英文摘要： Terahertz technique is a frontfort cross-disciplinary, whose space and short-range communication system can provide over hundreds to thousands times of data rate of modern communication systems. It has attracted much interest from worldwide researchers. The electrical-large terahertz planar integrated array antenna is one of key components for transmitting terahertz waves in space with high efficiency, which can improve the transmission efficiency and integrity of terahertz communication system, and significantly reduce the system cost. However, only few literature from worldwide researchers discussed the electrical-large terahertz planar integrated array antenna for the high efficiency space transmission of terahertz waves. Hence, it has great significance to study the theory and application of the electrical-large terahertz planar integrated antennas. This proposal will investigate the electrical-large terahertz planar integrated array antenna. The design and realization of high gain and high radiation efficiency terahertz planar integrated array antenna will be proposed; and terahertz planar integrated array antennas with stable radiation beam direction will be studied. Multiple-beam terahertz planar integrated array antenna will be designed based on the study of low loss feeding system; and novel design methods for planar integrated orbital angular monument antenna will be proposed for the realization of terahertz planar integrated antennas with single and multiple orbital angular monument modes. The measurement method for terahertz planar integrated antennas will be investigated and a measurement system will be set up to measure and verify the designed terahertz planar integrated array antennas.
