摘要
在研究传统Sierpinski毯式微带天线基础上,得到该天线的简化形式,进一步将其简化成准Sierpinski毯式微带天线,并提出了一种在贴片表面加载十字分形缝隙的新型结构。通过讨论十字缝隙的长度,宽度等参数对天线谐振频率,回波损耗的影响,找到了合适的参数值,在保证天线方向性变化不大的情况下,有效降低了天线的谐振频率,达到了缩减天线尺寸的目的。
Based on the contracted Sierpinski carpet fractal micro-strip antenna, a novel antenna structure with cross fractal slots on the surfaces of original patches is designed and studied. The effect of width and length of slots on the return loss and resonance frequency of antenna is discussed, and the appropriate results of the slots＇ width and length are obtained. Under the condition of directivity unchanged as the same level as original micro-strip antenna, this new type of antenna can reduce effectively the resonance frequency, and achieves the aim of size reduction.
