UWB CPW-fed monopole antenna with a band-notch function

In this paper a CPW-fed monopole antenna with a size of (24 × 24 × 1.6 mm³) and a staircase feed line is presented. The antenna is designed for operation across the entire UWB from 3.1 to 10.6 GHz with band-notch in 5–6 GHz, by inserting a H-shape slot on the proposed CPW feeder. By changing in width and length of H-shape slot, the operation on notch-band becomes different. The proposed antenna has a reflection coefficient below -10 dB through the band frequency and reasonable gain values over the same frequency band.
