Abstract

The invention belongs to the solid-state plasma and microstrip antenna technology, and more particularly, to a frequency reconfigurable coupled feed loop antenna, comprising: a semiconductor substrate, a dielectic plate, SPiN diode rings, a DC bias line, and a coupling feed source. When a metal contact area is connected to the positive electrode and the negative electrode of the DC bias line respectively, through the exerted DC current and voltage, all SPiN diode rings in the entire SPiN diode string can be put into a forward communication state. When the SPiN diodes are used to excite the solid-state plasma in forward-bias manner, the diodes can be applied for the electromagnetic radiation of the antenna. When the SPiN diodes are closed without bias, they take on a semiconductor dielectric state which can solve the mutually coupling problem between antennas so as to facilitate the design of a reconfigurable antenna. The frequency reconfigurable coupled feed loop antenna of the invention is small in size, reconfigurable, easy to be integrated, and has a simple structure. With the antenna, feeding becomes easy; and frequency can be jumped rapidly.

Description

technical field [0001] The invention belongs to the technical field of solid-state plasma and microstrip antenna, and in particular relates to a frequency reconfigurable coupling feeding loop antenna. Background technique [0002] With the further development of science and technology, wireless communication technology is playing an increasingly important role in people's lives. The development trend of the new-generation wireless communication system includes realizing high-speed data transmission, realizing the interconnection between multiple wireless systems, realizing the effective use of limited spectrum resources, and obtaining the ability to adapt to the surrounding environment, etc. Therefore, the requirements for antennas in the communication field are getting higher and higher. [0003] The antennas that have been researched so far are basically made of metal, so the shape of this antenna cannot be changed after it is manufactured, and it has a large radar scatte...
