Dual Band Notched Small Square Monopole UWB Antenna with Enhanced Bandwidth

This paper presents a small square monopole antenna with dual band-notched function which works for UWB applications. In this antenna there is a square radiating patch with an E-shaped slot, and a C-shaped slot at the middle of the patch and two L-shaped slot and one V-shaped strip in the ground plane which gives a wide fractional bandwidth of more than 140% (3.4-20 GHz) is consisted. The presented antenna has been successfully simulated, and shows the bandwidth for the voltage standing wave ratio 2 with two notched bands. The presented antenna has a small size of 10× 12 mm². This antenna gives good radiation behavior within the UWB frequency band it is shown by simulated results.
