Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face inefficiencies in adaptive antenna beam-forming due to the limitations of microstrip planar Butler matrices, which lead to increased structural size, energy attenuation, and cost-ineffectiveness, as well as reliance on trigonometric positioning methods that result in a 'window period' of waiting time for beam adjustment, failing to meet user needs for real-time signal tracking.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a microstrip planar Butler matrix is used for beam adjustment, then the beam can be directed to specific positions, but the structural size increases and integration with array antenna becomes difficult
Solution Approach 1:
The patent extracts the complex passive Butler matrix network from the system and replaces it with a simplified active phase adjustment circuit integrated directly with the array antenna. This removal of the bulky passive network resolves the contradiction by maintaining beam positioning capability while dramatically reducing structural size and integration difficulty.
Solution Approach 2:
The patent replaces the mechanical/passive Butler matrix structure with an electronic active phase adjustment system. This substitution eliminates the need for complex physical transmission line arrangements while achieving the same beam directing function, thereby reducing structural complexity.
2Measurement precision
If a microstrip planar Butler matrix is used for phase adjustment, then beam direction can be controlled, but energy attenuation in the circuit substrate increases
Solution Approach 1:
The patent removes the energy-attenuating passive Butler matrix network from the signal path and replaces it with an active phase adjustment circuit that operates with lower loss. This extraction eliminates the source of energy attenuation while preserving phase control functionality.
Solution Approach 2:
The patent substitutes the passive electromagnetic network with an active electronic control system that can adjust phase dynamically with minimal energy loss, resolving the contradiction between phase control accuracy and energy attenuation.
3Measurement precision
If trigonometric positioning method is used for user positioning, then beam can be directed to user position, but a waiting time period (window period) occurs during signal transmission
Solution Approach 1:
The patent implements preliminary action by continuously tracking user position in real-time rather than waiting for periodic positioning updates. The system proactively monitors and adjusts beam direction based on continuous position data, eliminating the waiting time period while maintaining positioning accuracy.
Solution Approach 2:
The patent transitions from static periodic positioning to dynamic continuous tracking. The beam-forming system dynamically adjusts to real-time position changes without interruption, resolving the contradiction between position accuracy and transmission time loss.
4Productivity
If conventional beam-forming methods are used, then signal can be transmitted to user device, but processing efficiency is low and user needs are not met
Solution Approach 1:
The patent replaces conventional passive beam-forming methods with an active intelligent beam-tracking system that uses real-time position data and adaptive algorithms. This substitution dramatically improves processing efficiency by eliminating waiting periods and enabling continuous signal transmission.
Solution Approach 2:
The patent ensures continuous useful action by maintaining uninterrupted beam tracking and signal transmission. The system continuously adjusts beam direction based on real-time position feedback, eliminating idle window periods and maximizing transmission efficiency.
