Abstract:
1. A surface mount module adapted for transfer of a microwave signal between the surface mount module and a motherboard, the surface mount module comprising: a substrate; a first microstrip conductor on a first side of the substrate; and a second microstrip conductor on a second, opposite side of the substrate, wherein the first microstrip conductor and the second microstrip conductor are connected with a connection through the surface mount module, wherein the connection comprises the first microstrip conductor being connected to a first foil of electrically conducting material coated on the first side of the substrate, wherein the first foil comprises an approximately rectangular shape having first, second, third, and fourth sides, wherein the first and third sides are opposite one another, and the first microstrip conductor is in direct contact with the first foil, wherein the first foil is surrounded by electrically conducting trenches running through the substrate from the first side to the second side of the substrate forming a substrate integrated waveguide, wherein the trenches on the second side surround a second foil of electrically conducting material coated on the second side of the substrate and connected to the second microstrip conductor, and wherein the second foil comprises the approximately rectangular shape having first, second, third, and fourth sides, wherein the first and third sides are opposite one another, and the second microstrip conductor is in direct contact with the second foil, and wherein the trenches are located only along the first side and the third side of the first foil, wherein the first microstrip conductor is located at the second side of the first foil, and wherein the trenches are located only along the first side and the third side of the second foil, and wherein the second microstrip conductor is located at the second side of the second foil.
