Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single-frequency antenna structure is used, then the device complexity is reduced, but the adaptability to different frequency bands deteriorates
Solution Approach 1:
The patent combines multiple antenna types (patch antennas and dipole antennas) and multiple frequency band capabilities into a single integrated antenna module. The module includes first and second patch antenna groups for millimeter-wave frequencies and first and second dipole antenna groups for sub-6GHz frequencies, all integrated on one substrate. This merging approach enables multi-frequency band coverage while maintaining a unified structure, resolving the contradiction between adaptability and device complexity.
Solution Approach 2:
The antenna module is designed to perform multiple functions by supporting both millimeter-wave frequency bands (via patch antennas) and sub-6GHz frequency bands (via dipole antennas) within a single device. The modular design with multiple antenna groups allows the system to universally operate across different frequency ranges, achieving frequency band versatility without requiring separate dedicated antennas for each band.
2Reliability
If traditional antenna structures are used, then the manufacturing process is simple, but the radiation efficiency deteriorates
Solution Approach 1:
The patent employs a composite structure integrating different antenna technologies (patch and dipole antennas) on a single low-temperature co-fired ceramic (LTCC) substrate. This composite approach combines the high radiation efficiency of patch antennas for millimeter-wave frequencies with the proven performance of dipole antennas for sub-6GHz frequencies. The LTCC substrate provides excellent electrical properties and enables precise control of electromagnetic characteristics, achieving superior radiation efficiency while maintaining manufacturability through established ceramic processing techniques.
Solution Approach 2:
The patent utilizes a three-dimensional spatial arrangement of multiple antenna groups at different positions and orientations on the substrate. The first and second patch antenna groups are positioned at different locations to provide diverse radiation patterns, as are the dipole antenna groups. This spatial dimensionality optimization enhances radiation efficiency by reducing mutual interference and maximizing signal propagation in multiple directions, while the planar LTCC structure maintains ease of manufacturing.
3Adaptability or versatility
If multiple antenna groups are integrated, then the frequency band coverage is improved, but the device size increases
Solution Approach 1:
The patent implements a nested integration approach where multiple antenna groups (patch and dipole antennas) are embedded within a compact LTCC substrate structure. The antennas are arranged in overlapping and adjacent configurations that maximize space utilization. The dipole antenna groups are positioned to nest alongside the patch antenna groups, allowing multi-frequency band coverage to be achieved within a minimized footprint, effectively resolving the contradiction between frequency band coverage and device size.
