摘要
对带有地板的普通三元八木天线的振子进行了Koch分形处理,并对其进行了测试.测试结果表明,若两天线具有相同的高度,分形八木天线具有多频特性,同时工作频率降低为普通八木天线的77%,辐射特性和普通八木天线相差不大.如果两种天线的工作频率相同,则分形八木天线的高度和普通八木天线相比可以压缩23%.
A new-style fractal Yagi -Uda Antenna is designed and tested by means of doing Koch fractal to traditional ternary Antenna with floor. The result shows that if the two kinds of antennas are of the same height, the fractal Yagi-Uda Antenna has multi-frequency property and its operating frequency decreases to 77% of that of the traditional Yagi-Uda Antenna, but the radiation characteristic of the fractal Yagi-Uda Antenna hardly changes from the traditional one. If the two kinds of antennas work at the same operating frequency, the height of fractal YagiUda Antenna can be 23% lower than that of the traditional Yagi-Uda Antenna.
