Plasma flexible antenna system

Abstract

The invention provides a plasma flexible antenna system comprising a radio frequency surface wave plasma excitation system, an antenna body, a feed system and a control component. The radio frequency surface wave plasma excitation system excites the antenna body by adopting an inductive coupling excitation mode. An excitation power supply outputs adjustable excitation signals to generate and maintain surface wave plasma. The shape of the antenna body can be adjusted so as to change the feature parameters of the antenna and realize rapid reconstruction. The feed system feeds communication signals in the flexible antenna by adopting a capacitive coupling signal feed mode. A control system can adjust the shape of the flexible antenna. The strength of the antenna system can be enhanced and flexibility of the antenna body can be increased so that the problem that the conventional plasma antenna is fragile can be solved and damage of the antenna can be prevented. Besides, the features of antenna impedance, directivity, polarization, bandwidth and gain can be realized by changing the shape of the antenna and the gas discharge state so as to extend the reconstructable range of the plasma antenna.

Description

technical field [0001] The invention relates to the technical field of gas discharge and wireless communication applications, in particular to a surface wave plasma flexible antenna system based on an inductive coupling excitation mode. Background technique [0002] On the basis of the reality that modern military warfare has higher and higher requirements for weapons and equipment, strike accuracy, attack range and survivability have become the main directions of weapon research. As far as the survivability of weapons is concerned, in order to improve the safety of weapons and equipment during combat, advanced stealth technology must be adopted. [0003] Stealth technology, as the most important and effective means of penetrating defense tactics, still needs continuous improvement to realize the powerful "vitality" of modern weapons and equipment. Among many stealth technology implementation methods, changing the shape of weapons and equipment or coating the surface with a...
