Analysis of Transmission Characteristics on FSK-based Rotating-magnet Based Mechanical Antenna

Rotating-magnet based mechanical antenna (RMBMA) is a new low frequency electromagnetic transmitting technology, of which the electromagnetic waves are excited by rotating-magnet directly. On the basis of the system analysis model of RMBMA, this paper reveals the case of FSK modulation and information loading strategy. Then, the transient response analytical method of transmission characteristics is proposed and the transmission capacity expression is derived. At last, the influencing factors of transmission characteristics are determined. Simulation results demonstrate the effectiveness and superiority of the proposed method.
