Patent ID: 7915981

Claim:
A coaxial-to-microstrip transition comprising: a microstrip line including: a first dielectric having a first primary face and a second primary face opposite the first primary face, a conductive strip disposed on the first primary face of the first dielectric, and a ground plane disposed on the second primary face of the first dielectric; and a coaxial-line assembly extending along an axis transverse to the ground plane and having an end adjacent to the microstrip line, the coaxial-line assembly including: an outer conductor extending along the axis to the ground plane, an end of the outer conductor being in contact with the ground plane, and an inner conductor extending along the axis past the ground plane and being electrically connected to the conductive strip; wherein the ground plane extends to a position between the outer conductor and the inner conductor on only a first side of the coaxial-line assembly proximate the conductive strip, and wherein the microstrip line further includes a first aperture extending through the ground plane and through which the inner conductor extends, the aperture extending beyond the outer conductor on a second side of the coaxial-line assembly distal the conductive strip.
