AI Technical Summary

Technical Problem

Existing flexible FPC antennas suffer from poor radiation performance and severe signal interference due to their close proximity to the metal base, making it difficult to meet the wireless network connection needs of multifunctional and miniaturized devices.

Method used

Design an LTE and WiFi dual-mode antenna. The antenna plate is fixed above the satellite message and positioning antenna by multiple support components, increasing the distance between the antenna plate and the base. A loop antenna design and a rectangular open area structure are adopted to reduce the impact of the base on the antenna plate and optimize the radiation performance.

Benefits of technology

It effectively improves the radiation performance of LTE and WiFi antennas, reduces interference with existing satellite messages and positioning antennas, meets the coverage requirements of the entire LTE and WiFi frequency bands, and improves the radiation performance and signal quality of the antennas.
