一种用于电力230MHz无线通信设备的小型天线
摘要：
本实用新型公开了一种用于电力230MHz无线通信设备的小型天线，包括：由金属导线绕成的螺旋状天线、金属反射板、同轴线，所述同轴线穿过所述金属反射板与所述螺旋状天线相连；所述螺旋状天线由所述同轴线馈电；所述金属反射板位于馈电端；所述金属反射板与所述螺旋状天线的螺旋轴线垂直。本实用新型的用于电力230MHz无线通信设备的小型天线，将轴向模螺旋天线与锥面螺旋天线结合起来，减小了天线尺寸,增加了天线带宽。螺旋天线以其良好的辐射特性、小体积、频带扩展容易实现的特性成为外置天线的主流。该实用新型的天线形状是扁平特性的，同时此类天线的设计具有较强的灵活性，应用会越来越多。结构简单，体积小，易于安装。
摘要（英）：

The utility model discloses a small -size antenna for electric power 230MHz wireless telecom equipment, include: by plain conductor wound heliciform antenna, metal reflecting plate, coaxial line, the coaxial line passes the metal reflecting plate with the heliciform antenna links to each other, the heliciform antenna by the coaxial line feed, the metal reflecting plate is located the feed end, the metal reflecting plate with the axis of screw of heliciform antenna is perpendicular. The utility model discloses a small -size antenna for electric power 230MHz wireless telecom equipment combines axial mode helical antenna and conical surface helical antenna, has reduced the antenna size, has increased the antenna bandwidth. Helical antenna becomes external antenna's mainstream with its good radiation characteristic, little volume, the easy characteristic that realizes of bandspreading. The utility model discloses an antenna shape be flat characteristic, the design of this type of antenna simultaneously has stronger flexibility, it can be more and more to use. Simple structure, it is small, easily installation.
