摘要
为了实现一款天线在ISM2.4G(2.4~2.4835GHz)、Bluetooth、GPS、WLAN(2.4~2.48GHz)等多频段同时工作,设计了基于分形理论的类Minkowski分形微带天线,方案中对原有的Minkowski分形结构和接地板进行改进。通过仿真分析与优化设计使得天线尺寸缩减至90mm×71mm×1.6mm,谐振频率为2GHz,工作在0.93GHz^3.02GHz频段,相对带宽为105.82%,最大增益可达1.89dB。最终天线能够进行良好的阻抗匹配,对天线带宽进行展宽,达到了超宽频带天线的要求。
In order to achieve that an antenna works in ISM2.4G(2.4~2.483 5 GHz), Bluetooth,GPS,WLAN(2.4~2.48 GHz) and other multi-frequency band at the same time,the Minkowski fractal microstrip antenna based on the fractal theory is designed, and the original Minkowski fractal structure and ground plate are improved. Through simulation analysis and optimization design, the antenna size is reduced to 90 mm×71 mm×1.6 mm, the resonance frequency is 2 GHz, working in the frequency band of 0.93 GHz^3.02 GHz, the relative bandwidth is 105.82%, and the maximum gain can reach 1.89 dB. Finally, the antenna can carry out good impedance matching, and the bandwidth of the antenna is broadened to meet the requirements of the UWB antenna.
