Problems solved by technology

[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. Three basic schemes are given, namely rotating electric dipole, rotating electric monopole and rotating magnetic dipole

Embodiment Construction

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the specification of the present application. Obviously, the described embodiments are only for illustration, and are not intended to limit the present application.

[0016] A design idea of ​​a specific implementation of an electret-based low-frequency flexible mechanical antenna communication system is as follows: figure 1 As shown, the low-frequency antenna low-frequency flexible mechanical antenna communication system is composed of a power supply, a drive motor, a rotating support structure, an electret material, a photoelectric sensor module, a lock-in amplifier, and a fluxgate meter.

[0017] The power supply supplies power for the normal operation of the entire system;

[0018] The driving motor rotates together with the rotating support structure driven by a power source;

[0019] After the elec...

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...
