Claim:
1. A folded corrugated substrate integrated waveguide comprising: a first conductor plate comprising top stubs formed lengthwise on both sides; a first dielectric substrate whose top surface is attached to a bottom surface of the first conductor plate; a second conductor plate whose top surface is attached to a bottom surface of the first dielectric substrate; a second dielectric substrate whose top surface is attached to a bottom surface of the second conductor plate; and stub conductors disposed in two rows in parallel with a certain interval and attached to a bottom surface of the second dielectric substrate, wherein the respective stub conductors of the two rows are electrically connected to the top stubs of the first conductor plate, whose locations correspond thereto, through via holes which vertically penetrate the first dielectric substrate, the second conductor plate, and the second dielectric substrate, wherein the top stubs and the respective stub conductors form open circuit stubs having a length of λ/4.
