Abstract
A multiple conductor radio-frequency transmission line including a plurality of conductive traces, an input port, and at least one output port is disclosed. The input port includes a radio-frequency signal input line which is generally aligned with and disposed in a partially or completely overlapping relationship with the plurality of conductive traces at the input port, with the radio-frequency signal input line being at least as wide as the plurality of conductive traces at the input port. The output port includes a radio-frequency signal output line which is generally aligned with and disposed in a partially or completely overlapping relationship with at least one of the plurality of conductive traces at the at least one output port, with the radio-frequency signal output line being at least as wide as the at least one of the plurality of conductive traces at the output port. The input and output ports provide a capacitively coupled, multi-conductor structure capable of simultaneously distributing primary radio-frequency signals and secondary control signals from the input port to one or more output ports in systems such a phased array radars and wireless communications systems…
