Abstract

PURPOSE:To simplify constitution, and also to improve VSWR characteristics by making the pressure plug of a corrugate groove at a coaxial line part into a waffle iron filter and by providing the corrugate groove to the inner wall of an exclusive- use waveguide. CONSTITUTION:Pressure plug 2 of corrugate groove 3 to be provided to the coaxial line part is deformed into shape 50 to form coaxial line type waffle iron filter 7, and the inner wall of exclusive-use circular waveguide 4 is provided newly with corrugate groove 3 whose admittance Yc shows inductive susceptance to high-frequency wave (fH). In the branching filter of this constitution, filter 7 operates when (fH) leaks to the coaxial line, and then inhibits all mode waves of (fH) from passing through, so that the need for providing filter 7 to rectangular waveguide 6 of coaxial line type polarizer 8 will be eliminated. As a result, branching filter 8 branching low-frequency wave (fL) is simplified and matching becomes easy, thereby obtaining excellent VSWR characteristics.
