Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the number of antennas is increased for fast data transmission in 5G communication, then data transmission speed is improved, but the design space is reduced and radiation efficiency becomes difficult to secure
Solution Approach 1:
The patent transitions from conventional planar antenna layouts to a three-dimensional configuration by positioning antennas on different surfaces (front surface and side surface) of the electronic device. This spatial dimensionality change allows multiple antennas to be arranged without occupying excessive planar area, thereby maintaining design space while supporting multiple antennas for high-speed data transmission
2Speed
If the number of antennas is increased for fast data transmission in 5G communication, then data transmission speed is improved, but radiation efficiency becomes difficult to secure
Solution Approach 1:
The patent applies different structural configurations to different antennas based on their specific locations and functions. The first antenna on the front surface uses a metal pattern with specific geometric characteristics, while the second antenna on the side surface employs a different configuration. This localized optimization ensures that each antenna maintains high radiation efficiency despite the increased total number of antennas
3Area of stationary object
If a low-profile antenna with small size is designed, then antenna space utilization is improved, but arrangement freedom and radio performance optimization become more difficult
Solution Approach 1:
The patent divides the antenna system into multiple independent antenna units (first antenna on front surface, second antenna on side surface) that can be independently designed and positioned. Each segmented antenna unit maintains low profile characteristics while the overall system achieves high space utilization. This segmentation allows flexible arrangement across different device surfaces without compromising individual antenna performance
