Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the antenna is extended to receive GPS L5 signal, then GNSS multi-band reception capability is improved, but reception performance for wireless communication signal decreases
Solution Approach 1:
The antenna structure is divided into two separate conductive regions (first conductive region and second conductive region) that are electrically isolated from each other. The first conductive region is dedicated to GPS L1 and L5 signals, while the second conductive region handles wireless communication signals and GPS L1 signals. This segmentation allows each region to be optimized for its specific function without interference from the other, resolving the contradiction between multi-band GNSS reception and wireless communication performance.
2Adaptability or versatility
If the antenna is connected with receiver circuitry for GPS L1 and L5 signals, then GNSS multi-band reception capability is improved, but reception performance for GPS L5 signal decreases
Solution Approach 1:
The antenna system is segmented into two independent conductive regions with separate connection paths to the receiver circuitry. The first conductive region connects to the GNSS receiver for L1 and L5 signals, while the second conductive region connects to both wireless communication circuitry and the GNSS receiver. This segmentation eliminates signal interference and impedance mismatches that would occur with a shared connection, ensuring optimal GPS L5 signal reception while maintaining multi-band capability.
3Device complexity
If a single antenna structure is used for both wireless communication and GNSS signals, then device complexity is reduced, but signal reception performance for both GNSS and wireless communication signals decreases
Solution Approach 1:
Instead of using a single antenna structure, the patent implements two separate conductive regions that are electrically isolated. This segmentation, while slightly increasing structural complexity, ensures that wireless communication signals and GNSS signals do not interfere with each other, thereby maintaining high reception performance for both signal types.
Solution Approach 2:
The first conductive region serves multiple functions by handling both GPS L1 and L5 signals, while the second conductive region handles wireless communication signals and GPS L1 signals. This multi-functionality approach allows the antenna system to support multiple signal types with separate optimized paths, resolving the contradiction between simplicity and performance.
