Compact ultra-wideband printed antenna with band-rejection characteristic

Abstract

A novel and compact ultra-wideband printed antenna with band-rejection characteristic is proposed. By cutting an L-shaped notch on the radiating patch, the impedance bandwidth of the proposed antenna can be enhanced. In addition, a C-shaped slot is introduced to obtain the band-rejection operation of the antenna. The antenna, with compact size of 15.5×21 mm including the ground plane, operates over 3.08–10.97 GHz and has the rejected band from 5.03 to 5.91 GHz.
