自馈相四臂螺旋GPS卫星信号接收天线

本发明公开了一种自馈相四臂螺旋GPS卫星信号接收天线，包括：馈电杆、插座、介质套、安装法兰、馈管、螺旋线、内导体；螺旋线的两端与馈管焊接在一起；馈管的后端插入安装法兰的圆孔中；位于馈管中心的内导体，左端焊接在馈管上，右端通过螺纹连接到馈电杆；馈电杆靠插座内的介质套固定在插座中；插座是天线的馈电端口，连接高频电缆实现给天线馈电。本发明简化了系统结构，提高了系统可靠性。

Self-feedingphase four-arm spiral GPS satellite signal receiving antenna

Theinvention discloses a self-feeding phase four-arm spiral GPS satellite signalreceiving antenna. The self-feeding phase four-arm spiral GPS satellite signalreceiving antenna comprises a feed pole, a socket, a dielectric sleeve, amounting flange, a feed pipe, a spiral line and an inner conductor. The twoends of the spiral line and the feed pipe are welded together. The rear end ofthe feed pipe is inserted into a circular hole of the mounting flange. The leftend of the inner conductor located at the center of the feed pipe is welded to thefeed pipe, and the right end of the inner conductor is connected to the feedpole through a thread. The feed pole is fixed in the socket through the dielectricsleeve in the socket. The socket is a feed port of the antenna and is connectedwith a high frequency cable to achieve feed to the antenna. According to the self-feedingphase four-arm spiral GPS satellite signal receiving antenna, the systemstructure is simplified, and system reliability is improved.
