Abstract
A directional coupler includes a dielectric substrate having at least an input terminal and an output terminal on a surface thereof, a main line disposed in the dielectric substrate and extending between the input terminal and the output terminal, a first coupling line for monitoring a level of an input signal which is input through the input terminal, the first coupling line being disposed in the dielectric substrate and having an end electrically connected to a first terminating resistor, and a second coupling line for monitoring a level of a reflected signal which is input through the output terminal, the second coupling line being disposed in the dielectric substrate and having an end electrically connected to a second terminating resistor.
