A Cost-effective D-band Multi-layer Rectangular Waveguide Transmission Line Based on Glide-Symmetric EBG Structure

• An air-filled multi-layer waveguide (MLW) transmission line with a novel architecture for high-frequency applications is presented. A rectangular waveguide transmission line is formed by stacking several thin metal layers without any electrical and galvanic contact requirement among the layers. A glide-symmetric electromagnetic band gap (EBG) structure is used to package the layers and eliminate any possible leakage. A back-to-back straight line with two right-angle bends is manufactured by use of chemical metal etching, a low-cost and high-precision fabrication technique. The fabricated prototype shows high performance with low measured transmission loss of 0.17 dB/cm at D-band (110 to 170 GHz). The proposed multilayer waveguide (MLW) has the great advantages of low-cost and easy fabrication with a low transmission loss, even for frequencies beyond 100 GHz. The proposed concept could be a good approach to design high-performance passive waveguide components, and also active and passive components integration in mass production at the millimeter wave frequency band.
