Abstract: In this paper, design principles for implementation of broadband T-type and Y-type power divider based on Substrate-Integrated Waveguide (SIW) technology has been presented. Different design curves have been developed based on simulation results and are used to implement 1×2 power dividers of Y-type and T-type. Finally, by cascading T-type and Y-type stages a 1×4 Power divider of equal division is designed and simulated. The proposed design shows a broad bandwidth (−20 dB) of 18.3% and insertion-loss Bandwidth (1%) of 17.86%.

13 May 2015TL;DR: In this paper, a detailed characterization of multilayer compact Substrate Integrated Waveguide (SIW) series-series slot coupler is presented, where the coupling slots for a range of tilt angle, frequencies and resonant length are presented.
Abstract: In this paper, a detailed characterization of multilayer compact Substrate Integrated Waveguide (SIW) series-series slot coupler is presented. Behavior of coupling slots for a range of tilt angle, frequencies and resonant length are presented. The proposed design principle has been described with the help of the characterization results of the double layered cross coupled SIW slot coupler. An application of the proposed SIW coupler as 1 to 2 power divider is also presented. The multilayer behavior and SIW technique make the structure compact which occupies less space as compared to traditional power dividers. The proposed design works for the bandwidth of 474 MHz (4.65% for −20 dB) and can be used as a feeding network for the SIW based waveguide slot array antenna.

TL;DR: In this paper, the phase shifters consist of a SIW section with rows of metallic posts used for phase shifting are inserted at the output ports, and proper phase shifting in this configuration is achieved by changing the diameter and position of these metallic posts.
Abstract: In this paper, 1 × 2 Y-type and 1 × 4 cascaded SIW power divider based phase shifters are presented at X-band. The proposed phase shifters consist of a SIW section with rows of metallic posts used for phase shifting are inserted at the output ports. The proper phase shifting in this configuration is achieved by changing the diameter and position of these metallic posts. There is a shift in the region of operation of the phase shifter as the diameter and the position of the via changes. The proposed geometry is designed and optimized by numerical simulations (HFSS) and fabricated prototype is validated through experiments. Simulated and measured results of proposed structures are in good agreement. For two output phase shifter consecutive ports have the phase shift of 152° and for four output of 40° are achieved. The S 11 is below −15 dB over the frequency band of 9.5 to 11.4 GHz with the percentage bandwidth of 17% is obtained.

TL;DR: In this paper , the authors proposed a design methodology by which planar power splitters with arbitrary output power levels can be designed in light of very simple perturbations, i.e., vias.
Abstract: Since the recent on-demand applications need more sophisticated circuits and subsystems, components with configurable capabilities attract attention more than before in commercial systems, specifically the fifth generation (5G). Power dividers play a crucial role in 5G phased array systems, and their role becomes more significant if the output powers ratio is adjustable. Here, we suggest a design methodology by which planar power splitters with arbitrary output power levels can be designed in light of very simple perturbations, i.e., vias. Through our design procedure, we find an optimized pattern for hybrid vias-some of them are made of PEC, and others are dielectric, e.g., air, high-permittivity materials. Thanks to deep neural networks, we demonstrate that this technique can be employed to design power splitters whose output ports have different amplitudes. In light of the proposed method, we fabricated and measured a 4-way power divider realizing Chebyshev coefficients for sidelobe reduction of a 4-element array at 28 GHz as a proof-of-concept. We believe that this methodology in which hybrid perturbation is the key spot paves a way to implement complex functions in various platforms and other structures, e.g., SIWs, ridge waveguides, rather than the one we investigated (planar/microstrip).

TL;DR: A novel concept to implement millimeterwave substrate integrated waveguide-based circuits for chipless identification application has been demonstrated and the complete design has been realized in K band making physical size of the circuit very small which makes it attractive for practical application.
Abstract: In this paper, a novel concept to implement millimeterwave substrate integrated waveguide-based circuits for chipless identification application has been demonstrated. The proposed design utilizes a pair of compact half mode SIW cavity to encode the interrogating signal and resend the signal through the open-end aperture of the cavity. Thus, the encoding resonator itself has been utilized as radiator (a)1 of the interrogating signal which helps to improve the compactness of the design. The complete design has been realized in K band making physical size of the circuit very small which makes it attractive for practical application.

TL;DR: In this article, a numerical multimode calibration procedure is proposed and developed with a commercial software package on the basis of a full-wave finite-element method for the accurate extraction of complex propagation constants of the SIW structure.
Abstract: The substrate integrated waveguide (SIW) technique makes it possible that a complete circuit including planar circuitry, transitions, and rectangular waveguides are fabricated in planar form using a standard printed circuit board or other planar processing techniques. In this paper, guided wave and modes characteristics of such an SIW periodic structure are studied in detail for the first time. A numerical multimode calibration procedure is proposed and developed with a commercial software package on the basis of a full-wave finite-element method for the accurate extraction of complex propagation constants of the SIW structure. Two different lengths of the SIW are numerically simulated under multimode excitation. By means of our proposed technique, the complex propagation constant of each SIW mode can accurately be extracted and the electromagnetic bandstop phenomena of periodic structures are also investigated. Experiments are made to validate our proposed technique. Simple design rules are provided and discussed.
