提出了一种适用于低频应用的小型化平台容差天线。提出了一种集总电容加载的裂环谐振器（SRR）天线，该天线结构紧凑、低剖面、易于加工。它的最大尺寸为<$/9，i10 dB带宽为1%。小型化人造磁导体表面（AMC）是使用电容加载金属贴片设计的，单个元件的测量值仅为<$=70。将SRR放置在AMC上方可将带宽提高到1.5%至3.5%之间，具体取决于AMC的总体尺寸，并产生测量为0.11、£0：17、£0：019“的平台容差天线。研究和讨论了天线在有通孔和无通孔的AMC上的性能。AMC安装天线的性能在自由空间和在接地平面进行了比较。
A miniature platform tolerant antenna is presented which is suitable for low frequency applications. A Split Ring Resonator (SRR) antenna loaded with lumped capacitances is proposed, and the antenna is compact, low proflle and easy to fabricate. It has a maximum dimension of ‚/9 and i10dB bandwidth of 1%. Miniaturized artiflcial magnetic conductor surfaces (AMCs) are designed using capacitance loaded metal patches with individual elements measuring just ‚=70. Placing the SRR above the AMC improves the bandwidth to between 1.5 and 3.5% dependent on the overall size of the AMC and produces a platform tolerant antenna measuring 0.11‚£0:17‚£0:019‚. The performance of the antenna over an AMC with and without vias is studied and discussed. The AMC mounted antenna performances in free space and over a ground plane are also compared.
