This paper focuses on the development of a new method for the conception of a Butler matrix to produce a broadside beam using 90° hybrids only. The method used to design an N × N Butler matrix with a broadside beam is described. Moreover, we conceive, simulate, and realize a three‐beam antenna in order to validate this new method. The design and measured results of the antenna fabricated on RT/Duroid6002 substrate over the Ku‐band are presented. © 2005 Wiley Periodicals, Inc.
