Abstract

In this paper, a novel antenna design constituting a semicircular slot excited by an extended semicircular patch is presented. The operational bandwidth of this antenna extends from 2.3 GHz to 12.7 GHz, to cover the UWB range of frequencies and Bluetooth, covering almost all indoor communication system applications. Two frequency notches were implemented to ensure coexistence with the narrow band applications sharing some of these frequency bands namely, WLAN and WiMAX (3.3-3.6 GHz and 5-6 GHz). These notches were obtained by using L-slit in the ground plane and C-slot in the tuning patch, the dimensions of which were optimized using parametric analysis. The proposed antenna was fabricated using photolithographic technique. Measured and simulated results were compared and very good agreement was observed. The bandwidth of the proposed antenna increased by almost 2.5 GHz (30%) than previously presented UWB antennas with dual frequency notches, especially at the lower end of the spectrum which enables inclusion of Bluetooth applications.
