Abstract

In this article, a new frequency notched ultra‐wideband microstrip slot antenna with an S‐shaped slot in the radiating stub and a pair of C‐shaped slots in the ground structure is proposed and experimentally studied. To increase the bandwidth, a pair of C‐shaped slots was cut in the ground plane that improves the bandwidth especially at the higher frequency and provides a wide usable fractional bandwidth from 2.9 to 14.4 (135%). To generate single band‐notch characteristics, we use the S‐shaped slot in the square radiating stub that with this design, a frequency notched band of 5.07–5.93 GHz has been achieved. The proposed antenna displays a good omni‐directional radiation pattern even at higher frequencies. The measured results reveal that the presented single band‐notch slot antenna offers a very wide bandwidth with notched band. The designed antenna has a small size of 20 × 20 mm^2^. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett 54:515–518, 2012; View this article online at wileyonlinelibrary.com.
