Title:
ANTENNA FEEDER CIRCUIT
Document Type and Number:
Japanese Patent JP2018093387
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an antenna feeder circuit, exciting circular polarization, capable of achieving low cross polarization while maintaining a compact size.SOLUTION: A 90-degree two-distribution circuit 6 is connected with a low-range right-handed circular polarization terminal 7 and a low-range left-handed circular polarization terminal 8 to distribute a radio wave at a 90-degree phase difference. A phase adjustment circuit 5 is connected with the 90-degree two-distribution circuit 6 and is constituted of a bypass waveguide. An antiphase two-distribution circuit 4 is connected with the phase adjustment circuit 5 to further distribute each of two radio waves distributed by the 90-degree two-distribution circuit 6. An OMJ 2 is connected with the antiphase two-distribution circuit 4 and connected with a radiation antenna terminal 1 to synthesize the radio wave distributed by the antiphase two-distribution circuit 4.SELECTED DRAWING: Figure 2
