  • the conventional antenna apparatus has been provided to allow most heat to be dissipated rearward from the antenna housing part by intensively mounting a heating element with a generally large heating amount on a rear portion of the main board or the PSU board and arranging a filter between the antenna element assembly and the main board or the PSU board.
  • the filter on the installation space is mostly disposed between the main board or PSU board disposed behind the filter and the antenna element assembly disposed in front of the filter for the shortest connection of electrical signals.
  • a technical feature of the antenna apparatus 100 is that the antenna element assembly 300 is exposed to front outside air and designed and manufactured so that no additional installation of the radome is required, while the arrangement of the filter 500 on the installation space of the antenna housing part 110 and 120 is also designed to enable or be advantageous for forward heat dissipation of the heating elements installed on the main board 410 or the PSU board 420.
  • the plurality of forward heat dissipation fins 111 are formed integrally with the front housing 110 so that the plurality of forward heat dissipation fins 111 protrudes forward by a predetermined length from the front surface of the front housing 110 of the antenna housing part 110 and 120 and serves to increase a heat transfer surface area of the front surface of the front housing 110 made of a thermally conductive material (e.g., a metal material).
