and two L-shape slots which are used to generate two notch frequency bands. The bandwidth of the antenna is from 2.5 to 10.75GHz, while the proposed antenna has two notch bands of 3.35–3.75GHz and 4.85–6.1GHz, which cover 3.5GHz WIMAX band from 3.4GHz to 3.69GHz and 5.5 GHz WLAN band from 5.15GHz to 5.825GHz, respectively. The parameters determining the antenna's band notched characteristic are discussed.
