Abstract

In this paper, an 8-Element MPA array is designed for X-band frequency at 9.1GHz with corporate power divider and then Wilkinson power divider is placed at the first stage to improve the array over all characteristics. The first side lobe level of the array has been decreased from -13.26dB to -16.48dB and the front to back ratio is also increased from 19.59dB to 24.63dB due to combined effect of corporate and Wilkinson power dividers. The overall gain of the antenna has not deteriorated although the radiation efficiency is slightly decreased. In this work, FR4 substrate is considered with thickness h=1.60mm and =4.40.The simulations are carried out using HFSS and the important parameters namely return loss, VSWR and Gain are measured by using vector network analyzer.
