Analysis of electrically adjustable antenna arrays

In this paper, the multi-port connection method is used to evaluate the system of electrically adjustable antenna arrays. The whole system is divided into several subsections, the scattering matrix for the whole network is obtained while the scattering matrix of each subnet are given. Then the currents on each antenna element are calculated based on the scattering matrix. Finally the radiation patterns of the array are calculated according to the principle of pattern multiplication.
