A novel UWB antenna with band-elimination characteristic is presented. The proposed antenna is fed by microstrip line and consists of an inversed bell-shape radiation patch, rounded ground, and a ring-shaped parasitic patch. The proposed antenna utilizes a ring-shape parasitic patch to reject the frequency band (5.15-5.825 GHz) limited by IEEE 802.11a and HIPERLAN/2. In addition, the rejected frequency band call be varied by adjusting the length and location of the ring-shape parasitic patch. By means of a normalized antenna transfer function, both the frequency-domain and time-domain characteristics of the antenna are carefully investigated. The fabricated antenna call achieve broad bandwidth covering 2.2 to 11.8 GHz with VSWR below 2. (c) 2006 Wiley Periodicals, Inc.
