Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0013] Such as figure 1 The schematic diagram of the structure of the magnetoelectric mechanical resonant antenna integrated with the permanent magnet is shown. The magnetoelectric mechanical resonant antenna 1 includes a permanent magnet 101, a magnetostrictive material 102, a piezoelectric material 103 and a wire 104. The two sides of the piezoelectric material 103 are symmetrically bonded to each other. For the same magnetostrictive material 102 , the permanent magnet 101 is placed on or around the side of the magnetostrictive material 102 away from the piezoelectric material 103 ....

Abstract

The invention relates to a magnetoelectric mechanical resonant antenna integrated with a permanent magnet, which adopts a magnetostrictive material-piezoelectric material-magnetostrictive material three-layer composite structure, so that the antenna detects, receives and transmits electromagnetic waves through mechanical resonance, and the size and the structure of the antenna are greatly reduced compared with those of a traditional antenna. Meanwhile, by arranging the permanent magnet, the magnetoelectric effect is improved, the detection and transmitting capability of the antenna is improved, and the antenna has the advantages of being small in size, simple in structure and low in manufacturing cost; the antenna can replace a traditional antenna or be matched with the traditional antenna, and is high in universality.

Description

technical field [0001] The invention relates to a signal transmission technology, in particular to a magnetoelectric mechanical resonant antenna integrating permanent magnets. Background technique [0002] The traditional antenna is directly driven by the power supply, forming an oscillating electric field in the antenna to radiate electromagnetic waves into space. In order to efficiently radiate electromagnetic waves, the size of the antenna needs to be on the same order of magnitude as the wavelength of the radiated electromagnetic waves. Since the wavelength of low-frequency electromagnetic waves is as long as several kilometers or tens of kilometers, the size of traditional low-frequency antennas is also very large, making them unable to be used in mobile electronic devices. Contents of the invention [0003] Aiming at the problems of large volume and complicated structure of existing antennas, a magnetoelectric mechanical resonant antenna integrated with permanent mag...
