Abstract
Provided is a horn antenna for circular polarization using a planar radiator. The horn antenna has a simplified and miniaturized structure by substituting a function of a providing signal power to the horn antenna with a function of a circular polarizer which induces circular polarization by using the planar radiator. The horn antenna includes: a horn for radiating signal power; and a planar radiator for providing the signal power to the horn to thereby induce circular polarization, the radiator including a radiating patch.
