摘  要： 本文設(shè)計(jì)了不同類型的分形天線的方法，并相應(yīng)地作出了對(duì)比，利用分形的特性來改善天線的輻射特性。在此基礎(chǔ)上嵌入了左手材料，并用計(jì)算機(jī)仿真軟件HFSS模擬了各項(xiàng)參數(shù)，與普通天線對(duì)比，分形貼片與左手材料對(duì)天線性能的影響。通過對(duì)比，我們發(fā)現(xiàn)所設(shè)計(jì)的分形天線能有效地減小天線地物理面積，回波損耗、駐波比等參數(shù)，左手材料可以有效提高增益，從而改善天線的性能。

Study on Fractal Antenna Based on LHMs

Abstract： Fractal antenna design method for different types and accordingly made a comparison, using fractal features to improve the radiation characteristics of the antenna. Based on this LHMs are embedded in, and we can use computer simulation software HFSS to simulate the various parameters, compared with an ordinary antenna, the impact of fractal patch antenna with left-handed material properties. By contrast, we find fractal antenna design can effectively reduce the antenna to the physical area, S11, VSWR and other parameters, left-handed material can effectively increase the gain, thereby improving the performance of the antenna.

Keywords:  fractal, LHMs, VSWR, gain
