Abstract
This paper presents a microstrip array antenna which contains the effect of fractal iterated patches with the influence of a two layer staked structure in 2×2 array structure, for attaining both high gain and wide bandwidth properties. The simulated results exhibit that the proposed antenna has 96.50% radiation efficiency and maximum total efficiency of 92.78% with a high gain of 12.5 dB. The antenna exhibits a high bandwidth of 1.50GHz (10.15%) from 14.04GHz to 15.54GHz around the center frequency of 15GHz.The proposed antenna owns encouraging performances of higher gain, wider bandwidth and higher efficiency which makes it a most likely candidate to work in Ku-band suitable for satellite based applications.
