Abstract This study reports a class of balanced‐to‐unbalanced (BTU) and balanced‐to‐balanced (BTB) filtering rat‐race couplers (FRCs) based on multilayer substrate integrated waveguide (SIW) cavities. Input and output ports can perform the

A novel Gysel power divider, which can be fabricated without a need for any high-impedance transmission-line section (TL), even for the power-division ratios higher than 15 dB, is presented. To derive its design formulas, a new study on the conventio

Coupled-line ring hybrids (CRHs) are presented for arbitrary circumferences and for arbitrary power-division ratios. They each consist of three single transmission-line sections and a set of coupled transmission-line sections with or without two iden

The paper presents a compact broadband rat-race coupler for the first time designed and realized in a mul- tilayer microstrip technology. To achieve both broad operational bandwidth and a compact size the 270◦ transmission line of a conventional ra
