This paper describes the design and realization of an extra high frequency band 8 ° 8 microstrip Butler matrix. Operation at 36 GHz is achieved with a frequency bandwidth exceeding 400 MHz. The circuit is implemented on a bi‐layer microstrip structure using conventional manufacturing processes. This planar implementation of a Butler matrix is a key component of a switched beam smart antenna with printed antenna elements integrated on‐board. Conception details, simulation results, and measurements are also given for the components (hybrid couplers, cross‐couplers, and vertical inter‐connections) used to implement the matrix.
