本发明为辐射高频传输线。本发明特别适用于向移动的接收机传输高频讯号用的辐射高频传输线。为了从固定发射机向移动接收机传输高频讯号(或者相反),特别是在隧道内进行车站与列车上的接收机之间的无线电通讯时,可以使用不仅能低损耗地传输高频能量,而且同时能辐射的传输线。对于这种用途,以前是采用未屏蔽的对称高频线,例如“web”线路(“web”,lines)。但是,这种线路的损耗与辐射特性很受环境
The invention is a radiating high-frequency transmission line. The present invention is particularly suitable for radiating high frequency transmission lines for transmitting high frequency signals to mobile receivers. In order to transmit radio-frequency signals from the stationary transmitter to the mobile receiver (or vice versa), in particular when conducting radio communications between the station and the receiver on the train in the tunnel, it is possible to use not only low- And at the same time can radiate the transmission line. For this purpose, unshielded symmetrical high-frequency lines have previously been used, such as “web” lines. However, the loss and radiation characteristics of this line are very much affected by the environment
