Title:
WAVEGUIDE MULTI-STAGE BRANCHING CIRCUIT
Document Type and Number:
Japanese Patent JPH05218713
Kind Code:
A
Abstract:
PURPOSE: To uniformize distribution power to a branching side waveguide by deviating the branching section center line of a 2nd H plane T branch to an oppositeside to the input waveguide of a 1st H plane T branch in a waveguide multi-stage branching circuit having H plane T branches very close to each other.
CONSTITUTION: The branching load 10 of the 2nd H plane T branch 2 is deviated by a distance d1 from a branching section center line 9 toward a branching side waveguide 5. The distance d1 is set so that the power distributed to branching side waveguides 4, 5 of the branch 2 is nearly equal to each other. Further a part of a coupling section waveguide 7 may be cut off or a thin projection may be provided thereon.
