Abstract
A suspended substrate rat-race coupler utilizes an elliptic configuration of the usual circular rat-race coupler on a circuit card positioned within below cut-off suspended substrate housing channels. The channels within the suspended substrate housing are positioned to receive the arms of the elliptical rat-race coupler. The longitudinal axis of two of the suspended substrate channels are offset with respect to each other to accommodate the rat-race arms and are positioned either on the same side of a primary suspended substrate channel or on opposite sides of the primary suspended substrate channel. Connections to the four ports of the rat-race can thus be made without disrupting the TEM propagation mode within the suspended substrate device.
