“…Since the emergence of waveguide structures, their simplicity, low conductor loss, and low radiation loss have continued to play a significant role in the realm of microwave/mmWave transmission lines. During the device design, rectangular waveguides often incorporate traditional reactance matching components like metal posts [1,2], diaphragms [3,4], and resonant windows [5,6]. With the advent of substrate integrated waveguide (SIW), a variety of dielectric substrates have replaced the air dielectric used in conventional rectangular waveguides [7].…”

This paper presents a method to realize equivalent lumped inductance/capacitance by adjusting the relative permittivity, diameter, and offset of the dielectric rod. The dielectric rod is used to replace the traditional reactance matching elements (metallic diaphragm, pin, and resonant window) in the substrate integrated waveguide, which avoids the problem of short circuit in the upper and lower metal plate of the substrate integrated waveguide, and has the advantage of high regulatory freedom, low radiation loss, and low crosstalk. Based on this method, three air rod filters are designed and verified by experiments. The three filters are designed based on the diameter and offset of a single dielectric hole and the offset of symmetrical dielectric rods. Compared with conventional filters, this method greatly adjusts the degree of freedom of media regulation in the substrate integrated waveguide. The experimental results are in good agreement with theoretical analysis and simulation results. It provides an effective platform for the design of substrate integrated waveguide functional lumped circuits.

A study of the diffraction of an electromagnetic wave on a dielectric coating with a diaphragm over an infinite waveguide antenna array has been carried out. The metal diaphragm is located at some distance from the surface of the antenna array. The influence of the geometric dimensions of a metal diaphragm and its distance from the grating surface on the modulus of the reflection coefficient of the incident wave in waveguides is investigated. Dielectric coatings with different values of the dielectric constant are considered.
