摘要

本文提出了一种具有类闵可夫斯基边形结构的微带贴片天线。它由微带馈线馈电，并引入λ/4阻抗变换器提供平滑的过渡阻抗，以提高阻抗匹配。给出并详细分析了分形天线不同迭代的设计过程和性能。最后，为了演示目的，制作了二次迭代版本的类闵可夫斯基侧分形天线并进行了测试。测量结果与模拟结果吻合较好。测量结果表明，谐振频率为2.14GHz，回波损耗为-24dB。与相同谐振频率的方形贴片天线相比，本文提出的二次迭代分形天线的面积减小了43.7%。同时不降低天线的性能。

Compact Microstrip Antenna Based on Minkowski-Like Sided Fractal

In this paper, a compact microstrip patch antenna with Minkowski-like sided fractal structure is presented. It is fed by a microstrip feed line and a λ/4 impedance converter is introduced to provide smooth transitional impedance for improved impedance matching. The design process and performance of the fractal antennas with different iterations are given and analyzed in detail. Finally, for demonstration purpose, the second iteration version of the Minkowski-like sided fractal antenna is fabricated and tested. Measurements are in good agreement with the simulations. Measurements show that the resonant frequency is 2.14GHz with the return loss of -24dB. The proposed 2nd iteration fractal antenna provides an area reduction of 43.7% as compared with the square patch antenna with the same resonant frequency. Meanwhile, it does not degrade the performance of the antenna.
