The radiation pattern is an important parameter of the antenna performance. This parameter needs to be measured not only accurately but also as fast as possible. For this purpose, the automatic measurement system has been developed. In this research, the system is implemented to analyze the radiation characteristic of a Yagi antenna by measuring its radiation pattern. The measurement result of the patterns is compared to those of the table characteristics of the Yagi antenna as well as a computer simulation. For this purpose, a Yagi antenna is designed and realized as the radiation pattern measurement object. Then, the students experiment to measure and analyze the effect of parasitic elements on the radiation pattern performance of the antenna. The questionnaire is carried out as the method of the research and directed to the students of the Telecommunication Study Program, Bandung State Polytechnic, to get the perception of the object performance.
