Mobile Terminal Antenna Selection via Pressure Sensors

The patent implements dynamic antenna selection based on real-time pressure sensor feedback. The processor continuously monitors pressure values from sensors and dynamically switches between different antennas depending on which one is not covered by the user's hand. This dynamic adaptation resolves the contradiction by making the antenna system flexible rather than static, maintaining reliability without requiring all antennas to be actively managed simultaneously.

The system uses pressure sensors to automatically detect user hand coverage and self-adjust antenna selection without user intervention. The processor autonomously determines which antenna is blocked and switches to an uncovered antenna, making the system self-regulating. This reduces the operational complexity of managing multiple antennas while maintaining signal reliability.

The patent introduces pressure sensors as intermediary detection devices that indirectly sense hand coverage through pressure changes on the housing surface. Rather than directly detecting antenna blockage, the sensors measure pressure at contact points, which the processor then correlates with antenna coverage status. This intermediary approach reduces the complexity of direct antenna monitoring while effectively detecting harmful hand coverage.

The patent replaces direct mechanical or visual detection of antenna coverage with pressure-sensitive detection. Instead of complex mechanisms to determine hand position, simple pressure sensors measure force applied to the housing, and the processor translates this mechanical input into antenna selection decisions. This substitution reduces system complexity while maintaining effective interference avoidance.
