coupling or slot-coupling just as with resonant cavities. Figure 114 shows
an example of loop coupling into a waveguide.
Loop Coupling into a Waveguide.
c. Now let's see how energy is coupled out of waveguide.
used depends upon the device to which the waveguide is coupled.
16. Waveguides are coupled to one of three devices.
a. The three principal uses of waveguide are as follows:
