Dynamic characteristics of the mechanical antenna based on vibrating permanent magnet
In the traditional field of wireless communication,the application of long-wave communication is constrained on small and medium-sized platforms due to the requirement of large sized signal-transmitting antennas.This paper proposes and develops a three-degree-of-freedom cut-out beam structure of the vibration permanent magnet type mechanical antenna prototype based on the inverse piezoelectric effect,vibration theory,and Maxwell's equations.It establishes an electric-mechanical-electromagnetic energy theory model and investigates the radiation influencing factors of the mechanical antenna along with its frequency modulation technique.The experimental results validate that electromagnetic wave signals can be frequency-modulated by exciting different vibration modes of the mechanical antenna prototype.This research offers novel theoretical and technical perspectives for low-band signal communication.
