Abstract

An antenna device according to one of various examples of the present invention can comprise: an antenna module; a radio remote head (RRH) for receiving signals from the antenna module and a base station; guide modules for guiding the RRH such that the RRH slidably moves in an inclined state in the antenna module, for providing one end portion of the RRH to be rotated, and for providing the other end portion of the RRH to move vertically in the sliding movement direction; connection modules provided on a surface on which the antenna module and the RRH face each other, and electrically connecting the RRH and the antenna module; and coupling modules provided on one side of the RRH so as to move the connection modules, thereby mutually coupling or separating the connection modules.

First claim

The invention claimed is:

1. An antenna device comprising: an antenna module;
a radio remote head (RRH) configured to receive signals from the antenna module and a base station;
an attachment/detachment member configured to attach/detach the RRH to/from one surface of the antenna module;
connection modules provided on a surface on which the antenna module and the RRH face each other to electrically connect the RRH and the antenna module to each other; and
coupling modules provided on one surface of the RRH to move the connection modules so that the connection modules are coupled to or separated from each other;
wherein the attachment/detachment member is provided on upper and lower portions of the antenna module and the RRH as guide modules configured to slidably guide the RRH on the antenna module, to cause one end portion of the RRH to be rotatably seated, and to cause the other end portion of the RRH to be seated to be movable toward the antenna module.

2. The antenna device of claim 1 , wherein the guide module comprises:
an upper end rail portion provided on an upper portion of the antenna module and coupled to one end portion of the RRH to form a circular hollow portion in a sliding direction so as to slidably move and rotatably support the one end portion of the RRH;
an upper end slider provided on an upper portion of the RRH, formed in a bar shape in the sliding movement direction, and seated on the upper end rail portion to slidably move along the first guide module or to be rotated on the first guide module;
a lower end rail portion provided on a lower portion of the antenna module, and coupled to the other end portion of the RRH to slidably move the other end portion of the RRH and to movably support the RRH in a direction in which the RRH gets adjacent to or goes away from the antenna module about the one end portion of the RRH as a rotation axis; and
a lower end slider provided on a lower portion of the RRH, and seated on a second guide portion to slidably move along the second guide portion or to move in a vertical direction to a sliding movement direction.

3. The antenna device of claim 2 , wherein the lower end rail portion comprises a first-direction guide groove having the sliding movement direction and a second-direction guide groove having the vertical direction to the sliding movement direction, and
the lower end slider is formed to project from at least one of the lower portion of the RRH and a lower portion of the connection module to slidably move along the first-direction guide groove and the second-direction guide groove.

4. The antenna device of claim 3 , wherein the RRH slidably moves in the form of a slant line in a direction that is measured from one side to the other side of the antenna module, and then is coupled to the antenna module through pushing of the lower portion of the RRH toward the antenna module.

5. The antenna device of claim 4 , wherein the upper end rail portion is seated on the upper end slider, the lower end rail portion is seated in the first-direction guide groove, and the RRH slidably moves to a rear surface of the antenna module in the form of a slant line in the direction that is measured from the one side to the other side of the antenna module, and
the lower end slider moves along the second-direction guide groove, the upper end slider is rotated on the upper end rail portion, and the RRH is coupled to the rear surface of the antenna module.

6. The antenna device of claim 1 , wherein the coupling module comprises:
a locking plate provided on a rear surface of the antenna module, provided with a hook-shaped opening, and detachably coupling and fixing the other end portion of the RRH in at least one of automatic and manual manners; and
a locking projection provided to project in a side surface direction from a front surface of the RRH to be locked in or unlocked from the opening of the locking plate.

7. The antenna device of claim 1 , wherein the connection module has a blind mating structure, and comprises:
a first connection portion formed to project from a rear surface of the antenna module; and
a second connection portion provided on the RRH and positioned to face the first connection portion to be elastically engaged with the first connection portion in accordance with a movement in a direction that is vertical to a sliding movement direction of the other end portion of the RRH.

8. The antenna device of claim 7 , wherein the coupling module comprises:
a lever portion provided in an opening that is provided on a rear surface of the second connection portion; and
a movement portion configured to move the second connection portion so that the second connection portion is electrically coupled to the first connection portion in accordance with a rotation of the lever portion.

9. The antenna device of claim 8 , wherein the coupling module comprises a locking mode in which the lever portion is seated in the opening to limit a movement of the second connection portion, and a driving mode in which the lever portion secedes from the opening and is rotated to move the second connection portion in a direction in which the second connection portion goes away from or gets near to the first connection portion so that the second connection potion is electrically attached to or detached from the first connection portion.

10. The antenna device of claim 9 , wherein the first connection portion and the second connection portion push or pull the other end portion of the RRH in a direction in which the other end portion of the RRH moves to get near to or to go away from the antenna module to cause the other end portion of the RRH to be seated on the antenna module, and
the first connection portion moves along the movement portion in accordance with rotation driving of the lever portion to be electrically attached to or detached from the second connection portion.

11. An antenna device comprising: an antenna module;
a radio remote head (RRH) configured to receive signals from the antenna module and a base station;
an attachment/detachment member configured to attach/detach the RRH to/from one surface of the antenna module;
connection modules provided on a surface on which the antenna module and the RRH face each other to electrically connect the RRH and the antenna module to each other; and
coupling modules provided on one surface of the RRH to move the connection modules so that the connection modules are coupled to or separated from each other;
wherein the attachment/detachment member is provided on upper and lower portions of the antenna module and the RRH as guide modules configured to cause one end portion of the RRH to be locked and rotatably seated, to guide the other end portion of the RRH to move in a direction in which the other end portion of the RRH gets near to or goes away from the antenna module in accordance with rotation of the RRH, and to cause the other end portion of the RRH to be seated.

12. The antenna device of claim 11 , wherein the guide module comprises:
at least one locking bar member provided on an upper side of the antenna module to cause the one end portion of the RRH to be rotatably locked and seated;
at least one hook member provided on an upper portion of the RRH to be rotatably locked and seated on the locking bar member;
a lower end rail portion provided on a lower portion of the antenna module, and coupled to the other end portion of the RRH to guide and support the other end portion of the RRH to move in a direction in which the other end portion of the RRH gets adjacent to or goes away from the antenna module about the one end portion of the RRH as a rotation axis; and
a low
