介质陶瓷谐振器天线的研究进展

摘要

Dielectric ceramic resonator antennas (DRAs) have been widely used in satellite communication, base station and mobile communication systems. This paper summarizes the excitation, miniaturization, bandwidth enhancement techniques and frequency tuning in recent years. The relevant principles were given in theory. Finally, the trends for DRAs were proposed.%介质陶瓷谐振器天线广泛用于卫星通信、基站和移动通信系统中，本文综述介质陶瓷谐振器天线的馈电结构、小型化、带宽展宽技术和频率可调方法的最近研究成果，并从理论上解释其相关的工作原理，最后提出了介质陶瓷谐振器天线的发展趋势。
