Chinese Abstract:
In the future, the communication system will work at a higher frequency and provide a higher transmission rate. Frequency enhancement will make it difficult to provide wide beam coverage, so flexible beam tracking will become an inevitable trend of technology development. The terahertz beam tracing antenna array reported in this paper can provide a good solution for flexible and agile beam tracking. The antenna array receives 40 GHz pilot signal and the signal transmitted by backtracking beam is 120 GHz. The simulation results show that the antenna array with sandwich stack structure can realize the function of incident wave tracing successfully. The radiation pattern of the antenna shows that the backtracking beam of the antenna array is at 19.9 ° with a gain of 23.87 dB and a relative error of only 0.5% in the backtracking direction under the condition of 20 ° incident wave. This means that at a transmission distance of 5 km, the horizontal error is only 8.7 M.

Introduction:
Hu Weidong, admitted to the Department of electronic engineering of Beijing University of technology in 1993, stayed in school after graduation in 2004, visiting scholar of national millimeter wave Key Laboratory of City University of Hong Kong in 2010, now doctoral supervisor of Beijing Key Laboratory of millimeter wave and terahertz technology of Beijing University of technology, external Professor of terahertz Key Laboratory of Ministry of education of Capital Normal University, main research field is millimeter Wave / terahertz space exploration, remote sensing and communication technology. He participated in the major scientific instrument project of NSFC (61527805), presided over the major project of terahertz imaging for civil aerospace during the 12th Five Year Plan, and now has 3 achievements passed the ministerial appraisal, filling the domestic gap. In 2011, it won the national defense science and technology progress award, ranking first; in 2012, it developed the first domestic 220 GHz terahertz radar, and obtained good experimental results. In 2016, it took the lead in the research of long-range detection of terahertz radar in Dunhuang and Xinjiang. In terms of academic part-time jobs, he served as vice chairman of the international conasense Association in China, chairman of the Organizing Committee of the China EU meteorological radar academic forum, member of the radio frequency planning expert group of the Ministry of industry and information technology, member of the antenna and radio frequency technology special committee, served as the session chair of the International Conference for many times, as the reviewer of IEEE Transactions on antenna and propagation and electronic journal.
