Abstract

The invention provides a low-frequency magnetoelectric composite mechanical antenna with a novel structure and a manufacturing method thereof, belonging to the technical field of low-frequency communication. The structural unit of the main body of the low-frequency magnetoelectric composite mechanical antenna with a novel structure according to the present invention includes a mandrel with piezoelectric function, a core shell module with piezoelectric function, and a clip buckle for fastening and fitting the mandrel and the core shell. Wherein, the core shell is composed of a plurality of arc shells whose inner diameter is equal to the outer diameter of the mandrel. gap. Compared with the traditional magnetoelectric composite mechanical antenna, the low-frequency magnetoelectric composite mechanical antenna of the new structure of the present invention has the advantage of weakening the possible negative effects of strain conduction between different phases caused by chemical interface bonding, and the strain conduction is timely and Efficient and uniform.

Description

Technical field [0001] The present invention belongs to the field of low-frequency communication, and more particularly to a new type of low-frequency magnetoelectric composite mechanical antenna. Background technique [0002] Small-duty of communication under low frequency electromagnetic waves (ground) is current research hotspots. The mechanical antenna is different from the traditional electrical excitation antenna in that the former is to transform information to electromagnetic energy into electromagnetic energy through mechanical motion. This information is transmitted, is not limited in the size of the current oscillating spatial size of the traditional electric excitation antenna, no need to impedance to match the circuit, providing a possible low frequency communication to achieve efficient and miniaturization. [0003] According to different implementations, mechanical antennas can be roughly classified as three categories: electret, permanent magnet, piezoelectric res...
