Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an antenna supporting apparatus, and more particularly, to an antenna holder and a supporting apparatus which are designed to be fixed by arbitrarily adjusting the direction and angle of an antenna.
A so-called sector antenna having directionality and directivity, which is installed in a mobile communication base station, has components and their arrangement for maximizing the propagation distance or beam titration, and is a means for installing a directional antenna There is a need for a supporting device capable of appropriately adjusting the tilt angle of the antenna.
A number of devices having this object have been proposed, basically including upper and lower brackets, the technical features of which are primarily related to the upper bracket.
The bracket structure in this field generally includes:
First, a structure having a "V" -shaped link member whose both joints are angled as they expand and contract about an intermediate axis, such as in an antenna fixture disclosed in U.S. Utility Model Publication No. 2010-12684;
A structure having a linear link member that is angularly adjusted as one arm is rotatably connected to both shafts, as in the antenna angle adjusting device disclosed in Japanese Laid-Open Patent Publication No. 2003-69260;
.

The lower portion is only attached to the
The upper portion is connected to the
Respectively.
Here, a fixing piece 108 through which the
Specifically, the antenna A is configured such that the end of the
It is true that such an angle adjustment is quite effective for a sector antenna. However, in this bracket or supporting structure, the installed antenna itself can not be rotated, and therefore the direction of the antenna can not be changed. In fact, in a high gain polarized antenna, the polarization (rotation) variable can be an important factor for determining the efficiency or the characteristic as well as the tilt (gradient) variation above.
However, in the above example, there is no mention of polarization variation, and there is a problem that is impossible at all in terms of structure.
The present invention has been proposed to solve the problems of the above-mentioned prior arts. It is an object of the present invention to provide an antenna holder capable of changing the direction of an antenna. Another object of the present invention is to provide an antenna supporting apparatus capable of both polarization variation and tilt change of an antenna by using the holder.
The antenna holder of the present invention comprises:
An outer ring-shaped or arc-shaped frame for providing a rotating frame;
An antenna grasping unit for grasping and holding the antenna body, the antenna grasping unit being rotatably provided inside the frame;
A fixing member for fixing the grip portion in the frame;
.
The grip portion is provided inside the frame in such a manner that at least left and right outer surfaces contact the inner wall of the frame. At this time, the left or right side includes the cutout portion, thereby enabling expansion and contraction of the inside space of the gripping portion.
The fixing member includes an engaging portion formed to protrude outward from the grip portion and to be pressed onto the edge of the frame. Preferably, the fastening member further comprises a plurality of recesses formed such that the fastening portions are correspondingly seated along corners of the frame.
Preferably, the gripping portion comprises:
A first grip portion and a second grip portion disposed on both sides of the frame;
Fastening means for bringing the first gripping portion and the second gripping portion in confrontation with each other;
The fastening member may include: a fastening part which is pressed onto the edge of the frame when tightly and fixes the fastening part to the frame;
.
The antenna support apparatus of the present invention comprises:
Upper and lower brackets spaced apart from each other on the upper and lower sides of the building;
The holder being configured to grip and hold the antenna body;
A support having an arm extending between the upper bracket and the holder and having both ends connected to the rotation axis;
An antenna receiving part connected to the lower bracket via a rotation shaft;
.
Preferably, the upper bracket includes a fixing base having a vertical slot, and the one-end rotation axis of the arm is configured to slide along the slot. Meanwhile, the receiving portion includes a plurality of fixing holes formed on the same radius around the shaft hole.
The antenna holder of the present invention comprises a frame for providing a rotating frame and an antenna holding portion rotatably provided inside the frame. Therefore, even if the frame is fixed to the outside, the direction of the antenna can be adjusted. In addition, the antenna supporting device of the present invention can adjust the inclination angle of the antenna by using an arm whose both ends are connected to each other via a rotation shaft. Therefore, according to the embodiment of the present invention, both of the polarization change due to the rotation of the antenna and the tilt change due to the tilt adjustment can be achieved easily.
