Engineering Contradiction Analysis
1Productivity
If multiple antenna units are arranged in an array on the same substrate, then the antenna system can provide multiple signals simultaneously, but the signals from different antenna units have different amplitudes and phases that require correction
Solution Approach 1:
The patent divides the antenna system into independent antenna units, each with its own signal characteristics. By segmenting the array into individual measurable and correctable units, the system can address amplitude and phase differences in each unit separately, resolving the uniformity issue while maintaining high signal emission capacity
Solution Approach 2:
The patent changes the parameters (amplitude and phase) of signals from different antenna units through correction mechanisms. By adjusting these parameters to match a reference signal, the system achieves parameter uniformity across all antenna units while preserving their ability to emit multiple signals simultaneously
2Adaptability or versatility
If antenna signals with different amplitudes and phases are emitted by multiple antenna units, then the antenna array can operate independently, but the parameter differences must be corrected to ensure signal uniformity
Solution Approach 1:
The patent applies local quality by allowing each antenna unit to have its own signal characteristics initially, then applying localized correction to each unit's amplitude and phase parameters. This maintains the independence and adaptability of each unit while achieving overall signal uniformity through targeted parameter adjustments
3Manufacturing precision
If the parameters of antenna signals are corrected to be uniform, then signal consistency is improved, but the complexity of the correction system increases
Solution Approach 1:
The patent implements feedback by measuring the actual amplitude and phase parameters of each antenna unit's signal, comparing them against a reference, and using this information to drive correction mechanisms. This feedback loop achieves signal uniformity through a systematic correction process that manages system complexity effectively
4Measurement precision
If multiple signals are measured and corrected individually, then each signal's parameters can be optimized, but the measurement and correction process becomes more complex
Solution Approach 1:
The patent applies universality by using a standardized measurement and correction approach that can be applied to each antenna unit independently but follows the same procedural framework. This multi-functional methodology enables precise measurement and correction of multiple signals while managing system complexity through repetition of a proven process

AI summary
An antenna correcting system is provided. The antenna correction system compares amplitudes of antenna signals that are emitted or received respectively by a plurality of antenna units (AN1 to AN7) with each other to select one of the amplitudes as target amplitude. The antenna correction system corrects the amplitude of each of the antenna signals according to the target amplitude. As a result, the amplitudes of the antenna signals are the same as each other or approximate to each other. After the amplitudes of the antenna signals are corrected, the antenna correction system compares phases of the antenna signals with each other to select one of the phases as a target phase. The antenna correction system corrects the phase of each of the antenna signals according to the target phase. As a result, the phases of the antenna signals are the same as each other or approximate to each other.
