ABSTRACT:
A multiple-port loop-coupled commutating feed for a circular or cylindrical antenna array which is circumferentially scanned. A rotor assembly having a plurality of elongated coupling loops circumferentially spaced about an arc of its perimeter is fed from a stripline feed configuration excited at the driven central axis of the rotor. The rotor loops are formed by extension of printed circuit traces extant within the stripline feed about an arc of the rotor assembly. A plurality of elongated stator loops with essentially the same radial dimensions as the aforementioned rotor loops is provided, however the stator loops are distributed throughout the full 360.degree. of the circular perimeter of the device to continuously couple a changing fraction of the stator loops to the rotor as the latter is rotated. An output port is provided connected to each stator loop and these output ports may then be discretely connected to corresponding elements of a circular array or columns of elements of a cylindrical array.
