Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple antennas are placed on the same region of the dielectric element, then the device complexity is reduced, but the antenna gain and signal transmission performance deteriorate due to interference and limited space
Solution Approach 1:
The patent transitions from planar antenna arrangement to three-dimensional spatial distribution by placing antennas on different surfaces and regions of the dielectric element. The first antenna is on the first surface while the second antenna is on the second surface, utilizing the third dimension (depth/thickness) to separate antenna positions and reduce interference while maintaining a compact overall structure.
Solution Approach 2:
The dielectric element is divided into distinct regions (first region and second region) with different antenna gain characteristics. Each region is optimized for specific frequency bands, allowing segmented functional allocation that improves overall multi-band performance while maintaining manageable device complexity.
2Manufacturing precision
If antennas are aligned in the same position, then the manufacturing precision is improved, but the multi-band performance deteriorates due to frequency interference and limited optimization capability
Solution Approach 1:
Different regions of the dielectric element are designed with distinct electromagnetic properties and antenna gain characteristics. The first region provides different gain characteristics than the second region, allowing each antenna to be locally optimized for its specific frequency band while maintaining precise manufacturing alignment.
3Device complexity
If a single antenna is used for multiple frequency bands, then the device complexity is reduced, but the antenna gain and signal transmission loss deteriorate due to compromised optimization for each band
Solution Approach 1:
The dielectric element itself serves multiple functions: it provides structural support, electromagnetic isolation between antennas, and gain enhancement for multiple frequency bands simultaneously. This universal component approach reduces overall device complexity while enabling multi-band operation with optimized performance for each band through the misaligned multi-antenna configuration.
