Disclosed is a dual transit structure for a millimeter wave receiver, which comprises: a suspended strip line (SSL) unit having a dielectric substrate disposed in a cavity formed inside a metal case and an SSL formed on one surface of the dielectric substrate, wherein the SSL is a metal first signal transmission line; a primary transit unit disposed on one end of the SSL unit to be vertically coupled to a waveguide antenna of a millimeter wave seeker and having a matching patch of a predetermined pattern formed on the dielectric substrate to transit a received signal transmitted from the waveguide antenna to the SSL unit; and a secondary transit unit formed by tapering the width of the SSL in the SSL unit to the width of a second transmission line to transit the received signal to a microstrip or a CPW having the second signal transmission line and a ground plane formed on the dielectric substrate outside the metal case on the other end of the SSL unit, wherein the width of the second signal transmission line is different from the width of the first signal transmission line. |
