ANTENNA SYSTEM FOR SIMULTANEOUS TRIPLE-BAND SATELLITE COMMUNICATION

摘要

According to an embodiment of the present invention, a triple-band antenna system for satellite communication includes: a feed horn device which radiates or absorbs triple-band wireless signals including X, Ku, and Ka bands at the same time; and a wave guide unit which is combined to the feed horn and transmits input/output of the wireless signals. The feed horn device includes: a corrugation horn which radiates or absorbs wireless signals in the X and Ku band, has a bell shape, and has a plurality of stepped corrugations on the inner circumferential surface; and a dielectric feed which radiates or absorbs wireless signals in the Ka band and is placed at the central area of the corrugation horn.
