ABSTRACT:
Radially fed microwave signal combiner/distributor apparatus comprising a central coaxial connector which is coupled via radially extending paths to several circumferential coaxial connectors which are equiangularly disposed on the circumference of a circle surrounding the central connector, the apparatus including a generally discoidal microwave transmission cavity through which the paths extend, which cavity communicates at the center thereof with the central coaxial connector and which cavity communicates at the circumferential periphery thereof with the circumferential coaxial connectors via a conductive annulus, which annulus is spaced away from the internal circumferential periphery of the cavity, and to which annulus the inner conductors of the circumferential coaxial connectors are electrically connected at locations equiangularly spaced around the annulus.
