Claims
- 1. 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.
- 2. The feed network of claim 1 wherein said input port, said transmission lines, said connection points, said paths and said output ports are placed between said sheets.
- 3. The feed network of claim 2 wherein said paths comprise copper stripline.
