abstract = "A \mathbf{4} * \mathbf{4} substrate integrated waveguide (SIW) butler matrix is designed at 30 GHz. The design of 90° hybrid coupler and crossover which are the components of the butler matrix are discussed using theory of short slot couplers. The butler matrix is simulated and experimentally verified.",
