【摘要】：提出了一种新型分形结构的天线,该分形结构由多个共用一条边的矩形环嵌套构成。由于结构的自相似特性,使天线能够在多个频段工作。研究表明,天线的通频带个数由分形结构的矩形环个数控制,且各谐振频点与相应辐射单元的尺寸密切相关。设计了能同时工作在蓝牙、WLAN和Wi MAX频段的三频天线,天线仿真的谐振频点分别为2.44 GHz、3.55 GHz和5.59 GHz,相应的带宽分别为7.0%(2.35 GHz~2.52 GHz)、15.0%(3.28 GHz~3.81 GHz)和30.1%(5.13 GHz~6.95 GHz)。实物的测试结果与仿真结果基本吻合,符合设计要求。
[Abstract]:A new type of antenna with fractal structure is proposed. The fractal structure is composed of several rectangular rings with one edge in common. Because of the self-similarity of the structure, the antenna can work in multiple frequency bands. The results show that the number of frequency bands of antennas is controlled by the number of rectangular rings with fractal structure, and the resonant frequency points are closely related to the size of the corresponding radiating units. A three-frequency antenna which can operate simultaneously in Bluetooth WLAN and Wi MAX band is designed. The resonant frequency points of antenna simulation are 2.44 GHz 3.55 GHz and 5.59 GHz, respectively. The corresponding bandwidth is 7.0% (2.35 GHz~2.52 GHz), 15.0% (3.28 GHz~3.81 GHz) and 30.1% (5.13 GHz~6.95 GHz).), respectively. The test results are in good agreement with the simulation results and meet the design requirements.
