Dual drive very low frequency mechanical antenna system and communication control method thereof

Abstract

This invention belongs to the field of wireless communication technology, specifically disclosing a dual-drive very low frequency (VLF) mechanical antenna system and its communication control method. The system includes an environmental sensing unit, a data processing and control unit, a dual-drive mechanical antenna, and a feedback monitoring unit. The transmitting unit in the dual-drive mechanical antenna adopts a composite structure combining a piezoelectric layer and a magnetostrictive layer. Through piezoelectric and electromagnetic driving methods, it works collaboratively under conditions of synchronized signal frequency and maintaining a specific phase difference, jointly exciting the vibration of the magnetostrictive layer, thereby improving the mechanical vibration amplitude and radiation efficiency. The environmental sensing unit acquires environmental parameters such as seawater salinity, water depth, and temperature in real time; the feedback monitoring unit monitors the antenna's radiated magnetic field and vibration state, and feeds the data back to the control module, forming a closed-loop adaptive control. This invention effectively improves the radiation intensity and energy efficiency of VLF communication signals, realizing stable and efficient cross-medium wireless communication in complex marine environments.
