1. An antenna apparatus comprising:
- an antenna main body for linearly polarized wave which is accommodated in a case in a direction of vertically polarized wave or in a direction of horizontally polarized wave, both of directions being perpendicular to each other; and
a heat sink which is disposed at a rear surface of said case and thermally coupled to said antenna main body to thermally control said antenna main body.

Abstract
An antenna for linearly polarized wave is accommodated in a case in which a heat sink is provided. By rotating the case depending on the vertically polarized wave or the horizontally polarized wave, wireless communication or broadcasting using the vertically polarized wave or the horizontally polarized wave can be selectively realized with high precision.
