Engineering Contradiction Analysis
1Volume of moving object
If the transmitting power is increased to enlarge the signal radiation range, then the signal radiation range is improved, but the power consumption increases and heat dissipation becomes difficult
Solution Approach 1:
The patent extracts the power amplification function from the mobile terminal and places it in an external active antenna system. This separates the high-power transmission component from the terminal device, allowing the terminal to maintain low power consumption while the external antenna handles high-power signal amplification to extend radiation range.
Solution Approach 2:
The antenna system is segmented into multiple functional modules: the mobile terminal, the active antenna unit with power amplifier, and the antenna element. This modular segmentation allows independent optimization of each component, with the power amplifier dedicated to signal boosting and the terminal focused on baseband processing, reducing overall system power consumption.
2Volume of moving object
If the transmitting power is increased to enlarge the signal radiation range, then the signal radiation range is improved, but the heat dissipation becomes difficult causing terminal overheating
Solution Approach 1:
The heat-generating power amplification function is extracted from the mobile terminal and relocated to an external active antenna system. This physical separation removes the primary heat source from the terminal device, preventing overheating while maintaining the ability to transmit at high power levels through the external antenna.
3Volume of moving object
If the terminal volume is reduced for miniaturization, then the portability is improved, but the heat dissipation capability deteriorates
Solution Approach 1:
The heat-generating power amplification function is extracted from the mobile terminal and relocated to an external active antenna system. This physical separation removes the primary heat source from the terminal device, preventing overheating while maintaining the ability to transmit at high power levels through the external antenna.
