SINGLE LINEAR POLARIZATION HORN ARRAY TYPE ANTENNA USING SKEW FILTER

摘要

A single linear polarization horn array antenna is provided to enhance the receiving efficiency by applying a skew filter to the single linear polarization horn array antenna. A horn array antenna is comprised of a plurality of horns(100), a guide and a skew filter. The electromagnetic wave enters to the horns. The guide guides the electromagnetic wave entered to the horn. The skew filter changes the angle of the electromagnetic wave. The skew filter has a shape of comb teeth. The angle of the comb teeth is determined based on the region location of the single linear polarization horn array antenna used or the entering angle of the electromagnetic wave.
