AI Technical Summary

Technical Problem

The antennas of existing smart home terminals need to be adjusted according to different locations and network conditions, but the structural design of the metal frame in the existing technology is cumbersome and costly.

Method used

The system employs a combination of a PCB tuning module and a side-locking bracket. The metal frame antenna is detachably connected, and the resonant frequency and impedance of the antenna are adjusted by a combination of shorting arms and connecting arms. Signal matching is optimized by combining a fifth-order LC matching network.

Benefits of technology

This technology enables flexible adjustment of the antenna under different metal frame structures, reduces manufacturing costs, and improves the antenna's radiation efficiency and signal matching effect.
