JCS_V6_N2_RP4 Square Shape Ultrawideband Antenna for Triple Band Notch Characteristics by Using Notch at Ground Plane Upasana Verma Sudhanshu Verma Journal on Communication Engineering and Systems 2277-5242 6 2 15 19 Ultra WideBand (UWB) Antenna, WLAN Band, WiMAX Band, X-band Satellite Communication, Triple Notch Bands This paper represents the compact Ultra Wide Band antenna with notch characteristics. The proposed antenna consists of stubs, slots, and strips to create the notch characteristics. To reduce the size of antenna and to get the better rejection characteristics, it uses notches at the ground structure and slot techniques. This antenna is used to eliminate the potential interference caused by narrow band services along with reduction in size of antenna. This antenna uses T-shaped stub, inverted U-shaped strips near the feedline, and T-shaped slot at the edge of patch. VSWR of antenna without notch band is nearly equal to 2. This antenna gives the rejection for WiMAX band (3.3-3.7 GHz), WLAN band (5.725-5.825 GHz), and Xband satellite communication (7.250-7.745 GHz).
