“…The selection of dielectric rods is typically based on relative permittivity and loss tangent. The addition of a dielectric rod alters the relative permittivity of the substrate, consequently affecting the resonant frequency of the structure [26,27]. By incorporating and removing dielectric rods with different relative permittivity values, multiple responses can be achieved within the same structure.…”

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.
