Abstract

The invention provides a flexible mechanical antenna communication system based on an electret and belongs to the field of low-frequency communication. The system is based on a rotary electret mechanical antenna method, a polymerization electret material is adopted as a carrier for charge storage of a transmitting antenna part, a flexible material is adopted as a supporting structure, the flexiblematerial is matched with a driving motor in a detachable mode, and the transmitting antenna part is light in overall mass, small in size, detachable, bendable, foldable, easy to carry, and the systemsuitable for being used in complex environments such as high maneuverability and small space.

Description

technical field [0001] The invention relates to the technical field of low-frequency communication, in particular to a design of an electret-based flexible mechanical antenna communication system. Background technique [0002] In view of the shortcomings of the current traditional low-frequency communication antennas, such as excessive size and exposure of targets in wartime, on January 6, 2017, DARPA proposed an idea of ​​a special / ultra-low frequency wireless transmitter based on a new mechanism——AMEBA (A Mechanically Based Antenna) project , the purpose is to change the way of generating low-frequency electromagnetic waves in principle, and propose a new mechanism, and initially give three principle schemes, namely rotating electric dipole, rotating electric monopole and rotating magnetic dipole. [0003] At present, a large number of researchers have carried out relevant research on this project. The realization of low-frequency electromagnetic waves is mainly concentrat...
