Abstract

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.
