Design and optimization of 2×2 corporate-series fed microstrip antenna array

Abstract

The limitation of microstrip patch antenna is relatively low gain and narrow bandwidth. By using the microstrip patch antenna array an-tenna performance can be improved. In this paper design and stimulation of a 4 element rectangular microstrip patch array is described and the performance of antenna array is optimized by varying patch element dimensions. Antenna array is designed to operated at the frequency of 10 GHz. The corporate-series feed network is implemented for feeding patch elements. The 2×2 antenna array is imple-mented on FR4 substrate with 1.588mm thickness and dielectric constant of 4.4.The stimulation and performance analyze of antenna is done using Ansoft High frequency structure simulator software. Finally, comparison of antenna array characteristics before and after optimization is presented.
