Abstract

The invention provides a modulation method and system of a magnetoelectric mechanical antenna, a computer device and a readable storage medium thereof. The modulation method of the magnetoelectric mechanical antenna comprises the step of applying a bias magnetic field to the heterojunction antenna to be modulated; detecting the ferromagnetic resonance frequency of the heterojunction antenna to be modulated, and comparing the ferromagnetic resonance frequency with the mechanical resonance eigenfrequency of the heterojunction antenna; and if the ferromagnetic resonance frequency and the mechanical resonance eigenfrequency are not equal in an error range, adjusting the size of the bias magnetic field, so that the resonance eigenfrequency and the ferromagnetic resonance frequency are equal in the error range. By the adoption of the method, BFSK modulation communication of the mechanical antenna can be directly achieved, BFSK modulation achieved by changing the mechanical resonant frequency of a system through an additional circuit is avoided, and therefore the BFSK modulation scheme is simplified, and the integration of the mechanical antenna is facilitated.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to a modulation method, system, computer equipment and a readable storage medium of a magnetoelectric mechanical antenna. Background technique [0002] Traditional antennas rely on the resonance of electromagnetic waves, and their size needs to be comparable to the wavelength of electromagnetic waves to achieve resonance, so their size is limited by the wavelength. A class of magneto-electromechanical antennas that rely on mechanical resonance helps reduce the size of conventional antennas. Mechanical antennas are often modulated using BFSK (Binary Frequency Keying) for data transmission. [0003] At present, the same mechanical antenna realizes the transmission of two resonant frequencies. The BFSK modulation scheme adopted is to change the resonant frequency by connecting a bypass structure circuit in series or parallel to the antenna structure, so that the same mechan...
