Antenna Bracket Assembly for Precise Radiation Angle Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless backhaul antennas face radio wave loss and inaccurate signal transmission due to inadequate antenna direction control.
Innovation Solution
An antenna assembly with a bracket that integrates with a strand wire, allowing for vertical and horizontal adjustment of the antenna direction without additional components, using joint parts and slots to guide the enclosure's rotation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna direction control is not implemented, then the structure remains simple, but radio wave loss increases and signal transmission accuracy decreases
Solution Approach 1:
The bracket integrates multiple functions: it serves as both the mounting structure for the antenna and the adjustment mechanism for directional control. The joint parts and slots are combined into a single integrated bracket structure that attaches to the strand wire while enabling enclosure rotation, eliminating the need for separate adjustment devices.
Solution Approach 2:
The bracket is designed as a multi-functional component that simultaneously provides structural support, mounting attachment to the strand wire, and rotational adjustment capability. The joint parts and slots serve dual purposes of mechanical connection and angular positioning, allowing one component to perform multiple functions.
2Reliability
If a separate adjustment device is added to control antenna direction, then signal transmission accuracy improves, but device complexity and number of components increase
Solution Approach 1:
The adjustment mechanism is merged with the mounting bracket. The joint parts and slots that form the adjustment mechanism are integrated directly into the bracket structure, eliminating the need for separate adjustment devices while maintaining full directional control capability.
Solution Approach 2:
The bracket serves as both the structural mounting component and the directional adjustment mechanism. By making the bracket multi-functional, the patent reduces the total component count while ensuring reliable antenna direction control through the integrated joint parts and slots system.

AI summary
A bracket includes a first member having one end joined to a first surface of an enclosure including an antenna, a second member having one end joined to a second surface of the enclosure, and a third member including a first slot joined to another end of the first member and a second slot joined to another end of the second member. In the bracket, the another end of the first member is guided along and moved in the first slot, and the another end of the second member is guided along and moved in the second slot.
