【摘要】：提出了一種新型分形結(jié)構(gòu)的天線,該分形結(jié)構(gòu)由多個共用一條邊的矩形環(huán)嵌套構(gòu)成。由于結(jié)構(gòu)的自相似特性,使天線能夠在多個頻段工作。研究表明,天線的通頻帶個數(shù)由分形結(jié)構(gòu)的矩形環(huán)個數(shù)控制,且各諧振頻點與相應(yīng)輻射單元的尺寸密切相關(guān)。設(shè)計了能同時工作在藍(lán)牙、WLAN和Wi MAX頻段的三頻天線,天線仿真的諧振頻點分別為2.44 GHz、3.55 GHz和5.59 GHz,相應(yīng)的帶寬分別為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)。實物的測試結(jié)果與仿真結(jié)果基本吻合,符合設(shè)計要求。
[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.
