An improved uncalibrated metal diaphragm antenna diplexer

摘要

An improved uncalibrated metal diaphragm antenna diplexer comprises an outer conductive metal material casing (2), containing a metal thin sheet extending longitudinally of said diplexer and thereon diaphragms (6) defining therebetween resonating cavities (7) are formed, said casing (2) further supporting signal input/output guides (8, 9) and a T joint (5), characterized in that the first/last of said resonating cavities (7A) is formed at said inlet/output guides (8, 9).
