Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional all-in-one design integrates passive components, beamforming chips, and antennas into a single unit system, then system integration is achieved, but device complexity and maintenance cost increase significantly
Solution Approach 1:
The patent divides the conventional all-in-one array antenna system into separate functional modules: passive components (capacitors, resistors), beamforming chips (power amplifiers, phase shifters, low-noise amplifiers), and antenna elements. Each module is independently packaged and can be separately replaced or maintained, reducing overall system complexity while maintaining integration benefits.
2Stability of the object's composition
If conventional all-in-one design integrates all components into a single unit, then system integration is achieved, but maintenance cost increases due to inability to replace individual faulty components
Solution Approach 1:
The system is segmented into replaceable modules where individual faulty components (such as a single power amplifier or phase shifter) can be identified and replaced without replacing the entire array antenna system. This modular approach significantly reduces maintenance costs and downtime.
Solution Approach 2:
The patent enables selective replacement of degraded or faulty components while retaining functional modules. Used modules can be recovered, refurbished, and reused, reducing waste and maintenance costs associated with replacing entire systems.
3Adaptability or versatility
If large-scale array antennas are fabricated to meet different antenna gain requirements, then system adaptability improves, but fabrication cost and complexity increase with array physical size
Solution Approach 1:
The array antenna is divided into multiple identical or standardized modules that can be configured in different physical arrangements (e.g., linear arrays, planar arrays, volumetric arrays) to achieve various antenna gain patterns. This standardization reduces fabrication cost by reusing the same module designs across different applications.
Solution Approach 2:
The patent designs universal modules that can serve multiple functions and be deployed in various configurations to meet different antenna gain requirements. A single module type can be used in 1D, 2D, or 3D array configurations, providing adaptability without requiring custom fabrication for each application.
4Stability of the object's composition
If conventional design uses solid dielectric board for component mounting, then structural stability is maintained, but heat dissipation efficiency is insufficient for high-power RF applications
Solution Approach 1:
The patent replaces traditional solid dielectric boards with thin-film dielectric layers deposited on flexible or rigid substrates. These thin-film structures provide adequate electrical insulation and structural stability while allowing superior thermal conduction paths to efficiently dissipate heat from high-power RF components like power amplifiers.
Solution Approach 2:
The patent employs composite material structures combining dielectric layers with high-thermal-conductivity substrates or thermal interface materials. This composite approach maintains the electrical insulation properties required for RF operation while dramatically improving heat dissipation capability for high-power applications.

AI summary
An arrayed RF system includes an expandable mother circuit carrier and sub-modules implemented with RF packaged radiation structures. The sub-modules are embedded onto the mother circuit carrier through plug-in interfaces to form a replaceable and expandable co-structural structure. The mother circuit carrier receives and up-converts an input intermediate-frequency signal, thereby generating first high-frequency signals. The sub-modules are horizontally embedded on the mother circuit carrier, arranged into a one-dimensional or two-dimensional array, and electrically connected to the mother circuit carrier. The RF packaged radiation structures respectively receive first high-frequency signals, thereby emitting first RF signals. The RF packaged radiation structures receive second RF signals, thereby generating second high-frequency signals. The mother circuit carrier down-converts the second high-frequency signals, thereby generating an output intermediate-frequency signal.
