Rectangular Waveguide TE<sub>10</sub> to Substrate Integrated Waveguide TE<sub>20</sub> Probe-less Mode Converter for Planar Terahertz Applications
This paper presents a novel design of mode converter for planar terahertz (THz) applications, which converts the rectangular waveguide (RWG) TE<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">10</inf> mode to substrate integrated waveguide (SIW) TE<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">20</inf> mode. Unlike other converters that use probes for impedance matching during the conversion, this converter utilizes the stepped width of SIW’s top metallic layer to match the impedance during the transition. A back-to-back converter is designed and simulated to cover the frequency range of 1.25 - 1.32 THz, showing a return loss of 15 dB and an average insertion loss of 1.28 dB for the whole bandwidth.
