Abstract:

Solid silicon-based plasma channel can be formed when the surface PIN diode is conducted. This kind of channel has metal property and can transmit electromagnetic waves. The channel can radiate electromagnetic signals when the channel unit are coupled to a specific structure. We briefly introduced the formation mechanism of the channel, designed and conducted the different cell of surface PIN diode array with professional software, and got monopole, dual band, Yagi-Uda antenna and other structures. We expect to do some research on the radiation performance of silicon-based plasma channel by using those different structures. The simulation results show that the silicon-based plasma channel can radiate electromagnetic waves, change the radiation frequency, regulate the multi-frequency band, and reconfigure the dynamic radiation pattern by using the dynamic regulation of surface PIN diode array. Therefore, silicon-based plasma array antenna has reconfigurable, intelligent, and cloaking properties, as well as many other advantages. These systematic theoretical studies can help people to get a further understanding of silicon-based solid plasma channel, and provide theoretical guidance for the design and manufacture of this kind of antenna.
