摘要

许多医疗和工业应用需要在辐射天线的近场聚焦微波辐射。天线阵列在这种应用中是合适的和灵活的。近年来,分形天线和阵列因其优于传统天线而备受关注。论证了分形原理应用于聚焦阵列的可行性。研究了元素按二叉树分形进行空间分布的分形阵列的性质,并与传统阵列进行了比较。计算机仿真结果表明,聚焦分形阵列在具有良好聚焦性能的同时,具有相似的聚焦性能。

Investigation of the focusing properties of some fractal arrays
Many medical and industrial applications require focusing of microwave radiation in the near field of the radiating antenna. Antenna arrays are suitable and flexibel in such applications. Fractal antennas and arrays are finding much interest in recent years for the benefits they offer over conventional ones. The feasibility of deploying the fractal principle to focused arrays is demonstrated. The properties of fractal array whose elements are spatially distributed according to the binary tree fractal are investigated and compared with those of conventional array. Computer simulations results show that focused fractal array can have similar focusing properties while having favorable ones.
