Abstract
The invention discloses an exhaust pipe antenna which comprises an antenna cover and an antenna body. The antennal cover is in a circular tubular shape. The antenna body is arranged in the antenna cover. The antenna body comprises a reflecting plate, high-frequency vibrators and low-frequency vibrators. The high-frequency vibrators and the low-frequency vibrators are arranged on the top face of the reflecting plate. The low-frequency vibrators are arranged at intervals through the high-frequency vibrators. The number of the interval high-frequency vibrators is one or more. The high-frequency vibrators are embedded in the low-frequency vibrators. The reflecting plate is in a lengthwise shape. The lengthwise direction of the reflecting plate and the axial direction of the antenna cover are arranged to be in the same direction. The bottom face of the reflecting plate is arranged adjacent to part of the tube wall of the antenna cover. The horizontal width of the reflecting plate is smaller than the inner diameter of the antenna cover. The reflecting plate comprises a bottom plate and a side plate. The side plate is formed by the fact that the bottom plate is bent in a multi-level mode, so that the horizontal width of the bottom plate is narrowed, and the distance between the top face of the reflecting plate and the tube wall of the antenna cover on the opposite face is increased. The exhaust pipe antenna has optimized length and good electromagnetic wave radiance performance and can reduce suspect degree and lower mounting difficulty.
