摘要
设计一种工作于X/Ku双频段的背腔式微带贴片天线。它采用背腔式口径耦合馈电扩展单层微带贴片的工作带宽,通过在微带贴片上加载"王"字形缝隙使其可以工作于X和Ku两个波段。基于HFSS的电磁仿真结果表明,设计的微带天线在X和Ku两个波段均有优良的辐射性能。
An X/Ku dual-band microstrip antenna is introduced in this paper.A cavity-backed microstrip patch antenna with a single layer is designed to obtain good wideband performance.The microstrip patch is loaded by a slit with Chinese wang-shape to operate at both X and Ku bands.The simulation results of HFSS software show that the radiation performances of presented antenna at X and Ku bands are good and the antenna can meet the requirements of engineering.
