The patent describes a waveguide launcher apparatus for coupling a coaxial transmission line to a waveguide array antenna element. The waveguide launcher apparatus uses its short depth to achieve the desired match between the coaxial connector and free space. The launcher apparatus has an L shape which performs as a matching element and as an adaptor between the coax transmission line and wave guide sections.
