A simultaneous conjugate-matching algorithm for N-element array antennas

Abstract

This paper presents an automatic impedance-matching algorithm that can sequentially realize a simultaneous conjugate-matching state for all the elements in an N-element array antenna. The analytical results show that the converged solution obtained from the proposed algorithm agrees well with the solution calculated by the analytical deterministic equation, confirming the validity of the proposed method. The method can be applied to MIMO array antennas.
