HORN ANTENNA

摘要

The present invention relates to a horn antenna. The horn antenna capable of increasing gain at a low frequency includes: a first radiation part which forms a first loop, and has a shape spread toward a radiation direction; a second radiation part which forms a second loop, and is arranged at one side of the first radiation part, and has a shape spread toward a radiation direction; and a support plate which supports the first and the second radiation part in order for the first and the second loop to be coupled. The first radiation part includes an elliptical part formed to increase gain at a low frequency, and the first and the second radiation part are formed in an asymmetric shape to widen a frequency operation band at the low frequency.
