چکیده
In this paper, we have investigated a printed modified circular disc monopole antenna with cross-shaped slot in radiating patch for UWB applications. The proposed antenna covers the entire UWB band (i.e., 3.1GHz to 10.6GHz) except the frequency band of IEEE 802.11a (i.e., from 5.15GHz to 5.83GHz). This UWB antenna will be of use in environments where IEEE 802.11a WLAN devices are already in operation, such UWB antenna could coexist with IEEE 802.11a devices without any interference. Simple rectangular microstrip line is used for feeding the printed monopole antenna. We have simulated modified circular disk monopole antenna with cross-shaped slot using Zeland IE3D software and it has been observed that the notch frequency response of the antenna can be adjusted by the changing the position of the cross-shaped slot in the radiating patch.

A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...
