室外高增益宽频天线

Outdoor high gain wide frequency antenna (WFA)

Abstract

本实用新型提供了一种室外高增益宽频天线,包括:辐射振子、反射板、连接辐射振子与反射板的导柱、馈电针、馈电针定位圈、馈线压线扣、射频线及射频头;辐射振子通过导柱固定在反射板上,射频线通过馈线压线扣扣压在反射板上,馈电针通过馈电针定位圈对辐射振子进行馈电,射频线的另一端与射频头连接。本实用新型由于采用了射频局部短路技术和圆形最大面曲流辐射技术,有效减少了辐射体的面积;同时也减小了接地平面的面积,使得天线整体结构更加紧凑,缩小了整个天线的体积,节约了生产成本。
The utility model provides an outdoor high gain wide frequency antenna (WFA) which comprises a radiation oscillator, a reflection plate, a guide post connecting the radiation oscillator with the reflection plate, a feed needle, a feed needle positioning ring, a feeder wire pressing fastener, a radio frequency (RF) line and an RF head, wherein the radiation oscillator is fixed on the reflection plate through the guide post, the RF line is buckled and pressed on the reflection plate through the feeder wire pressing fastener, the feed needle feeds the radiation oscillator through the feed needle positioning ring, and the other end of the RF line is connected with the RF head. In the outdoor high gain WFA, the RF local short circuit technology and the round maximum face meandering radiation technology are adopted so that the area of a radiating body is effectively reduced, the area of the grounding plane is reduced simultaneously, therefore, the entire structure of the antenna is more compact, the volume of the entire antenna is reduced, and the production cost is saved.
