A novel compact coplanar waveguide‐fed antenna is presented with triple band‐notched characteristics. A C‐slot is etched in a novel patch to avoid interference from WiMAX band. By using pair of CSRR slots and pair of L‐shaped slits in ground plane, two notched bands for WLAN and ITU 8 GHz bands are obtained, respectively. The antenna has bandwidth of 2.8–11.2 GHz with three notched bands of 3.3–3.7 GHz, 5–6 GHz, and 8–8.4 GHz to avoid interference from WiMAX, WLAN, and ITU 8 GHz bands, respectively. The antenna has good impedance matching and stable radiation patterns. Good agreement is reached between measured and simulated results. © 2013 Wiley Periodicals, Inc.
