Phase Adjustment Device for Multi-Frequency Antenna
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost of multi-frequency antennas is attributed to the need for multiple driving apparatuses, each corresponding to a phase adjustment unit, which increases the overall cost and requires more space and time for installation due to the complexity of adjusting downtilt angles in existing electrical tilt mechanisms.
Innovation Solution
A phase adjustment apparatus with at least two phase adjustment units, a switching apparatus, and a driving apparatus, where the switching apparatus selectively connects only one phase adjustment unit to the driving apparatus at a time, allowing the driving apparatus to modulate the phases of multiple units using a single driving mechanism, thereby reducing the number of required driving apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a driving apparatus is configured for each phase adjustment unit in a multi-frequency antenna, then the downtilt angle of each antenna unit can be independently modulated, but the cost of the multi-frequency antenna increases due to the high cost of multiple driving apparatuses
Solution Approach 1:
One driving apparatus is designed to perform multiple functions by sequentially driving different phase adjustment units. The driving apparatus can be selectively connected to different phase adjustment units through a switching mechanism, allowing a single driving apparatus to replace multiple driving apparatuses while maintaining the capability to independently modulate each antenna unit's downtilt angle.
Solution Approach 2:
The connection between the driving apparatus and phase adjustment units is made dynamic through a switching mechanism. The switching apparatus can dynamically connect the driving apparatus to different phase adjustment units as needed, enabling flexible and adaptive control of different antenna units without requiring permanent dedicated driving apparatuses for each unit.
2Manufacturing precision
If multiple driving apparatuses are used for each phase adjustment unit, then precise control of downtilt angles is achieved, but the space required for installation increases
Solution Approach 1:
Multiple driving apparatuses are merged into a single driving apparatus that can sequentially serve different phase adjustment units. This consolidation reduces the total number of driving apparatuses from multiple to one, thereby reducing the installation space required while maintaining the precision control capability through sequential operation and switching mechanisms.
3Adaptability or versatility
If multiple driving apparatuses are configured for phase adjustment units, then each antenna unit can be adjusted independently, but the installation time increases due to complexity
Solution Approach 1:
A single multi-functional driving apparatus replaces multiple dedicated driving apparatuses, reducing the number of components that need to be installed and configured. The switching mechanism integrates the control of multiple phase adjustment units into one system, simplifying the installation process while preserving the independent adjustment capability of each antenna unit.
