摘要

本文用等效电路的概念对w槽加载单、双层介质微带天线进行了分析。天线显示双共振。单层贴片的谐振频率分别为2.91 GHz和3.88 GHz，双层贴片的谐振频率分别为4.17GHz和5.78GHz。发现单层贴片天线的频率比为1.33，双层介电贴片天线的频率比为1.38。通常发现频率比取决于槽长、槽宽和槽角。单层贴片天线在上下谐振频率下的带宽分别为1.71%和1.68%，而在两层介质下的带宽分别增加5.28%和2.77%。将理论结果与IE3D仿真结果进行了比较，两者吻合较好。

W-slot loaded patch antenna for dual-band operation

In the present paper W-slot loaded single and two layer dielectric microstrip patchantenna has been analysed using equivalent circuit concept. The antenna shows dual resonance. The resonance frequency of single layer patch is found to be 2.91 GHz and 3.88 GHz which increases for two layer dielectric antenna 4.17GHz and 5.78GHz. The frequency ratio is found to be 1.33 for single layer patch antenna and 1.38 for two layer dielectric patch antenna. In general the frequency ratio is found to depend on slot length, slot width and slot angle. The band width of single layer patch antenna is found to be 1.71% and 1.68 % for lower and upper resonance frequency while it increases for two layer dielectric 5.28 % and 2.77 %. The theoretical results are compared with the simulated results obtained from IE3D and they are in close agreement.
