微带天线相对体积较小、剖面低、重量轻、结构设计灵活、制造简单,已被广泛应用于无线通信、遥感、导航、雷达等系统中。随着无线通信技术的发展,小型化、多频带微带贴片天线在无线通信中得到了广泛应用。本文设计了一种六边形三频带微带天线,采用同轴线馈电,在六边形贴片的每个顶点内侧进行120度的开槽,通过调整贴片开槽的几何形状和尺寸可以有效地获得三种不同的谐振模式,可应用于 L波段和C波段。用仿真软件CST对天线进行仿真分析,在工作频段满足S11<-10 dB。该天线具有结构简单、体积小、增益良好的特点,可以适用通信WiFi频段。
Microstrip antennas are relatively small in size, low profile, light in weight, flexible in structure design and simple in manufacture, and have been widely used in wireless communication, remote sensing, navigation, radar and other systems. With the development of wireless communication technology, miniaturized, multi-band microstrip patch antenna has been widely used in wireless communication. A hexagonal tri-band microstrip antenna is designed in this paper, a 120 degree notch is made inside each vertex of the hexagonal patch, which can be effectively used for L-band and C-band applications by adjusting the geometry and size of slotting of the patch to obtain three different resonant modes. Simulation software CST is used to simulate and analyze the antenna, and it satisfies S11<-10dB in the operating band. The antenna has the characteristics of simple structure, small size and good gain, which can be applied in the communication system and WiFi band.
