A thick film microstrip Butler matrix for the frequency range 1.5 to 1.7 GHz
Abstract
The design, construction, and electrical measurement of a 4 by 4 Butler Matrix for the 1.5 to 1.7 GHz frequency range are described. The Matrix was constructed in thick film technology on an alumina substrate. A computer aided design package was used for the circuit synthesis. As an application example, the use of this Matrix as a submatrix for a 16 by 16 Matrix which could be part of the feed system of a satellite borne steerable beam phased array of radiators allowing complete Earth coverage is discussed.
