As shown, the strip width, w, has a smaller influence on the dominant mode E11z, but plays a major role in controlling the single-mode bandwidth. Furthermore, the upper bandwidth limit is shifted to a little lower frequency when the isolating film is used. Then, the propagation characteristics of LTCC-based SIIGs are investigated. 45 present the normalized phase constants versus different dielectric strip widths and thicknesses at different frequency bands. The larger strip width and thickness lead to a larger phase constant.
Influences of the distance between neighboring metalized vias s and the diameter of the metalized vias d on SIW APHC will be investigated within these limitations. 20 gives a series of equal APHC lines. Each one shows an APHC value at a specific frequency. The APHC decreases with the operating frequency, following the arrow. When a/d is equal, a larger d increases the APHC. When d is equal, a larger a/d increases the APHC. 21 shows the APHC versus d/s with different diameters of the metalized via.
Even their dielectric losses are comparable. 3 SUBSTRATE INTEGRATED NONRADIATIVE DIELECTRIC GUIDE A rectangular dielectric slab sandwiched between two metallic plates can be used to synthesize the NRD guide. Its operating frequency range is determined by the spacing between the metallic plates. The slab width is also important to determine the operating bandwidth. 49 Configuration of a typical SINRD guide. 49, the SINRD guide  is an integrated and planar structure derived from the conventional NRD guide.
