Compact 3‐dB directional coupler design based on substrate integrated dual‐strip coaxial line
IET Microwaves, Antennas & Propagation, 2022 A novel compact 3‐dB directional coupler design based on the substrate integrated dual‐strip coaxial line (SIDSCL) is presented. The SIDSCL differs from the conventional substrate integrated coaxial line (SICL) in that the former possesses two central ...
