Parametric Study of Different Shapes-Slotted Substrate Integrated Waveguide for Wideband Applications

Abstract

On the way to design Substrate Integrated Waveguide Bandpass Filter (SIW-BPF) for wideband applications a parametric study of the slot geometry etched on a SIW structure is the preliminary step to design such filter. Three different structures, namely, H-Slotted, T-Slotted, and U-Slotted SIW is investigated in order to examine the effect of altering different geometrical parameter of the unit on its response. H-Slotted Electromagnetic Band Gap (EBG) shows the highest Fractional Band Width (FBW), which is about 90% compared to the others, consequently it could be used to design a wideband SIW-BPF.

A NOVEL DUAL-BAND PRINTED SIW ANTENNA DESIGN BASED ON FISHNET & CCRR DGS USING MACHINE LEARNING FOR KU-BAND APPLICATIONS

“…As reported in [24,25], the SIW was also used for wideband Band Pass Filter (BPF) designs, and the equivalent dimensions of the SIW as illustrated in Figure 1 are determined using the width (W ) and length (L) of the classical rectangular waveguide. The diameter of the holes (d) and the spacing (p) between the holes can be determined from the following equations: where f TE10 is the cut-off frequency of the dominant mode.…”

Design and Fabrication of Compact MIMO Array Antenna with Tapered Feed Line for 5G Applications

“…As demonstrated in [33], where a monopole antenna array operating at 28 GHz and with a gain of 8 dB is built, monopole antennas were considered as a potential for 5G communication systems. Recently, researchers and antenna designers have employed many technologies, including Defected Ground Structures (DGS), Frequency Selective Surfaces, and EBG as given in [34][35][36][37][38][39][40][41][42], to increase overall performance enhancement, miniaturization, and multi-band microwave and mm-Wave component design.…”
