Analysis and Design of a One-twelfth Wavelength Three-section Directional Coupler

This article describes the design and development of a three-section 10 dB backward wave directional coupler at Ku-band. The approach demonstrates a two-third reduction in the line length of each section, compared to the traditional approach. The simul...
Presently, the trend in satellite communication is focusing on high frequencies with wider user bandwidths. Directional couplers are an integral part of onboard as well as ground applications, either for combining or splitting power. Planar directional couplers, using coupled microstrip lines, are commonly used for different coupling values.1 Couplers...
