Abstract

The invention discloses a novel plasma antenna and a usage method thereof. The novel plasma antenna comprises a discharging room, a gas cylinder, a radio-frequency power supply, a glass tube and an alternating-current power supply. Plasma is caused in the discharging room; the plasma enters the glass tube to work to form a plasma antenna and thus realize signal receiving and transmitting. A plasma generation zone and a plasma working zone are separated and work independently, so that the density of the plasma in the plasma working zone can be adjusted and thus the working frequency range of the plasma antenna can be increased.

Description

technical field [0001] The invention relates to the field of plasma antennas, in particular to a plasma antenna with adjustable plasma density. Background technique [0002] Plasma antenna is an antenna that uses ionized gas as the electromagnetic energy conduction medium. Compared with the traditional antenna that uses metal conductors as the conduction medium, plasma is used as the medium of electromagnetic radiation, and plasma exists as the fourth state of matter, including Ions, electrons, and molecules are electrically neutral as a whole, and have the advantage of flexible design. Their length can be changed with the excitation power. The bandwidth, impedance, directivity, and radiation direction of the plasma antenna can vary with the frequency of the plasma and Due to its high frequency, when it is working, the electromagnetic waves emitted by the enemy radar are absorbed on the one hand, reflected on the other hand and deviate from the original direction, and the an...
