BIASING MAGNET HOLDER - TUNING CAP FOR DIELECTRIC WAVEGUIDECIRCULATOR

摘要

A Y-junction dielectric waveguide circulator is provided with a dielectric support plate. At the vertex of adjacent dielectric waveguides are positioned metal tuning legs. These tuning legs are spaced from the waveguides and extend higher than them. Preferably the tuning legs are made integral with a cap positioned above the circulator junction. This cap also serves as a holder for the upper biasing magnet. The lower magnet is centered under the junction and bonded to the bottom of the support plate.
