Abstract
A filter feeding network, including a dielectric substrate, where a surface of the dielectric substrate's one side is provided a microstrip line, and a surface of the dielectric substrate's other side is provided with a metal ground; the microstrip line includes first and second power division circuits, and first and second filter circuits; an input and output end of the first filter circuit are respectively connected to the first power division circuit's input and output end correspondingly, the second filter circuit's input and output end are respectively connected to the second power division circuit's input and output end correspondingly, and the input end of the first filter circuit and second filter circuit are in conduction with the metal ground; and first and second power division circuit's output end feeds at least two array antenna units for −45° polarization and +45° polarization respectively.
