HORN ARRAY TYPE ANTENNA FOR DUAL LINEAR POLARIZATION AND HORN USING THE SAME

摘要

A dual linear polarization horn array antenna and the horn are provided to improve the performance of the antenna by forming at least one protrusion in an inclined part. A dual linear polarization horn array antenna(1) includes at least one horn(10), a first polarization guide(30), a second polarization guide(50). The horn is tapered along a progressive direction of an electromagnetic wave. The horn guides the electromagnetic wave. The horn includes a polarization filtering unit. The polarization filtering unit separates the first polarization and the second polarization. The field direction of the first polarization is at right angles to the field direction of the second polarization. The first polarization guide guides the first polarization separated by the polarization filtering unit. The second polarization of the polarization filtering unit guides the second polarization separated by the polarization filtering unit.
