Abstract:
1. A reverse-phase cross coupling structure comprising: a base, said base having a resonance chamber, a plurality of resonators vertically arranged in parallel in said resonance chamber, and a plurality of coupling portions respectively coupled between each two adjacent resonators in said resonance chamber, said coupling portions each having a top recess and a coupling hole vertically downwardly disposed in said top recess; and an adjustment device, said adjustment device comprising a cover plate fixedly covered on a top side of said base, said cover plate having a plurality of through holes corresponding to said coupling holes of said coupling portions, and a plurality of adjustment rods respectively inserted through said through holes of said cover plate and threaded into said coupling holes of said coupling portions of said base and vertically adjustable relative to said coupling portions to a desired elevation to regulate the amount of the reverse-phase cross coupling of said resonators.
