Abstract

A new design formulas for a NtimesN matching network for an array antenna with mutual coupling is presented. Using matching conditions, decoupling between excitation ports and beam orthogonality have been explicitly verified. Numerical results of the antenna pattern in the vertical plane suggest that the received power of a two elements array is two times larger than a single dipole. A method for enhancing frequency characteristics and a new definition of a receiving antenna efficiency are also proposed.
