RELATED APPLICATION

The present application claims priority from and the benefit of Indian Patent Application No. 202121031276, filed Jul. 12, 2021, the disclosure of which is hereby incorporated herein by reference in full.

FIELD OF THE INVENTION

The present disclosure relates to communication systems and, in particular, to a mounting assembly for a base station antenna.

BACKGROUND OF THE INVENTION

The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s) for the present disclosure.

Cellular communications systems are used to provide wireless communications to fixed and mobile subscribers (herein “users”). A cellular communications system may include a plurality of base stations that each provide wireless cellular service for a specified coverage area that is typically referred to as a “cell”. Each base station may include one or more base station antennas that are used to transmit radio frequency (“RF”) signals to, and receive RF signals from, the users that are within the cell served by the base station. Base station antennas are directional devices that can concentrate the RF energy that is transmitted in certain directions (or received from those directions). A cellular base station antenna is a critical consideration in an efficient cellular network, particularly choosing the antenna with suitable physical characteristics for a specific application.

Typical base station antennas have large size and are bulky and heavy, therefore, such antennas require two or more mounting assemblies for mounting the base station antenna on a support structure, for example, a pole. Employing two or more mounting brackets increases an overall cost, including manufacturing cost, maintenance cost and assembly cost, for the base station antenna. The multiple mounting brackets are generally employed to provide support to the large and heavy base station antennas. The multiple mounting brackets generally include support brackets and tilt adjustment brackets. The multiple mounting brackets are connected at different lengths of the base station antennas. Furthermore, each mounting bracket connected to the base station antenna provides one dedicated function; for example, one or more brackets may be mounted at different lengths of the base station antenna provide only support to the base station antenna and an additional bracket is required to provide tilting operation of the base station antenna. Also, the operation for adjusting tilt angle of the base station antennas may be difficult and time-consuming.

In addition to the electronic steering of the antenna beam, base station antennas may be mechanically steered vertically in an elevation plane. Mechanical tilt to the base station antenna is used to reduce interference and/or coverage in a specific area and to concentrate coverage in a designated area. In a typical installation, the antenna is mounted to a support structure, such as a pole, by at least a pair of brackets. The mechanical tilt of the antenna is typically performed by pivoting the antenna about a horizontal axis defined by a first bracket using a second adjustable bracket mounted at different length of the base station antenna. One typical adjustable bracket comprises a scissor-style bracket. The scissor-style bracket is generally mounted near a top end cap of the base station antennas and is configured to provide tilt angle adjustment to base station antennas. However, the scissor style bracket does not provide sufficient strength to the heavy base station antennas and therefore, there is a requirement for mounting one or more additional brackets near a bottom end cap of the base station antennas, which in turn increases the overall cost of the base station antennas. Further, the scissor-style bracket does not provide up-tilt angle adjustment to the base station antenna.

More recently, base station antennas have been modified to have a compact structure by reducing size of radiating elements and other respective components assembled to the base station antennas. The reduction in size of base station antennas has reduced problems related to space constraint for mounting multiple antennas in a single support structure as well as the manufacturing cost of said base station antennas. However, the compact base station antennas are still attached to the support structure using two-point mount brackets as described above, for fixing the base station antennas with the support structure, wherein the first bracket is attached near a bottom end cap of the base station antenna providing support to the base station antenna, and the second bracket is a scissor-style bracket is attached near a top end cap of the base station antenna providing tilt adjustment to the base station antenna. The scissor action of the bracket also creates a potential pinch point for the installer. All of these issues are exacerbated when it is considered that the installation and adjustment of the antenna is often performed on antenna towers that are exposed to the elements and at significant elevations. Furthermore, said two-point mount brackets do not provide a sufficient up-tilt angle or down-tilt angle to the base station antennas which may be varied based on different installation sites, to reduce interference and/or coverage in a specific area and to concentrate coverage in a designated area. Said two-point mounting assembly is an over-design and expensive solution for mounting the base station antennas that have reduced length and are light in weight.

Accordingly, there remains a need of a mounting assembly for base station antennas having small length and less weight.

The intermediate member108may be integrally formed with the first clamp bracket of the pair of clamp brackets102. Although the exemplary configuration of the mounting assembly100, as disclosed and shown in the present disclosure, describes the intermediate member108defined as a U-shaped clamp, any other suitable structure may be utilized of the intermediate member108to pivotably connect the intermediate member108with the mounting bracket104. The intermediate member108comprises a third pair of flanges108aformed at opposite ends thereof. The intermediate member108is coupled to the mounting bracket104for supporting the mounting bracket104and also to facilitate the pivotal movement to the mounting bracket104, during adjustment in tilt angle of the antenna200. The intermediate member108is defined with provisions to pivotably couple the mounting bracket104by fasteners108band locking nuts108c.

The variation in diameter of the first portion and second portion of the lead screw106aprovides a step profile structure to the lead screw106aat the first end106f. The step-profile of the lead screw106alimits the movement of the adjustment bracket106dtowards the second end106sof the lead screw by abutting the adjustment bracket106dagainst the second portion106cof the lead screw106a.

Once again referring toFIGS.2-4, the lead screw106ais configured to engage with the threaded holes102hprovided on each of the first flange102gof the pair of clamp brackets102. The first portion106bof the lead screw106ais defined with a plurality of external threads adapted to rotatably engage with threads formed on holes102hof each of the first flange102g. The threaded engagement of the lead screw106awith each flange102gof the pair of clamp brackets102facilitates the transformation of rotational movement of the lead screw106ato a linear movement of the lead screw106a. The linear movement of the lead screw106aexerts a push/pull force onto the mounting bracket104, during the tilt angle adjustment of the antenna200.

The connecting pin106kis locked into a fixed position by inserting a cross-wire or cotter pin106minto a hole provided in the connecting pin106k. to the mounting bracket. The elongated slot104bon the mounting bracket104is configured to receive and guide the connecting pin106kof the adjustment bracket106d. The clockwise rotation of the lead screw106ainitiates a linear movement of the lead screw106atowards the mounting bracket104exerting a push force on the mounting bracket104by the connecting pin106k. The counter-clockwise rotation of the lead screw106ainitiates linear movement of the lead screw106aaway from the mounting bracket104exerting a pull force on the mounting bracket104by the connecting pin106k. The rotation of the lead screw106amoves the connecting pin106kwithin the elongated slot104dof the mounting bracket104for adjusting the tilt angle of the antenna200.

In another embodiment of the present disclosure a method for adjusting a tilt angle of an antenna200is disclosed. The antenna200is connected to a mounting bracket104of a mounting assembly100. The method comprises the step of: loosening of fasteners108badapted to connect the mounting bracket104with an intermediate member108. The method further comprises the step of: applying rotational movement to a lead screw106aconnecting the mounting bracket104with one of a pair of clamp brackets102, such that an adjustment bracket106dsecured to the lead screw106aexerts a push force or pull force onto the mounting bracket104to facilitate pivotal movement of the mounting bracket104around the fasteners108bfor adjusting a tilt angle of the antenna200with respect to the pair of clamp brackets102. The method further comprises: tightening the fasteners108bconnecting the mounting bracket104with the intermediate member108to secure the antenna200at a particular orientation.

The clockwise rotation of the lead screw106afacilitates pivotal movement of the antenna200in a down-tilt direction. The down-tilt direction is defined as a direction of movement of the antenna200when the bottom end cap portion of the antenna200bmoves towards the support structure300. The mounting assembly100provides at least 0-15° down tilt movement of the antenna200, but is not limited to the same. The counter clockwise rotation of the lead screw106afacilitates pivotal movement of the antenna200in an up-tilt direction. The up-tilt direction is defined as a direction of movement of the antenna200when the bottom end cap portion of the antenna200bmoves away from the support structure300. The mounting assembly100provides at least 0-5° up-tilt movement of the antenna200, but not limited to the same.

The antenna200may comprise a bumper element fixed at the bottom end cap200bof the antenna200to prevent damage caused to the antenna200during excess angular movement of antenna200.
