A Thick Film Microstrip Butler Matrix for the Frequency Range 1.5-1.7 GHz.

Abstract

This Report describes the design, construction and electrical measurement of a 4 x 4 Butler Matrix for the 1.5-1.7 GHz frequency range. The Matrix was constructed in thick film technology on an alumina substrate. A computer aided design package was used for the circuit synthesis. A Butler Matrix is a passive multiport component which when loaded with radiating elements enables production of a beam of microwave energy in a specified direction in space, dependent upon which input port is activated. The Butler Matrix consists of an equal number of input and output ports connected through an array of phase shifters and couplers such that when a signal is applied to any input port it produces equal amplitude signals at all output ports.
