摘　　要： 在电波与天线课程中引入双极化相控阵天线设计用于驱动教学模式,以方案设计、电磁仿真和加工实验为手段,开展面向工程应用的实践教学改革探索,以达到有效提升教学效果的目标。阐述了双极化相控阵天线的特点和教学应用方法,以双极化介质谐振器天线的设计为例,进行了中心频率为5GHz的天线单元的电磁仿真和加工测试工作。研究结果表明,双极化介质谐振器天线是一种有效的双极化相控阵天线单元实现方案,对实际工程应用起到有益的参考作用,同时介质谐振器作为一种新型的天线,在教学方面具有创新性。 It is proposed that a project-driven teaching mode for the dual-polarized phased array antenna is introduced into the Radio Wave and Antenna course,and by means of the scheme design,the electromagnetic simulation and the machining experiment,the practical teaching reform on engineering application is carried out so as to achieve the goal of improving teaching effectiveness.The characteristics and teaching methods of the dual-polarized phased array antenna are described. By taking the design of the dual-polarized dielectric resonator antenna as an example,the electromagnetic simulation and the processing test of the antenna unit with center frequency of 5 GHz are carried out.The research results show that the dual polarized dielectric resonator antenna is a good scheme to realize the dual-polarized phased array antenna unit,providing some useful references for the real engineering application.At the same time,as a new type of the antenna,the dielectric resonator is innovative in the teaching.
