The present study demonstrates the designing and characterization of a circular patch antenna having an impedance bandwidth of 2.4–13.8 GHz with band notch at WLAN operating region. The small size (30 × 40 mm 2 ) and large bandwidth (140.7% fractional band width) makes it suitable for different UWB applications. Different size reduction and matching techniques are used in this model to achieve a better response. The Quarter wave transformer matching technique is used for broad band impedance matching between the radiating circular patch and the 50 ohm source impedance. The simple design and good agreement between the simulation and the experimental results makes the design a suitable candidate for practical applications. © 2016 Wiley Periodicals, Inc.
