Antenna apparatus

Abstract

The present disclosure relates to an antenna apparatus, and especially comprises: a main body module in which a main board is mounted; an RF module which is fixed to the front so that an intermediate outside air layer is formed between the RF module and the main body module, and in which an RF filter unit and an antenna element unit are mounted; and an amplification unit module which is disposed so as to be exposed in the intermediate outside air layer between the main body module and the RF module, and comprises an amplification unit substrate having analog amplification elements mounted thereon, wherein heat generated from heating elements mounted on the main board is dissipated through at least any one of the front and back of the main body module, and heat generated from the amplification unit module is directly dissipated through the intermediate outside air layer, and thus the advantage of enabling maximum heat dissipation performance is provided.
