AI Technical Summary

Technical Problem

Due to the limited installation space in electronic devices and the need to support multiple communication systems, the individual installation and connection of antenna modules becomes difficult, and the isolation performance of antennas may be deteriorated, especially when different communication systems or frequency bands are used.

Method used

Flexible printed circuit board (FPCB) is used to connect antenna modules in different frequency bands to a single connection, and the noise caused by power transmission lines is reduced by designing a special FPCB structure.

Benefits of technology

It realizes the efficient connection of antenna modules of different frequency bands in a limited installation space, improves the transmission and reception performance of the antenna and reduces noise interference.
