The paper proposes a novel compact Ultra Wide Band (UWB) circular mono pole antenna with single band notch characteristics. The antenna is fed with a 50 W micro strip feed line. In the proposed antenna, a U slot and via hole are made to achieve band notch characteristics. The proposed antenna filters the existing Wireless Local Area Network (WLAN) and the antenna has 30 23 1.6 mm3 size. The antenna gives larger bandwidth from 3.1-15 GHz and it gives good gain for the entire frequency band except at notched band. The antenna is designed using RT/DUROID substrate with permittivity 2.2; it is simulated using CST microwave studio suite 2016, and antenna performance parameters like return loss, VSWR, radiation efficiency and gain are calculated and reported.

 
 

Ultra Wide Band (UWB) technology is one of the emerging technologies for short range communication to get high data rates. With the advancements in wireless technologies, compact and low profile simple antennas are required, which are suitable for wireless applications. In 2002, Federal Communication Commission (FCC) approved unlicensed frequency band from 3.1 to 10.6 GHz with effective isotropic radiated power spectral density of 41.3 dBM/MHz (Hsuand, 2006; Zhang et al., 2008; George and Sreenivasam, 2010; and Jamal et al., 2014).

Avoiding the interference with existing narrow band services is the main challenge to design a compact wide band antenna with band notching characteristics (Gao et al., 2005; Hong et al., 2007; Wu et al., 2007; Moghadasi et al., 2008; Qi et al., 2008; Nguyen et al., 2012;
