摘要
本文利用星形六边形分形的概念，设计并仿真了一种独特的多波段微带贴片天线。这项工作的重要贡献是对现有的矩形缺口分形设计几何图形进行了逻辑修改。所提出设计的结构具有FR-4环氧基板，厚度为1.6 mm，介电常数为4.4，损耗正切为0.02。利用高频结构模拟器(HFSS)软件进行仿真，对天线参数进行了优化，使其工作在24.9 ~ 28.1 GHz的频率范围内，总带宽为3.2 GHz。设计的天线非常紧凑，尺寸仅为15 mm X 15 mm，在28 GHz时产生4.688 dB的峰值增益。该天线谐振频率为26/28 GHz，适用于在马来西亚推出的第五代(5G)移动通信毫米波(mmWave)频段和本地多点分布服务(LMDS)。
Multiband Fractal Antenna for 26/28 GHz Millimeter Wave Band
This article presents the design and simulation of a unique multiband microstrip patch antenna, using the star hexagon fractal concept. The significant contribution in this work is the logical modifications in the existing fractal design geometry with a rectangular notch. The configuration of the proposed design has a substrate of FR-4 epoxy having a thickness of 1.6 mm, a dielectric constant of 4.4, and a loss tangent of 0.02. Simulated using High-Frequency Structure Simulator (HFSS) software, the parameters of the proposed antenna were well optimized so it would be suitable to be operated in the frequency range from 24.9 GHz to 28.1 GHz with an overall bandwidth of 3.2 GHz. The designed antenna is remarkably compact, having the size of just 15 mm X 15 mm, which produces a peak gain of 4.688 dB at 28 GHz. Having resonant frequencies at 26/28 GHz, this antenna finds application in fifth-generation (5G) mobile communication millimeter wave (mmWave) band roll out in Malaysia and Local Multipoint Distribution Service (LMDS).
