Multi-Antenna Mounting Device Synchronous Tilt Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-antenna systems lack the ability to synchronously adjust the mechanical tilt angles of base station antennas, which is crucial for optimal wireless communication network coverage, especially in 4G and 5G networks where multiple antennas need to cooperate effectively.
Innovation Solution
A multi-antenna mounting device with a tilt angle adjusting mechanism comprising an upper and lower adjusting component, allowing for synchronous adjustment of mechanical tilt angles between -5° and +5°, utilizing a plate-shaped upper adjusting component with tilt angle holes and a pivotable lower section to accommodate different tilt angles relative to a user's support pole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple base station antennas are mounted together on a support pole, then the wireless communication network coverage can be improved through cooperative transmission, but the mechanical tilt angles of the antennas cannot be adjusted synchronously
Solution Approach 1:
The patent combines multiple antenna mounting functions and tilt angle adjustment functions into a single integrated mounting device. The mounting member includes a clamp for securing to the support pole and an adjustable platform that can tilt the entire multi-antenna assembly synchronously, allowing all antennas to be adjusted together as one unit rather than individually
Solution Approach 2:
The mounting device serves multiple functions: it secures multiple different types of base station antennas to the support pole, provides synchronous tilt angle adjustment for all antennas, and allows individual antenna positioning. The adjustable platform can tilt in multiple directions and the clamp can accommodate various pole diameters, making the device universally applicable to different antenna configurations
2Device complexity
If base station antennas are directly fixed to the support pole, then the mounting structure is simple, but the attitudes of the antennas cannot be adjusted
Solution Approach 1:
The mounting device transitions from a static direct-fixation structure to a dynamic adjustable structure. The platform includes tilt adjustment mechanisms with movable components that can change the angle of the mounted antennas relative to the support pole, allowing the system to adapt to different coverage requirements while maintaining structural integrity
3Ease of operation
If separate adjustment mechanisms are provided for each antenna, then individual attitude adjustment is possible, but the device complexity increases
Solution Approach 1:
Instead of providing separate adjustment mechanisms for each antenna, the patent merges the adjustment functionality into a single platform that supports multiple antennas. The tilt adjustment mechanism is integrated at the platform level, allowing synchronous adjustment of all mounted antennas through one set of adjustment components rather than requiring individual mechanisms for each antenna

AI summary
A multi-antenna mounting device includes: a mounting member to which two or more antennas are fixable; and a tilt angle adjusting mechanism including an upper adjusting component and a lower adjusting component spaced apart along a length direction of the mounting member. The upper adjusting component includes a plurality of tilt angle adjusting holes arranged in a row, one end of the upper adjusting component is connectable to the mounting member, and the other end is connectable to a user's support pole with a fastening element extending through one of the tilt angle adjusting holes. When the fastening element extends through different tilt angle adjusting holes, the multi-antenna assembly has different mechanical tilt angles relative to the support pole. The lower adjusting component includes a first section and a second section. The second section has a predetermined length and the first section is pivotable relative to the second section.
