Wideband Notched Rectangular DRA

Dong Wen Liu, Daniel Msilanga

Abstract: In this work, a wideband notched rectangular DRA is presented. The proposed antenna is placed on a rectangular ground plane and four notches of equal size and equally spaced are grooved at the bottom before excited by a probe to give a wide 10-dB impedance bandwidth of 37.8 % between 2.25GHz and 3.3GHz. The antenna has an average gain of 4.45dBi with broadside radiation pattern as expected. HFSS2014 is main tool used in this study.
