The invention will be described below with reference to the accompanying drawings, which show embodiments of the invention. It should be understood, however, that the present invention may be embodied in many different forms and should not be construed as being limited to the specific embodiments set forth herein. Rather, the specific embodiments described below are intended to provide a more complete disclosure of the invention, so that others skilled in the art may fully understand the scope of the invention. It is also to be understood that the embodiments of the invention can be combined in various ways, thereby providing more additional embodiments.
It is to be understood that the terminology used in the description is for the purpose of describing particular embodiments only, and is not intended to be limiting of the invention. All terms used in the specification, including technical and scientific terms, unless defined otherwise, have the meanings commonly understood by those skilled in the art. Well-known functions or constructions may not be described in detail for brevity or clarity.
In the description, spatial relationships such as "upper", "lower", "above", "below", "top", "bottom", and the like may be used to describe one feature's relationship to another feature in the drawings. It will be understood that the spatial relationship terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, the systems shown in the figures are described substantially vertically, however they may also be inclined at a predetermined angle with respect to the ground, for example at 45 ° overall.
Fig. 1A and 1B are a perspective view and a side view of an antenna mounting device and a base station antenna system in an installation state, the base station antenna system including the antenna mounting device according to an embodiment of the present invention. Fig. 2A and 2B are a perspective view and a side view of the antenna mounting device and the base station antenna system of fig. 1A and 1B in another mounting state. The two installation states differ substantially in the common mechanical tilt angle of the base station antennas 20, 30, wherein in the installation state shown in fig. 1A and 1B the base station antennas are tilted at an angle towards the ground, and in the installation state shown in fig. 2A and 2B the base station antennas are not tilted towards the ground but are substantially parallel to the mast-formed infrastructure 10 or substantially parallel to the ground.
The base station antenna system comprises two base station antennas 20, 30, which are arranged one after the other in the longitudinal direction. It goes without saying that it is also possible for more base station antennas to be arranged one behind the other in the longitudinal direction, or that further base station antennas can be additionally arranged next to the two base station antennas 20, 30 arranged one behind the other.
The antenna mounting device comprises a mounting frame 1 having a first side and a second side opposite to the first side. The mounting frame 1 may comprise two longitudinal beams 11 spaced apart from each other and a plurality of cross beams 12 connecting the longitudinal beams. The mounting frame 1 is designed for the fixing of two base station antennas 20, 30 on a first side, which extend over the longitudinal extent of the mounting frame. The mounting frame 1 is also configured for being fastened on a second side to an infrastructure 10, for example a communication tower or a pole, by means of fastening means 2 spaced apart from each other over the longitudinal extension of the mounting frame.
As shown in fig. 1 and 3, an adjusting element 3 is provided between the uppermost first fastening means and the mounting frame 1, by means of which adjusting element the distance between the mounting frame 1 and the first fastening means can be adjusted, so that the mounting frame has an adjustable mechanical tilt and thus the mechanical tilt of the base station antennas can be adjusted jointly.
As shown in fig. 1 and 3, the adjustment member 3 has a pair of arms each having a plurality of mounting holes 13 arranged in a row, and the first fastening mechanism is mountable between the pair of arms by means of each of the mounting holes 13 of the pair of arms. By fixing the first fastening means in different mounting holes 13, the distance between the first fastening means and the mounting frame can be adjusted and thus the mechanical tilt angle of the mounting frame can be changed.
As shown in fig. 1 and 5, a second, lowermost fastening mechanism is directly connected to the mounting frame. The second fastening means can provide a pivot point for the mounting frame 1, wherein a pivoting of the base station antennas together with the mounting frame about the pivot point and thus a joint adjustment of the mechanical tilt angle can be achieved in a simple manner by changing the mounting position of the first fastening means on the adjusting member 3.
In a not shown embodiment, the second fastening device can also be assigned a further identical or similar adjustment element. Thus, a more flexible adjustment of the mechanical tilt angle can be achieved by the combination of the two adjustment members.
In an embodiment not shown, the first and second fastening mechanisms as shown in fig. 1 may be interchanged.
Advantageously, as shown in fig. 1 and 4, the antenna mounting device may further include a third fastening mechanism between the first fastening mechanism and the second fastening mechanism, the third fastening mechanism being connected to the mounting frame by a movement limiting member 4 configured to limit a range of movement of the mounting frame.
As shown in fig. 1 and 4, the movement restricting member 4 may have a pair of arms, each of which has a long hole 14, and the second fastening mechanism is provided between the pair of arms of the movement restricting member and has a pin 15 guided in the long holes. The elongated hole 14 may limit the range of movement of the pin 15 and thus the second fastening mechanism. For example, when the first fastening means is released from connection to the adjustment element 3, tilting of the base station antennas 20, 30 together with the mounting frame 1 can be prevented simply by the movement limiting element 4, and subsequently the first fastening means can be easily reconnected to the adjustment element 3.
In the installation state shown in fig. 1A and 1B, the pin 15 rests on an end region of the elongated hole 14 facing the pole, and in the installation state shown in fig. 2A and 2B, the pin 15 rests on an end region of the elongated hole 14 facing the mounting frame.
As the fastening mechanism 2, a fastening mechanism widely used in the related art may be adopted, or a suitable fastening mechanism may be specifically designed according to the configuration of a specific infrastructure 10. In the embodiment shown, each fastening mechanism 2 comprises a pair of jaws which are fastened to the mast by a bolt connection. Alternatively, a metal clip can be used, which can comprise two substantially semicircular components which are hinged to one another in their one end region and can be detachably connected to one another in their other end region.
Advantageously, the antenna mounting means may have a fixing means 5 for each base station antenna 20, 30. It is also possible, for example, for the two base station antennas 20, 30 to be firmly fixed to one another and only one of the base station antennas to be connected to the mounting frame 1 by means of the fixing device 5.
Exemplary embodiments of the present invention are described above with reference to the accompanying drawings. However, those skilled in the art will appreciate that various modifications and changes can be made to the exemplary embodiments of the present invention without departing from the spirit and scope of the invention. All such variations and modifications are intended to be included herein within the scope of this disclosure.
