A UWB band-rejected antenna with embedded nonuniform microstrip line

Abstract

An ultra-wide band (UWB) antenna with band rejection on the range of the wireless local area network (WLAN) is proposed. The antenna consists of a radiation element with broadband radiation and a nonuniform microstrip line for necessary band rejection. The nonuniform microstrip line is designed by the inverse scattering technique. A fabricated antenna is well designed and radiates properly in the UWB range except the WLAN range.
