A base station antenna device includes an antenna module having a separation space spaced a predetermined distance forward from a support pole, a remote radio head (RRH) provided on the rear surface of the antenna module such that the RRH is slidably assembled in a detachable manner in a horizontal direction from a lateral side of the separation space, and an adapter having a push block provided on a lower end portion of the RRH so as to mediate the electrical signal connection and disconnection between the antenna module and the RRH by means of a pushing operation in the longitudinal direction.

Base station antenna device and adapter thereof

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.

Antenna device

The present disclosure relates to an antenna apparatus for a base station and an adapter thereof and particularly comprises: an antenna module vertically installed to be spaced forward from a support pole by a predetermined distance so as to have a distancing space therebetween; an RRH installed on the antenna module to be positioned in the distancing space, wherein one of the upper end and the lower end thereof is hinge-coupled to the antenna module and the other of the upper end and the lower end thereof is attached to or detached from a part of the antenna module to enable electrical signal connection or disconnection while being rotated around the hinge; and an adapter for mediating the electrical signal connection and disconnection between the antenna module and the RRH. Therefore, the present disclosure provides advantages of reducing installation time and installation costs.

Antenna apparatus for base station and adapter thereof

The present invention relates to an antenna device, comprising: a front housing including antenna arrangement units in which at least one radiation element is disposed on the front sides thereof, and heat dissipation units formed between adjacent antenna arrangement units and being exposed to outside air to transfer heat generated from the rear side to the front; and a rear housing coupled to the front housing and provided with a filter for filtering RF signals and a main board on which an RF element is mounted, wherein the heat generated from the filter is transferred to the front of the front housing through the contact with the back surface of the front housing by using the filter as a heat transfer medium.

A clamping apparatus for an antenna includes: an arm unit coupled to a support pole and extending in one horizontal direction from the support pole by a predetermined distance; a common coupling unit detachably mounted to a front end of the arm unit by insertion and detachment operations of a coupling shaft elongated vertically, the common coupling unit being selectively rotatable from side to side about the coupling shaft; a rotation unit having a front end detachably mounted to a front end of the coupling unit by insertion and detachment operations of a rotary shaft elongated vertically, the rotation unit being rotatable from side to side by a predetermined angle about the rotary shaft; and a tilting unit coupled to the front end of the rotation unit to be tiltable vertically, an antenna device being coupled to the tilting unit.

Clamping apparatus for antenna
