A very compact microstrip fed triple band notched (Ultra Wide Band)UWB antenna is presented here. The antenna uses open ended quarter wavelength slot in the patch for rejecting 3.5 GHz (WiMAX) and a half wavelength slot in patch and ground respectively for rejecting 5.5 GHz (WLAN) and 8.2 GHz( ITU 'X' downlink band)respectively. While embedding the whole three rejection bands design to the compact UWB antenna, the main problem faced was the cross coupling between the bands. The simulated VSWR results and radiation pattern shows that due to the optimum spacing provided between the rejection band design the resultant triple band notched antenna operates fairly at required UWB frequencies without interferences from co-existing bands. The size of this antenna is 14*22*1.6 mm 3 which is very compact. The fractional bandwidth of the proposed antenna is 125%.Good Voltage Standing Ratio (VSWR) and radiation pattern are also obtained in the required UWB band. The compact size of antenna makes it a suitable candidate for Wireless Personal Area Network Applications (WPAN). Keywords-monopole antenna; notched frequency bands,;quarter and half wavelength slots ultra wide band (UWB),Voltage Standing Wave Ratio(VSWR).

“…To keep the antenna footprint unaltered, effective ways to achieve band rejection behavior are inserting strips or slots of various shapes and sizes in the radiating patch/ground plane [2,12] or embedding a tuning stub within a large slot on the patch [4]. Methods using open loop or split ring resonator [3,5,6], inserting the band-rejecting elements integrated in the feed line [7,13], capacitance loaded loop resonator [8], triple-mode resonator [9], electromagnetic band gap structures [10], and triple mode stub loaded resonator [11] have also been presented.…”

Abstract-A new compact and simple design of UWB antenna with triple band-notched characteristic is proposed in this paper. The first band notch for 3.3-3.8 GHz (WiMAX) is created by cutting a line slot in the radiating patch. The second band rejection for 5.1-5.8 GHz (WLAN) is achieved by etching out an elliptical split ring resonator (ESRR) from the patch placed just above the feed line and patch junction. And the third notch for 7.25 GHz-7.75 GHz (X-band satellite downlink frequency) is created using rectangular split ring resonator (RSRR) in the feed line. Each notch can be adjusted without disturbing the others. A 10 dB return loss wide bandwidth (3.1-10.6 GHz) and VSWR > 2 for the stopbands has been measured.
