Dual-frequency-band omni-directional array antenna

The embodiment of the invention discloses a dual-frequency-band omni-directional array antenna. The antenna comprises a plurality of oscillators and a plurality of parasitic units, wherein the oscillators and the parasitic units are arranged on a micro-strip plate; the oscillators and the parasitic units are alternately arranged in the length direction of the antenna to form two rows of antenna units; the two spaced oscillators in each row of antenna are connected through a feed connector, and feeding of the oscillators is achieved. According to the technical scheme, double-frequency operationof the antenna is achieved by adding the parasitic units, and the parasitic units are alternately placed on the structure, so that the antenna has the advantages of being simple in structure, low inweight, low in machining cost and the like. 本申请实施例中种双频段全向阵列天线，该天线包括：设置在微带板上的多个振子和多个寄生单元；所述振子和寄生单元沿天线长度方向交替布置，形成两列天线单元；每列天线单元中相隔两个振子之间通过馈电连接器连接，实现对振子的馈电。本申请所述技术方案该天线通过增加寄生单元实现了双频工作，将寄生单元交替放置在结构上具有结构简单、重量轻、加工成本低等优点。
