寄生单元加载的高增益可重构对称扇形贴片天线

High gain reconfigurable symmetrical sector patch antenna loaded with parasitic elements

    摘要
  • 摘要:
    目的 为满足舰载通信系统对多功能天线的需求，提出了一种基于八木天线的新型高增益四波束可重构贴片天线。
    方法 它主要由4个对称的扇形单元组成，用于控制天线辐射方向图的4个PIN二极管分别加载在中心贴片和4个扇形贴片之间。通过切换PIN二极管的导通/截止状态，控制天线波束辐射方向，以实现4种不同的方向图。通过添加弧形寄生单元作为反射器和引向器，增加天线增益并抑制旁瓣。
    结果 实测结果表明，该天线可以在4种模式下分别实现方位角平面45°，135°，225°和315°共4个方向的波束指向。在5.47～6.05 GHz，所有模式均可实现7.46 dBi的高平均增益。
    结论 该天线具有高增益、低剖面、控制简单等优点，可以根据舰船通信需求，动态调整天线的辐射方向，减少信号干扰，提高通信质量。

     

    Abstract:
    Objectives To meet the demand for multifunctional antennas in shipborne communication systems, this paper proposes a novel high gain four-beam reconfigurable patch antenna based on Yagi antenna.
    Methods It is mainly composed of four symmetrical sector elements. The four PIN diodes used to control the radiation field pattern of the antenna are loaded between the central patch and the four sector components respectively. By switching the on/off state of the PIN diode, the antenna beam direction can be controlled to achieve four directional patterns. By adding arc-shaped parasitic units as reflectors or deflectors, the antenna gain is increased and the side lobe is suppressed.
    Results The experimental results show that the antenna can achieve four types of beam pointing with azimuth plane \varphi = 45^\circ , \varphi = 135^\circ , \varphi = 225^\circ , \varphi = 315^\circ in four modes. In the range of 5.47 to 6.05 GHz, a high average gain of 7.46 dBi can be achieved for all modes.
    Conclusions This antenna has the advantages of high gain, low profile, and simple control. It can dynamically adjust the radiation direction of the antenna according to the communication needs of ships, reduce signal interference, and improve communication quality.
