Abstract

The invention provides a low-frequency magneto-electric composite mechanical antenna with a novel structure and a manufacturing method thereof, and belongs to the technical field of low-frequency communication. A structural unit of the low-frequency magneto-electric composite mechanical antenna comprises a core rod with a piezoelectric function, a core shell module with a piezomagnetic function and a hoop buckle for fastening and fitting the core rod and a core shell. The core shell is composed of a plurality of arc shell bodies, the inner diameters of the arc shell bodies are equal to the outer diameter of the core rod, the number of the arc shell bodies is at least two, and a telescopic gap is reserved between every two adjacent arc shell bodies. Compared with a traditional magneto-electric composite mechanical antenna, the low-frequency magneto-electric composite mechanical antenna of the novel structure has the advantages that the possible negative effect of strain conduction between different phases caused by chemical interface bonding is weakened, and strain conduction is timely, efficient and uniform.

Description

technical field [0001] The invention belongs to the technical field of low-frequency communication, and in particular relates to a low-frequency magnetoelectric composite mechanical antenna with a new structure. Background technique [0002] The miniaturization of ultra-long-distance underwater (underground) communication with low-frequency electromagnetic waves is a current research hotspot. The difference between the mechanical antenna and the traditional electric excitation antenna is that the former converts the information loading into electromagnetic energy through the form of mechanical motion to realize information transmission. This way of information transmission is not limited by the size of the current oscillation space of the traditional electric excitation antenna, and no longer needs impedance to match the circuit, which provides the possibility to realize efficient and miniaturized low-frequency communication. [0003] According to different implementation s...
