可编程重构的固态等离子体芯片天线阵基础研究

This project is the first to put forward the concept of the reconfigurable chip antenna array based on solid state plasma. Based on the semi classical quantum theory, the carrier distribution the characteristics, the semimetal electromagnetic characteristics and the volt-ampere characteristics of the solid plasma are studied. The basic electromagnetic characteristics of solid state plasma are obtained. Through numerical modeling, simulation and parameter optimization of solid state plasma chip antenna array, the key technologies of solid state plasma programmable reconfigurable chip antenna array such as electric control technology, beam control technology, chip manufacturing processes and technology are studied. Based on GaAs process, the principle prototype of two states reconfigurable (radiation pattern) solid plasma chip antenna array will be designed and fabricated on the base of above-mentioned research. Through the simulation optimization, fabrication and testing of the principle prototype, the radiation characteristics and the reconfigurable feature of the two state reconfigurable solid state plasma GaAs chip antenna array are verified. The solid state plasma programmable reconfigurable chip antenna can be integrated with the RF front end of the system to realize the miniaturization and integration of the whole system, and realize the system on chip in the true sense. There are many other excellent advantages in this antenna, such as intelligent cancellation anti-jamming, good stealth performance, inexpensive and suitable to the short wavelength condition such as millimeter wave. This antenna is likely to bring revolutionary change for the future radar and wireless communication system.
