Wideband Flipped Staired Equilateral Triangular Pyramid DRA

In this paper, a flipped staired equilateral triangular pyramid DRA is presented. The proposed antenna is placed on rectangular slot of a ground plane and excited by a microstrip line to give a wide 10-dB impedance bandwidth of 36 % between X-band and Ku-band. The antenna has an average gain of 7dbi with a variation of 2dBi across impedance passband. Also, the antenna exhibit broadside radiation pattern as expected. This study was done using CST Microwave studio software.
