Abstract
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 can 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 can achieve broad bandwidth covering 2.2 to 11.8 GHz with VSWR below 2. © 2006 Wiley Periodicals, Inc.
