ABSTRACT:
A resonant structure and filter include a resonant element mounted to the cover of a housing. A transmission line passes through the cover and is connected to a coupling loop. The coupling loop is located adjacent the resonator and is connected to ground. A coupling tuner is attached to the housing and includes a post which is movably attached to the housing. The tuner extends between the coupling loop and the resonator, and may be adjusted to change the electromagnetic coupling.
