HORN ARRAY TYPE ANTENNA FOR DUAL LINEAR POLARIZATION

摘要

A dual linear polarization horn array antenna is provided to reduce the height of the horn by forming a first protrusion and a second protrusion in the horn. The first polarization and the second polarization are inputted to a plurality of horns(10). Each horn has a polarization filtering unit(20). A polarization filtering unit separates the first polarization and the second polarization. A first polarization guide guides the first polarization separated by a plurality of polarization filtering units. A second polarization guide guides the second polarization separated by the plurality of polarization filtering units. The first polarization guide includes first and second guide tubes(31,32), a first intermediate tube(40) and a first mixing tube(45). The first guide tube receives the first polarization separated by the first and second polarization filtering units. The second guide tube receives the first polarization separated by the third and fourth polarization filtering units. The first intermediate tube mixes the first polarization provided from the first and second guide tubes. The first mixing tube receives the first polarization mixed in the first intermediate tube.
