摘　　要：以微带天线技术为基础,以工作于ISM频段微带贴片天线为例,采用Ansoft公司的电磁仿真软件HFSS,对不同介电常数、不同介质板厚度、矩形贴片开槽开缝、加载寄生贴片等微带贴片天线进行了仿真。通过数值分析,阐述了介电常数、基板厚度、贴片开槽、寄生贴片等因素对微带贴片天线尺寸和频带宽度的影响。仿真结果表明,设计能够实现两种性能的天线结果,天线的宽度达到36%。天线的尺寸缩小了34.2%。Based on the micro-strip antenna technologies and with the antenna working at ISM frequency as an example, the paper simulates the micro-strip antenna in different permittivity and different thickness plate, in slot- ting patch, and in loading parasitic patch using the simulation tool HFSS from ANSOFT. The effects of the dielectric constant, plate thickness, patch slot and parasitic patch on micro-strip patch antenna size and bandwidth is de- scribed based on the numerical analysis. Simulation shows that the design can realize antenna with a 36% greater bandwidth and 34.2% smaller size.
