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%。

Abstract:

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 slotting 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 described based on the numerical analysis.Simulation shows that the design can realize antenna with a 36% greater bandwidth and 34.2% smaller size.

Key words: micro-strip antenna;miniaturization;broadband
