Compact printed ultra-wideband antenna with dual band- notch characteristics

A compact printed planar ultra-wideband antenna with dual band-notched is proposed. The proposed antenna consists of a rectangular radiating patch and a modified partial ground plane. Two rectangular parasitic strips are placed below the substrate to achieve dual band-notched characteristics. The measured results show that the proposed antenna achieved a wide impedance bandwidth from 2.87 to more than 11 GHz, defined by −10 dB return loss with one notch frequency band at 3.3 to 3.8 GHz and the other at 5.1 to 5.6 GHz. Compared to the other designs, the proposed antenna has a simple structure to achieve the notch-band characteristics to reduce the potential interference between UWB and existing WiMAX and WLAN systems. A stable radiation pattern and flat gain except in the notched bands makes the proposed antenna suitable for being used in UWB applications.
