Closed-Form Design Formulations of Arbitrary Phase Delay Crossover Based on Admittance Matrix

Progress In Electromagnetics Research Letters, Vol. 43, 165-173, 2013
Abstract
A design method for four-port crossover with arbitrary phase delay is proposed in this paper. This method is based on admittance matrix. Closed-form design formulations are deduced by making the structure admittance matrix equal to theoretical one. A crossover with 45˚ phase delay is designed and fabricated for theory verification. In the Butler beam forming network, this crossover has two functions for making the elimination of the 45˚ phase shifter possible and being used for circuit layout. Thus compact structure and good performance of Butler network can be realized.
