“…One of these is based on several phase channels made by SIW resonators loaded with additional metallic posts, to design a phase shifter with 10% fractional bandwidth and the other design proposes a compact phase shifter using omega particles; thus, providing bandwidths of around 55% for 90° and 45° versions of the phase shifter, with the accuracy of 3° and 60% with the accuracy of 2.5°. A broadband magic T , X‐band SIW attenuator and circulators were also implemented and experimentally verified. The analysis of loaded SIW attenuators was presented in .…”

The use of substrate integrated waveguides (SIW) for microwave and millimeter wave integrated components has increased dramatically over the last decade. They mimic the performance of conventional metallic waveguides and they are fabricated using printed circuit boards using the top and bottom metallization with two rows of vias forming the side walls. This creates a low profile, compact, and light weight alternative to conventional metallic waveguides, and they allow a direct interconnection with printed circuit boards and active components. This article reviews the fundamental theory, documents the research that has been performed over the past decade, and summarizes progress up to the recent state-of-the-art including novel SIW structures for passive circuits and antennas as well as new applications for reconfigurable and printed circuits using SIW technology.

“…Similarly, three shunt PIN diodes are used in a branch-line directional coupler for a variable attenuator with a large circuit size. 27 In, [28][29][30][31] substrate integrated waveguide attenuators were presented. Despite significant research in the field of analog/digital attenuators, the previously presented works [19][20][21][22][23][24][25][26][27][28][29][30][31] are mainly focused on amplitude control rather than simultaneous flat amplitude error and insertion phase variations minimization, which are significantly essential for phased array and beamforming systems in wireless communication systems.…”

This paper presents a design of an analog variable attenuator with simultaneous minimized flat amplitude error and insertion phase variation over a wide bandwidth and high attenuation range. The parasitic of PIN is compensated with series transmission lines loaded and shunt capacitors to achieve minimum flat amplitude error and insertion phase variation. Mechanism for simultaneous reduction in flat amplitude error and phase variations is obtained by developing an analytical design equation using the PIN diode equivalent circuit model. For the experimental validation, two kinds of proposed attenuators are designed and measured over 1 GHz bandwidth at a center frequency (f 0 ) of 3.5 GHz. The measurement results are consistent with the simulation results. From the experiments, design-I provides an attenuation variation of 0.9 dB to 20 dB with a maximum flat amplitude error of 0.65 dB and insertion phase variation of 5.70 over 1 GHz bandwidth. Similarly, the design-II provides an attenuation variation of 1.06 dB to 20 dB with a maximum amplitude error of 0.49 dB and insertion phase variation of 3.19 over the same 1 GHz bandwidth.
