COAXIAL TRANSMISSION-LINE MATRIX INCLUDING IN-PLANE CROSSOVER An assembly (108) of coaxial transmission lines (22) and coupling devices (28, 30) formed of closely spaced center conductors (32) of the coaxial lines, is formed within a planar configuration. The coupling devices are arranged either singly, or in pairs with one coupling device behind the other coupling device, to provide for a division of power between transmission lines and to provide for a crossing over of power from one transmission line to another transmission line. The transmission-line assembly is reciprocal in operation so that the singly arranged coupling devices may be employed for a distribution as well as for a combination of electromagnetic waves. Phase shifters (122) may also be included to provide a desired phase relationship among waves outputted by various ones of the transmission lines. The transmission lines, the coupling devices and the phase shifters may all be fabricated in a parallel array within a common metallic plate (24) by automated milling machines for facile, accurate, and reproducible manufacture of the transmission-line assembly. The assembly including the matrix of coaxial lines for electromagnetic waves is readily structured to serve as a Butler matrix. |
