Description

technical field

[0001] The invention relates to an antenna used in the technical field of communication, in particular to a self-reconfigurable plasma antenna. Background technique

[0002] A traditional antenna is defined as a metal device for transmitting and receiving radio waves, or a metal conductor with a certain shape and structure. Therefore, the antenna design in the past has focused on the geometric structure, physical size, metal material selection, electrical coupling structure, multi-antenna design, and / or electromagnetic waveform characteristics of the antenna, such as the transmission wavelength, transmission efficiency, and transmission waveform of the antenna during operation. reflection and more. The size of an antenna is closely related to its radiation efficiency. In order to radiate energy as efficiently as possible, the length of the antenna is usually half or quarter wavelength. In this sense, once the size of an antenna using metal as a conductor i...
