通信中的薄型天线是一种新方法。分形几何是一种实现尺寸减小的方法。提出了一种利用多天线技术的自相似分形天线并进行了实验研究。所提出的天线采用了空间填充康托和分形几何的自相似特性，以缩小天线的尺寸。该天线设计为在 MICS 频段（医疗植入通信服务）下运行，用于无线远程医疗应用。原型天线表现出宽带特性并提供了良好的回波损耗一致性 (S11)。将实验回波损耗与使用矩量法获得的回波损耗进行了比较。在天线中使用自相似概念的目的是使其在控制谐振和带宽方面具有灵活性。在本文中，通过在所有迭代 (n) 中保持回波损耗 (S11) 大约超过 –30 dB 来检验分形几何的自相似性，原型天线的回波损耗大于 –10 dB，并表现出宽带特性。
Low profile antenna in communication is a new methodology. Fractal geometry is a methodology through which size reduction is achieved. A Self-similar fractal antenna using multicantor technique is proposed and experimentally studied. Space-filling cantors and self-similarity properties of fractal geometry have been adopted in the proposed antenna to miniaturize the size of antenna. The antenna is designed in such a way to operate at MICS band (Medical Implant communication Service) for wireless telemedicine application. The prototype antenna exhibits wideband characteristics and provides a good agreement of return loss (S11). Experimental return loss has been compared with that which is obtained using method of moments. The objective of using self-similar concept in antenna makes it flexible in terms of controlling the resonance and bandwidth. In this paper, the Self-similar property of fractal geometry is examined by maintaining return loss (S11) more than –30 dB approximately in all the iterations (n) and the prototype antenna has return loss greater than –10 dB and exhibits wideband characteristics.
