Abstract
Abstract A electromagnetic energy coupling network for reciprocally processing or combining electromagnetic energy flowing in pluralities of transmission lines is disclosed. The coupling element is a multiple port transmission line junction associated with tapered transmission lines and efficiency transferring energy inputs on such lines into a wave flowing only from a single output port. The network may be employed individually or in multiple quantities as an element in complex coupling tree network matrices for the processing of individual impulse signals received by the elements of an antenna array. In application in such signal combining tree matrices, means are provided in the matrix depending upon inherent properties of the coupling element for degrading the adverse effects of internally generated spurious signals.
