Abstract
The conventional hybrid tee, which is symmetrical and reciprocal, has been used exclusively in mixer and impedance bridges in microwave engineering. The interconnection of the E-arm and H-arm of the hybrid tee through a 90-degree twist and a phase-shifter by Ishii and Jenners has turned the magic tee into a reentrant hybrid tee with different properties. Ishii and Jenners' paper on the different attenuation levels of port 1 and port 2 of the reentrant hybrid tee has aroused the public interest about the characteristics of the reentrant hybrid tee. It is intended in this study to investigate the characteristics of the reentrant hybrid tee experimentally and theoretically. In the experiment, the author has done the measurements about attenuation, VSWR and impedance against the variation of frequency or phase-shifter setting of the reentrant loop. In theory, the author has derived a general equation for the reentrant hybrid tee, in terms of the scattering parameters of a basic hybrid tee. Conclusions were made about the reentrant hybrid tee by combining the experimental results and theoretical equations.
