초록

In this paper, a novel compact microstrip-fed antenna with band-rejection characteristic for wideband applications is proposed. By cutting an L-shaped notch on the radiation patch, the wideband property for the proposed antenna is achieved. In addition, a C-shaped slot is introduced to obtain the band rejection operation of the antenna. The antenna, with very small size of $15.5\times21 mm^2$ including the ground plane, operates over 3.08 to 10.97 GHz and has the rejection band of 5.03 to 5.91 GHz for $S_{11}$ < -10 dB.
