The invention discloses a high-gain ultra-wideband unmanned aerial vehicle antenna, which comprises a dielectric substrate, and a first radiator and a second radiator printed on the front surface of the dielectric substrate, and a feed gap exists between the first radiator and the second radiator. According to the invention, two times of accurate impedance matching are realized through the first radiator, higher impedance bandwidth is realized, and the adaptability and flexibility of the antenna are improved. Besides, the first radiation patch of the first radiator adopts a trident-shaped design, so that a unique radiation mode and performance are provided for the antenna, and the gain and directivity of the antenna are improved. Through the specific layout of the first radiator and the second radiator, the uniform distribution of current in a working frequency band is realized, the antenna is endowed with an omnidirectional radiation characteristic, and the omnidirectional radiation characteristic is crucial to the communication of the unmanned aerial vehicle in various directions.

    本发明公开一种高增益超宽带无人机天线,包括介质基板,以及印制于介质基板正面的第一辐射体、第二辐射体;所述第一辐射体、第二辐射体间存在馈电缝隙。本发明通过第一辐射体实现了两次精确的阻抗匹配,实现了更高的阻抗带宽,提高了天线的适应性和灵活性。另外,第一辐射体的第一辐射贴片采用三叉戟状设计,为天线提供了独特的辐射模式和性能,有助于提高天线的增益和方向性。通过第一辐射体和第二辐射体的特定布局,实现了工作频带内的电流均匀分布,赋予天线全向辐射特性,这种全向性对于无人机在各种方向上的通信至关重要。
