1. A signal transmission channel comprising:
a substrate integrated waveguide configured for use as a signal transmission channel; a first interface configured to connect with receiver microstrip lines, the first interface including a first tapered portion and a first slot surrounding the first tapered portion; a second interface configured to connect with transmitter microstrip lines, the second interface including a second tapered portion and a second slot surrounding the second tapered portion; and an upper sheath and a lower sheath configured to connect the substrate integrated waveguide and the first interface and/or the second interface, the upper sheath at least partially extending toward the lower sheath to form a portion of at least one open slot, the substrate integrated waveguide at least partially received within the at least one open slot, wherein the lower sheath extends up to an end portion of the transmitter microstrip lines, and the upper sheath extends to partially receive the transmitter microstrip lines.
