A miniaturized monopole antenna design with filtering properties is presented.The proposed antenna has a leaf‐shaped radiating patch, which enhances antenna with larger current path leading to wider impedance matching bandwidth in lower frequencies. By creating two ellipse‐shaped slots with the same radiuses on the radiating patch and locating a parasitic circle on the opposite side, a band‐stop property is obtained. Its band‐stop characteristic is controlled by changing the slots' length and circle's radius. The designed antenna has a small size of 20 × 20 × 1 mm 3 while showing the band rejection performance in the frequency range of 4.2–7.2 GHz. © 2012 Wiley Periodicals, Inc.
