Abrégé
(EN)
The invention discloses a millimeter-wave low-profile broadband antenna, comprising the following three-layer structures arranged in order from top to bottom: a first layer structure comprising a metal patch structure and two metal strip resonators, the metal patch structure being positioned between the two metal strip resonators; and a second layer structure comprising a metal strip resonator anda metal strip resonator. The second layer is a large metal formation with a pair of circular cracks; A third layer structure including a feeding structure connected to the two metal strip resonatorsthrough a pair of metal vias through which the pair of circular slots are pierced. The invention solves the problem that the traditional design technology requires high profile height, and realizes the wideband coverage performance of the antenna on the basis of low profile. Moreover, the metal patch structure and the two metal strip resonators are arranged in the same layer, and the single layerstructure is adopted, that is, only one layer of dielectric substrate is needed above the metal ground of the antenna, which effectively reduces the design and processing cost, realizes a wide spectrum bandwidth in a low-cost manner, and has good radiation performance in the frequency band.

本发明公开了一种毫米波低剖面宽带天线,包括从上至下顺序设置的以下三层结构:第一层结构,包括金属贴片结构和两个金属带条谐振器,所述金属贴片结构位于所述两个金属带条谐振器之间;第二层结构,为开设了一对圆形缝隙的金属大地层;第三层结构,包括馈电结构,所述馈电结构通过穿设所述一对圆形缝隙的一对金属通孔与所述两个金属带条谐振器连接。本发明解决了传统设计技术对剖面高度要求较高的问题,在低剖面的基础上,实现了天线的宽带覆盖性能;再者,将金属贴片结构和两个金属带条谐振器布置在同一层,采用单层结构,即天线的金属大地以上仅需一层介质基板,有效降低了设计加工成本,以低成本方式实现了较宽的频谱带宽,频带内具有良好的辐射性能。
