UWB Antenna with Band Rejection for WLAN/WIMAX Band

摘要

Owing to the progress in the field of wireless communication, UWB antenna has procuring more attention. A novel and compact ultrawideband antenna has been proposed for triple band notched rejection. The first rejection band is obtained by etching the C-shaped type slot in the partial ground structure. The second and last rejection bands are obtained by inserting the inverting and noninverting C-shaped type slots in the patch, respectively. The proposed antenna shows better radiation pattern, constant gain over the ultrawideband but not in the rejected frequency band. CST Microwave Studio Software is used for optimizing the parameters of UWB antenna having the capability for rejecting the three-stop band.
