Wave guide or waveguide. This is a kind of transmission lines - used to send a wave, microwave, generally has a circular pipe, square pipe. But to do this and it is made of copper or aluminium.Cause of RF cable Acting pipe because. Microwave frequency is very high to travel well at the surface of the conductor if use the line signal. General will cause a loss of energy.The lowest frequency that can be used with the waveguide is called frequency cut off if the frequency higher than the frequency cut of to be able to go on the waveguide. The lower frequency than this will not be able to travel on the waveguide.To travel by the reflection of the pipe wall. And travel along the length of the waveguide. High frequency and can travel far superior to low frequency
