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.
