Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a non-directional antenna is used, then radiation is performed in all directions, but gain in a specific direction is low
Solution Approach 1:
The antenna is divided into two separate radiators: a Z-directional radiator for vertical radiation and an XY-directional radiator for horizontal radiation. Each radiator is optimized for its specific directional characteristics, allowing the system to achieve both broad coverage and high gain in specific directions by combining their effects.
2Power
If a directional antenna is used, then gain in a specific direction is high, but beam width is narrow and shadow region is broad
Solution Approach 1:
The patent combines a Z-directional radiator and an XY-directional radiator into a single antenna system. The Z-directional radiator provides high gain in the vertical direction, while the XY-directional radiator provides broad horizontal coverage. Their combined radiation patterns create a three-dimensional coverage pattern that maintains high gain while expanding the effective coverage area.
3Reliability
If both directionality and non-directionality are achieved, then communication sensitivity is improved, but device complexity increases
Solution Approach 1:
An induction coupler is introduced as an intermediary component between the Z-directional radiator and the XY-directional radiator. This coupler enables electromagnetic energy transfer between the two radiators, allowing them to work cooperatively to achieve both directionality and non-directionality. The induction coupler simplifies the overall structure compared to using completely separate antenna systems.
