Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If traditional 4G antenna designs are used, then device compatibility is maintained, but communication speed and latency requirements for 5G services cannot be met
Solution Approach 1:
The antenna system is divided into multiple antenna elements arranged in arrays, with each element being a simplified magneto-electric dipole structure. This segmentation allows the system to achieve 5G performance through collective operation while keeping individual element design relatively simple and manufacturable.
Solution Approach 2:
The patent transitions from traditional planar antenna designs to three-dimensional magneto-electric dipole structures with vertical and horizontal components. This dimensional change enables broadband operation and high gain characteristics necessary for 5G while maintaining compatibility with PCB integration.
2Power
If directional antennas with narrow beam width are used, then high gain is achieved, but omnidirectional coverage is lost
Solution Approach 1:
The patent employs electronically controllable antenna arrays where the radiation pattern can be dynamically adjusted through phase and amplitude control of individual elements. This allows the system to switch between omnidirectional and directional patterns as needed, providing both high gain when required and versatile coverage when needed.
Solution Approach 2:
The magneto-electric dipole antenna elements are designed to serve multiple functions: they can operate in both omnidirectional and directional modes, support multiple frequency bands, and provide both vertical and horizontal polarization. This multi-functionality resolves the contradiction between high gain and radiation pattern flexibility.
3Volume of moving object
If electrically small antennas are used, then device integration is improved, but radiation efficiency decreases
Solution Approach 1:
The patent uses composite magneto-electric dipole structures combining electric and magnetic resonant elements. This composite approach enables electrically small antennas to achieve enhanced radiation efficiency by utilizing both electric and magnetic currents, effectively overcoming the size-efficiency trade-off through synergistic interaction of different electromagnetic modes.
