阅读说明：本技术 一种天线 (Antenna ) 是由 刘伟 肖伟宏 道坚丁九 于 2017-05-16 设计创作，主要内容包括：本发明实施例公开了一种天线,所述天线包括反射装置、工作频段位于第一预设频段内的至少两列辐射阵列和多个寄生辐射器,所述至少两列辐射阵列中的每列辐射阵列包括多个辐射单元,其中：所述至少两列辐射阵列中的每列辐射阵列沿所述反射装置长度方向电性设置在所述反射装置上,所述多个寄生辐射器设置于所述至少两列辐射阵列中的相邻两列辐射阵列之间。采用本申请,可以减小多阵列天线的水平面波宽。(The embodiment of the invention discloses an antenna, which comprises a reflecting device, at least two rows of radiation arrays and a plurality of parasitic radiators, wherein the working frequency range of the radiation arrays is positioned in a first preset frequency range, each row of radiation arrays in the radiation arrays comprises a plurality of radiation units, and the antenna comprises: each of the at least two rows of radiating arrays is electrically arranged on the reflecting device along the length direction of the reflecting device, and the plurality of parasitic radiators are arranged between two adjacent rows of radiating arrays in the at least two rows of radiating arrays. By adopting the method and the device, the horizontal plane wave width of the multi-array antenna can be reduced.)
