Title:
ANTENNA FEEDER CIRCUIT
Document Type and Number:
Japanese Patent JP2020171064
Kind Code:
A
Abstract:
To obtain an antenna feeder circuit that is smaller than a conventional device while having sufficient isolation performance for a high-frequency signal.SOLUTION: An antenna feeder circuit includes a high-frequency band waveguide through which a high-frequency signal is allowed to pass, and a waveguide composed of a 4-branch circuit that demultiplexes and synthesizes a low-frequency signal, and each branched waveguide connected to the 4-branch circuit has a structure in which the waveguide extending in the direction perpendicular to the tube axis direction of the high-frequency band waveguide is bent parallel to the tube axis direction of the high-frequency band waveguide, a low-pass filter that has a low-pass function is loaded near a connection portion with the 4-branch circuit, and a parallel filter that is parallel to the high-pass waveguide axis is loaded at a location at which the waveguide is bent, and the low-pass filter and the parallel filter are separately arranged in each of the branched waveguides.SELECTED DRAWING: Figure 2
