Abstract
A slow-wave substrate integrated groove gap waveguide (SW-SIGGW) is presented for the first time in this letter. The developed SW-SIGGW consists of three stacked substrate layers with different thickness, in which asymmetric half-height mushroom-type electromagnetic bandgap (EBG) structures are utilized for the convenience of tuning the heights of each layer. The slow-wave effect is achieved by loading periodical metallic via holes inside the groove gap waveguide in the bottom layer separating the magnetic and electric fields. In both lateral and longitudinal dimensions, 41% reductions are achieved through this new topology of SW-SIGGW, since the guided wavelength decreases significantly compared to the normal SIGGW of same width and height. A prototype of the SW-SIGGW is designed, manufactured, and measured. The simulated and measured results are in good agreement, proving the validity and feasibility of the design.
