Under traditional teaching models, students often struggle to establish concrete connections between mathematical derivations and engineering applications. To address this issue, this paper proposes utilizing a self-tracking antenna system, a typical engineering system, as a consistent engineering teaching example throughout the course. It integrates the core theoretical knowledge of “signals and systems” into the analysis, modeling, and simulation practices of this example. By reconstructing a theory-case-practice integrated curriculum, designing blended learning-based teaching activities, and deeply excavating and integrating ideological and political elements, a new teaching model centered on cultivating engineering application capabilities and shaping values has been constructed. Teaching practice indicates that this reform significantly enhances students’ learning interests, engineering practical abilities, and comprehensive qualities in solving complex engineering problems, providing a valuable reference for cultivating high-quality talents adapted to modern communication technology development.Curriculum ideology and politics,Engineering case studies,Self-tracking antenna,Signals and systems
