Abstract
The present invention relates to an antenna device and, particularly, comprises: a radiation cover; a plurality of radiation elements which are arranged on the front surface of the radiation cover so as to be exposed to outside air and which implement beamforming; and an antenna housing body on which the radiation cover is provided, wherein the heat, which is generated by a heating element arranged behind the radiation elements and the radiation cover, is released to the front of the antenna housing body through the front surface of the radiation cover and the radiation elements which are exposed to outside air, and thus the radiation performance of a product is remarkably improved, and the manufacturing cost of the product is reduced.
