The ridge waveguide, which is a rectangular waveguide with one or more metal inserts
(ridges), is an important transmission line in microwave engineering, through which many …

Microwave heating has attracted wide attention in fiber dyeing, refining, drying and
modification due to its energy saving and environmental protection. However, effectively …

The utilization of planar millimeter-wavelength whispering gallery dielectric resonator modes
for the design of W-band directional filters and power combiners is studied. The device …

This paper presents a novel transition between a microstrip line and a substrate integrated
waveguide (SIW) in a multilayer substrate design environment. In order to achieve a low …

This article presents a comprehensive treatment and a systematic design methodology of
filtering couplers based on canonical coupled resonator networks. A theoretical framework …

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

A novel band-pass filter topology in waveguide technology is presented in this work. The
proposed filter design is based on a periodic structure that uses modified sections of a single …

Brief expressions of eigenvalue problems, nornral modes, and electric-field profiles for all
odd TE and TM modes of ridged waveguides, and the guide wavelength and characteristic …

This study was conducted to design a wideband septum polariser as a feeder of the antenna
to generate right‐hand circular polarisation (RHCP) and left‐hand circular polarisation …

This paper presents, to the best of the authors' knowledge, the first realizations of the Gysel-
type power combiner/divider in ridge waveguide technology with two different …
