Abstract (en)
A horn array antenna (1) for dual linear polarization receiving a first polarization wave and a second polarization wave comprises a plurality of horns (10) to which a mixed wave of the first polarization wave and the second polarization wave enters; a plurality of polarization filtering units (20) provided in each of the horns to separate the incident mixed wave into the first and second polarization waves; a first polarization guide (30) which guides the first polarization waves separated at the polarization filtering units; and a second polarization guide (50) which guides the second polarization waves separated at the polarization filtering units. An upper portion of each polarization filtering unit is formed as a quadrilateral space and each polarization filtering unit has four walls including a first, second, third and fourth walls. A stepped portion (25) is extended from a lower portion of the first wall to an interior of the polarization filtering unit, whereby a lower portion of the polarization filtering unit is formed as a quadrilateral space with a narrower width than that of the upper portion. An extended portion is formed on an upper portion of the stepped portion and a first polarization inlet is formed on the second wall opposite to the first wall to provide the first polarization wave to the first polarization guide.
