space-filling

The simulation and test results show that the space-filling feature of Hilbert fractal structure antenna can be effectively transformed into the size-reducing feature, and that the RFID tag antenna with one-dimension Hilbert fractal structure is of higher efficiency.

仿真和实测结果表明，Hilbert分形结构天线的空间填充特性可有效转化为标签天线的尺寸缩减特性，而且一维Hilbert标签天线具有更高的天线效率。

Fractal has unique space-filling capacity and self-similar properties. When it is used to design the antenna, fractal antenna can be gained. The fractal antenna can realize the miniaturation and multi-frequency characteristics of antenna.

分形独有的空间填充能力和自相似属性用于天线的设计时，就得到了分形天线，可以实现天线的尺寸减缩性和多频特性。

As antennas are passive elements, the electrical characteristics of them are decided by the structure mainly. Generally, fractal structure has two special properties: space-filling property and self similarity property which may help the antenna have good performance.

天线作为一种无源器件，电气性能主要是由自身的结构决定的，分形天线具有许多特殊的性质，最主要的是空间填充性和自相似性。
