A study aimed at identifying the effect of substrate parameters such as dielectric permittivity and thickness on the characteristics of directional couplers, whose dimensions are reduced by means of compact structures. It was found that with the increase in the thickness of the substrate in a compact coupler increases the frequency band and the degree of miniaturization, and with increasing dielectric constant Vice versa.
