- The present disclosure relates to an antenna apparatus, and more specifically, to an antenna apparatus, which facilitates the installation of an indoor or outdoor wall surface and a support pole by arranging a heat dissipation structure so that heat is intensively dissipated to a front portion of an antenna housing part and removing a rear heat dissipation fin.
- In general, an antenna apparatus includes a main board on which predetermined heating elements are mounted, a plurality of filters stacked at a front of the main board, and an antenna element board (or an antenna element assembly) stacked at fronts of the plurality of filters forward from an inner side of an antenna housing part sequentially in an installation space of the antenna housing part with an open front portion.
- Here, a radome for protecting the main board, the plurality of filters, and the plurality of antenna elements disposed by being stacked in the installation space of the antenna housing part may be installed on a front surface of the antenna housing part.
- Therefore, an antenna apparatus according to the related art is provided to dissipate most of driving heat generated from the predetermined heating elements mounted on the main board due to the provision of the radome rearward through a plurality of rear heat dissipation fins provided on a rear surface of the antenna housing part.
- However, in the antenna apparatus according to the related art, since the plurality of rear heat dissipation fins for dissipating system driving heat to a rear side of the antenna housing part should be formed at the rear side of the antenna housing part, a separation space for air circulation is needed between the rear heat dissipation fin and an installation wall surface, and thus there is a problem that production installation is restricted due to restriction to installation conditions or the like. In addition, in the antenna apparatus according to the related art, since the plurality of rear heat dissipation fins for dissipating the system driving heat to the rear side of the antenna housing part should be formed to integrally protrude rearward from the antenna housing part, an installation space as much as volumes of the rear heat dissipation fins is at least needed, and thus there is a problem of leading to installation restriction to installation wall surfaces of public facilities such as subways.
- In addition, even when the system driving heat of the antenna apparatus is dissipated to the front side of the antenna housing part, when the radome, which is an essential component for protecting the antenna element and the like, is provided, a heat dissipation area is restricted as much as an area of the radome, and thus there is a problem that an increase in heat dissipation performance is very restricted inevitably.

FIGS. 1 to 5 , theantenna housing part front housing 110 which is made of a thermally conductive material, formed in a shape of an enclosure having an open rear portion, has a predetermined installation space formed therein, and has a plurality of forwardheat dissipation fins 111 protruding to at least one side of a front surface thereof by a predetermined length and anelement seating part 115 in which anantenna element assembly 300 including a plurality of radiation elements is seated on a front surface from which some of the plurality of forwardheat dissipation fins 111 are removed provided flat, and therear housing cover 120 provided to shield the open rear portion of thefront housing 110. - Here, the main board 410 and the PSU board 420 may be disposed to be stacked in an installation space 110s of the
antenna housing part antenna housing part 110 and 120 (in particular, the front housing 110) provided with the plurality of forwardheat dissipation fins 111. - In addition, the plurality of
filters 500 may have a predetermined layer formed behind the main board 410 and the PSU board 420, and pass through between the main board 410 and the PSU board 420 and may be electrically connected to theantenna element assembly 300. - Although not illustrated, 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. In addition, generally, 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.
- However, since the above-described conventional arrangement structure necessarily requires the installation of the radome to protect the front of the antenna element assembly, which is the most important factor in the antenna apparatus, there has been a limitation that the intensive heat dissipation structure for the rear of the
antenna housing part - In order to solve the conventional problems at once, a technical feature of the antenna apparatus 100 according to one embodiment of the present disclosure is that the
