ANTENNA POWER SUPPLY CIRCUIT

摘要

An antenna feed circuit includes: a first hybrid circuit (2) having a reference phase second terminal and 90° lagging phase third terminal; a second hybrid circuit (3) having a first terminal connecting to the first hybrid circuit (2) second terminal, reference phase second terminal, and 90° lagging phase third terminal; a first polarization converter (4) and a second polarization converter (5) pair outputting at the second hybrid circuit (3) second terminal phase; a third polarization converter (8) and a fourth polarization converter (9) pair outputting at the second hybrid circuit (3) third terminal phase; a third hybrid circuit (12) having a first terminal connecting to first hybrid circuit (2) third terminal, reference phase second terminal, and 90° lagging phase third terminal; a fifth polarization converter (13) and a sixth polarization converter (14) pair outputting at the third hybrid circuit (12) third terminal phase; and a seventh polarization converter (17) and an eighth polarization converter (18) pair outputting at the third hybrid circuit (12) second terminal phase rotated by 180°.
