This paper treats a new substrate integrated waveguide composed of a honeycomb substrate having a number of small holes (air-filled posts) drilled vertically through the conductor layers of both sides. If the diameter of air posts is sufficiently small in comparison with an operation wavelength and the conductors have a certain thickness, the radiation loss from the small holes can be negligible. In addition, since it can be assumed that the direction of the electric field in the honeycomb substrate is nearly vertical to it, the effective permittivity is approximately derived from the ratio of area occupied by the air-filled posts to the remainder dielectric area. Such a honeycomb substrate integrated waveguide (HCSIW) suffers from the radiation loss from the small holes and the additional conductor loss caused by reduction of conductor area, while the dielectric loss reduces by replacing a part of the lossy dielectric with a lossless air region. First, we calculate the above various losses for a commercial substrate with several conductor thickness. As a result, the attenuation constant of HCSIW is equal to or less than the conventional SIW due to the cancellations of the losses.
Next, we show a design methodology of SIW passive components by arranging the dielectric constant distribution in a circuit by the use of the air-filled posts. As an example, an SIW right-angle corner is dealt with, and a broad-band matching is realized by placing the air-filled posts appropriately to the junction area of the corner. The analysis and design are performed by a commercial HFSS electromagnetic simulator. Moreover, HCSIW can be easily fabricated from a commercial substrate with a PCB prototyping machine. |
