1. An antenna apparatus comprising:
- an antenna main body for transmitting or receiving a linearly polarized wave a case which houses said antenna body in accordance with a direction of polarization of a radio wave to be used; and
a heat sink which is disposed at a surface of said case which serves as a radio emission/receiving surface of said antenna main body when said case is fixed, said heat sink including a row of radiating fins protruded in a direction where the radio wave is incident onto the surface of said case or emitted from the surface of said case, wherein the radiating fins of said heat sink e shaped such that upper ends of grooves between the radiation fins in a vertical direction are open, when the ease is fixed.

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.
