Abstract: In order to improve the comprehensive innovation experiment of RF microwave and antenna practical courses and project is out of actual engineering, design of microstrip antenna for unmanned aerial vehicle (UAV) obstacle-avoidance radar miscrostrip antenna is taken as an experiment project of RF microwave and antenna practice course. Students complete the process of independent design, simulation, optimization, production and testing of the antenna. Not only it can help students increase their learning interest, broaden their horizons, improve their abilities of applying professional knowledge and solving practical problems independently, but also it can help students culture their innovation consciousness and innovation ability.
