Electromagnetic Field and Electromagnetic Wave Extracurricular Experiments Based on Amateur Radio Direction Finding
In the course of Electromagnetic Field and Electromagnetic Wave,there are many formulas and abstract concepts,which make it difficult to learn.Meanwhile,the amateur radio direction finding(ARDF)requires the use of transmitters,receivers,and requires the application of electromagnetic wave propagation,vector superposition and other related knowledge.Using ARDF as a carrier,an extracurricular experiment is developed to draw the antenna pattern of radio direction-finding receiver,and the abstract electromagnetic wave theory becomes intuitive.Students can understand the antenna pattern,antenna turntable,test method and other related theories in practice,which can greatly enhance students'interest in learning and improve the teaching quality of Electromagnetic Field and Electromagnetic Wave course.
