Differential Bi-Level Microstrip Directional Coupler with Equalized Coupling Coefficients for Directivity Improvement
In this paper, a bi-level microstrip differential directional coupler has been investigated. It has been shown that the equalization of coupling coefficients can be successfully made with the use of appropriate dielectric stack-up and conductor geometry. The application of additional top dielectric...
