Abstract

In this paper a new UWB antenna is proposed which is a printed slot antenna feeding by a 50 ohm CPW line via a circular microstrip patch. This antenna has a parasitic curve slot etched on the circular patch which makes a notch between 5 GHz and 6 GHz which is the work frequency of Wireless local area networks. The notch is explained by presenting the current distribution in the antenna and indicating the fact that etching the parasitic slot in the dense region of current in desired frequency rejects the radiation in that frequency and the radius of the curve slot determines the location of the notch. An appropriate parametric study result with a bandwidth of 1 GHz for the notch is achieved.
