Title:
円偏波アンテナ用給電回路
Document Type and Number:
Japanese Patent JP7101201
Kind Code:
B2
Abstract:
A power feed circuit for a circularly polarized antenna includes a synthesizing-distributing unit and a phase shift unit. The synthesizing-distributing unit distributes input signals to two paths with the same phase and same amplitude. The phase shift unit has two phase shift circuits connected respectively between the two paths distributed by the synthesizing-distributing unit and two feed points of a circularly polarized antenna. The phase shift unit outputs signals whose phase difference is 90° to the two feed points and of the circularly polarized antenna.
