Substrate Integrated Waveguide Power Divider, Circulator and Coupler in [10-15] GHZ Band

Abstract

The Substrate Integrated Waveguide (SIW) [9] has been studied. Figure 1 illustrate the RSIW which is designed from two rows of periodic metallic posts connected to higher and lower planes mass of dielectric substrate. Figure 2 and 3 shows the similarity of the geometry and the distribution of the electric field between (RSIW) and the equivalent rectangular wave guide [2] [3]. In this paper, [10][11][12][13][14][15] GHz band RSIW components are proposed and optimized. They are essential for many microwave and millimeter-wave integrated circuits and telecommunication systems. FUNDAMENTAL RSIW CHARACTERISTICSFor designing (RSIW) (Figure 1) many physical parameters are necessary as d the diameter of holes stems, p the spacing between the holes and W spacing between the two rows of holes. Two rows of holes are drilled and metalized, making contact between the two metal planes of the dielectric substrate, permitting propagation for all modes TE n0 [5]. The lines of current along the lateral walls of the RSIW are vertical, the fundamental TE10 mode may be propagated. Electrical performance of RSIW and a conventional rectangular waveguide filled with dielectric of width W [4] are similar.

Substrate Integrated Waveguide (SIW) Coupler on Green Material Substrate for Internet of Things (IoT) Applications

“…A tapered microstrip line is important to match the SIW with 50Ω transmission lines impedance. By following the guidelines given in [18] [19], the initial value of tapered width (Wt) and tapered length (Lt) shown in Fig. 4 are determined [9][19] using expression (8) to (11).…”

“…Substrate Integrated Waveguide (SIW) is a techniques can achieve a little loss in the highest frequency that can come up with very good frequency performance on low dielectric permittivity substrate materials compared to coplanar waveguide (CPW) and planar circuits in microstrip [4] [5]. The development of Substrate Integrated Waveguide (SIW) methods build-up from double rows of conducting via (slots) filled in a dielectric substrate to connect two plates (copper planes) of substrate [6] [7].…”
