A fast and effective method for the matching of two- element symmetric antenna arrays is presented. The full geometry is subdivided into two half-space problems with the help of an even- and odd-mode (EOM) analysis scheme. An interpretation based on the EOM representation is made for any radiation pattern mode that is constructed by arbitrarily exciting the antenna ports. Also, a relationship between the radiation efficiency for the full geometry and the even- and odd-mode S-parameters is derived. A unique technique for matching the two-element antenna arrays is developed by exploiting the EOM representation. Numerical examples that illustrate the effectiveness of our matching technique for different radiation pattern modes are provided. © 2002 John Wiley & Sons, Inc.
