Course Nature: "Radio Frequency Circuits and Antennas" is an important professional basic course for information engineering, electronic science and technology, integrated circuits and physical electronics. It is closely related to the modern electronic information industry, especially the wireless communications and mobile communications industries. However, these courses are classic traditional courses. How to enable undergraduates who do not have a strong foundation in mathematics and physics to learn these courses well and understand and master the knowledge and technologies most closely related to modern electronic information technology within a limited number of hours is an important task. A difficult problem facing these courses is a constrained optimization problem.
