Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing antenna devices are used, then the device structure is simple, but the ability to modulate phase, bandwidth, intensity, or polarization state of electromagnetic waves is insufficient
Solution Approach 1:
The antenna device is divided into multiple modulation units, each capable of independent voltage control. Each modulation unit includes electronic elements (such as varactor diodes or transistors) that can be individually regulated by control voltages applied through signal lines, enabling separate control of different antenna regions to achieve phase, bandwidth, intensity, or polarization modulation.
Solution Approach 2:
The antenna device incorporates electronically controllable elements whose electrical characteristics (capacitance, resistance, conductivity) can be dynamically changed by applying different voltages. This allows the antenna to adapt its electromagnetic properties in real-time, providing dynamic modulation capabilities for phase, bandwidth, intensity, and polarization state without physical reconfiguration.
2Productivity
If multiple modulation units with multiple voltage signals are implemented, then the modulation effectiveness is improved, but the control complexity increases
Solution Approach 1:
The modulation units are designed with universal control mechanisms where similar electronic elements and signal line configurations can achieve multiple modulation functions (phase, bandwidth, intensity, polarization). This standardized approach reduces control complexity by using repeatable modular units rather than specialized components for each modulation type.
Solution Approach 2:
The device modulates electromagnetic waves by changing electrical parameters (voltage, capacitance, conductivity) of the electronic elements within modulation units. By controlling parameters such as the capacitance value of varactor diodes or the conductivity of transistors through applied voltages, the antenna achieves effective modulation of phase, bandwidth, intensity, and polarization state through parameter variation rather than structural reconfiguration.

AI summary
An electronic device, including a substrate and multiple modulation units, is provided. The modulation units are disposed on the substrate. Each modulation unit includes a first electronic element, a second electronic element, a first signal line, a second signal line, and a third signal line. The first signal line provides a first voltage to the first electronic element. The second signal line provides a second voltage to the second electronic element. The third signal line provides a third voltage to the first electronic element and/or the second electronic element. The first voltage is different from the second voltage, and the third voltage is different from the first voltage and/or the second voltage.
