Abstract

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 x 20 x 1 mm3 while showing the band rejection performance in the frequency range of 4.27.2 GHz.(c) 2012 Wiley Periodicals, Inc.
