Abstract
A circuit dividing and/or combining signals that has an input port for receiving a first signal, a first transmission line connected at one end to the input port, and a first connection point. The first connection point is connected to another end of the first transmission line. The first connection point provides a path to a first output port. A plurality of additional transmission lines, connection points and output ports is connected in sequence. Each transmission line is connected at one end to the (N−1)th connection point. A N connection point is connected to another end of the N transmission line. The N connection point provides a path to a N output port. The circuit provides equal amplitude at each of the anntena ports and further provides 90° phase progression between each pair of adjacent output ports.
Claims3
A feed network comprising:
- an input port for receiving or sending a first signal:
- a first transmission line connected at one end to said input port;
- a first connection point, said first connection point connected to another end of said first transmission line, said first connection point providing a path to a first output port;
- plurality of additional transmission lines, connection points and output ports, serially connected such that each Nth transmission line is connected at one end to (N−1)th connection point;
- each Nth connection point is connected to another end of the Nth transmission line, said Nth connection point providing a path to a Nth output part;
- wherein said feed network provides equal amplitude at each of said output ports and further wherein said circuit provides 90° phase progression between each pair of adjacent output ports, wherein said feed network further comprises a package for mounting on the surface of an electronic circuit board, said package including at least two sheets of dielectric material, said sheets bonded together, each of said sheets including a metal ground plane on its unbonded surface.
