Antenna apparatus

An antenna apparatus comprising:

• a main body module in which a main board is embedded;
• a radio frequency (RF) module fixed to a front of the main body module so that an intermediate outside air layer is formed between the main body module and the RF module and having an RF filter unit and an antenna element unit embedded therein;
• and
• an amplification unit module disposed to be exposed to the intermediate outside air layer between the main body module and the RF module and including an amplification unit substrate on which analog amplification elements are mounted,
• wherein heat generated from heating elements mounted on the main board is dissipated through at least any one of the front and a rear of the main body module,
• heat generated from the amplification unit module is directly dissipated through the intermediate outside air layer;
• and
• a finger guard panel configured to partition the intermediate outside air layer between the main body module and the RF module from an outer space and formed with a plurality of airflow holes through which outside air of the outer space flows into the intermediate outside air layer or inside air of the intermediate outside air layer flows out to the outer space.
