The use of substrate integrated waveguides (SIW) for microwave and millimeter wave
integrated components has increased dramatically over the last decade. They mimic the …

A wideband phase shifter in U-band realized in groove gap waveguide (GGWG) technology
is presented as a good solution to be integrated in antenna feed structures. The GGWG is …

A compact phase shifter using substrate integrated waveguide (SIW) with two slots is
proposed in this letter. The wideband phase shift is mainly caused by the opposite phase …

This article analyzes thoroughly the dispersion and filtering features of periodic holey
waveguides in the millimeter-wave frequency range. Two structures are mainly studied …

This letter presents the design and performance of a planar narrow bandwidth bandpass
filter with high quality factor. The structure is composed of an empty substrate integrated …

This letter presents a low-cost, low-profile, and high-performance Ka-band continuously
tunable substrate integrated waveguide (SIW) phase shifter. The proposed phase shifter …

In this letter, a compact quadrature coupler based on a circular sector patch element with
metallic posts loading along the edge, is proposed to provide a wide range of coupling …

In the RF (Radio Frequency) front-end of a communication system, bandpass filters (BPFs)
are used to send passband signals and reject stopband signals. Substrate-integrated …

This paper proposes a wideband compact equal-length phase shifter based on the hybrid
half-mode substrate integrated waveguide (HMSIW) and spoof surface plasmon polariton …

A compact broadband phase shifter based on the half-mode substrate-integrated waveguide
(HMSIW) is proposed in this letter. By etching interdigital capacitor or adding blind holes and …
