I. Nature of the course

"Microwave Technology and Antenna" is a basic course and an important elective course for undergraduates majoring in communication and electronic information. The teachers of the course team keep up with the latest development of electronic information technology, communication technology, computer technology and other fields, and constantly reform in the revision of textbooks, teaching content, methods and means, providing rich sharing resources and learning flexibility for learning objects, making the teaching of this course with a unique teaching mode.


2. Objectives and tasks of the course

The goal and task of this course is to enable students to master the "field" and "path" analysis methods and basic theories of microwave circuits, and have a systematic and full understanding of microwave passive circuits (from transmission lines to the composition and mechanism of various microwave passive components), the composition of microwave systems, and the working principle and design idea of antenna radiation receiving electromagnetic waves. The knowledge structure is reasonable and perfect, and it lays a good foundation for the subsequent study of microwave electronic circuit, electromagnetic compatibility principle and technology, radar principle and other courses, and the engineering design of microwave communication system, antenna theory research and engineering design in the future. Help students understand Microwave technology and antenna design application software (Microwave office,HFSS), and cultivate students' ability to learn new knowledge, master new methods, new skills, and solve complex engineering problems.


3. Connection and division of labor between this course and other courses

The prerequisite courses of this course are: advanced mathematics, general physics, circuit analysis, engineering mathematics, electromagnetic field and electromagnetic wave. The following courses include microwave electronic circuit, electromagnetic compatibility principle and technology, electromagnetic field numerical analysis, radar principle, communication principle and so on.


4. Teaching materials and reference books

In order to meet the needs of teaching reform and the development of science and technology, we compiled the teaching material of Microwave Technology and Antenna for this course, which was published by Electronic Industry Publishing House in 2003 and revised and published the 2nd edition in 2006. The 2nd edition was selected as the "11th Five-Year National Planning Textbook for General Higher Education"; In 2011, revised and published the 3rd edition and the supporting study guide, the 3rd edition of the textbook and the complete set of the study guide were selected as "National teaching materials for General Higher Education 'Twelfth Five-Year Plan'", in 2013, they were selected as "Twelfth Five-Year Plan" teaching materials of the Ministry of Industry and Information Technology, and won the second prize of Excellent teaching materials for ordinary colleges and universities in Shaanxi Province in 2015; In 2016, it continued to revise and publish the 4th edition, and in June 2021, the textbook was revised again and the 4th edition was published.
