Abstract
Ultra wide bands antennas with notched bands characteristics have recently been considered for efficient communication between devices. In this paper, a compact ultra-wideband antenna (UWB) for UWB applications with triple bandnotched characteristics is presented. The proposed antenna consists of a square patch with four truncated corners and a partial ground plane with a rectangular slit. The operation bandwidth of the designed antenna is from 2.66 GHz to more than 13.5 GHz. Band-notched characteristics of antenna to reject the frequency band of 3.18 - 3.59 GHz and 4.70 - 5.88 GHz, is realized by inserting two C-shaped slots in the patch, the third band of 9.54 - 12.22 GHz is achieved by slottype capacitively-loaded loop (CLL) inserted in the patch near the feed line. Details of the proposed antenna design and simulated results are presented and discussed.

Summary
Ultra-wideband (UWB) communication systems have become one of the most fascinating wireless topic since the commercial uses of frequency band from 3.1 GHz to 10.6 GHz were approved by Federal Communications Commission (FCC) in 2002 [1]. To satisfy the increasing demand for wireless communication, various ultra-wideband antennas have been studied [2]. To satisfy such requirement various ultrawideband antennas with notched band have been studied [5,6,7,8,9,10,11,12,13,14,15,16,17] To introduce such a band-notched function, several methods have been proposed, including embedding a slot of different shapes in the radiating patch, or in the ground plane, using parasitic patches, embedding a slit in the feeding strip, or etching split ring resonator (SRR) coupled to the feed-line [9], or the CSRR (the negative image of SRR) structure [18]. The details of the proposed antenna are presented and the simulation of the VSWR and radiation patterns of antenna are presented and examined
