摘要
In this paper, a new design of dual band-notch printed monopole antenna for UWB applications is proposed. The antenna consists of a circular disc radiating patch with a protruded anchor-shaped strip, a feed line with an inverted U-ring slot and a ground plane structure, which provides a wide usable fractional bandwidth of more than 125% (2.69-12.53 GHz) with dual band-stop performance around of 3.3-4.2 GHz and 5-6 GHz. In the proposed structure, by using a protruded anchor-shaped strip in the radiating patch, a single frequency band-stop performance can be achieved. Also, in order to create the second notched frequency, an inverted U-ring slot was cut at the feed line. Simulated and measured results obtained for this antenna show that the proposed monopole antenna offers two notched bands, covering all the 5.2/5.8 GHz WLAN, 3.5/5.5 GHz WiMAX and 4-GHz C-band range. The proposed antenna has a small dimension of 12x18x1.6 mm(3).
