Abstract

PURPOSE:To save the space and to make the filter compact, by picking up electromagnetic waves of two frequency bands with one filter and branching remaining electromagnetic waves so that they can be transmitted. CONSTITUTION:A cubic filter 6a is constituted from two types of flat plate filters 7a, 7b. Taking the filters 7a, 7b are reflect only the electromagnetic waves in frequency bands f1, f1', the wave of f1 toward dotted lines, that of f1' toward broken lines, and remaining waves toward solid lines are advanced. After the waves of f1, f1' are reflected respectively at the filters 7a, 7b, to obtain the same phase for both the waves, it is necessary that the least common multiple of the waves in f1, f1' is equal to the length of a diagonal of a square. With this constitution, the branching filter can be constituted with smaller space in branching electromagnetic waves of many frequency bands, by using a cubic filter 6.
