In recent years, the hybrid branch‐line coupler has attracted much attention due to its
appealing features such as of low cost and ease in fabrication for wireless communications …

A complementary split-ring resonator (CSRR)-loaded substrate-integrated waveguide (SIW)
phase shifter and its application to a six-port junction is presented and demonstrated in this …

This letter presents a compact substrate-integrated waveguide (SIW) six-port junction. It
consists of two-plane power dividers, two cruciform quadrature hybrid couplers, and one self …

In this study, a novel coupling structure based on half‐mode substrate‐integrated
waveguide (HMSIW) is proposed with a small size and broad bandwidth. The HMSIW …

In this paper, an accurate calibration and calculation method of six-port circuit is proposed
and tested in a microfluidic sensing system. Based on the Levenberg-Marquardt algorithm, a …

A compact broadband substrate integrated waveguide (SIW) six-port junction based on a
novel topology and its application in angle-of-arrival (AoA) finding system are proposed in …

The emerging fifth-generation (5G) wireless and mobile communications demand high-
performance phase shifters to enable the multi-channel transmit/receive systems with phase …

In this paper, a slotted substrate integrated waveguide (SIW) is used to create a balanced
phase shifter with wideband common-mode (CM) suppression. Differential-mode (DM) …

An X‐band substrate integrated waveguide (SIW) balun, based on a Y‐type divider with
enlarged bandwidth, is presented in this study. In most SIW Y‐type dividers, the undesired …

This paper reports the design and development of a miniaturized substrate integrated
coaxial line (SICL) based branch line coupler operating at 5 GHz with broad out of band …
