Abstract: One example includes a system is comprised of an elongated transmission line and as module. The elongated transmission line includes an arrangement of transmission line couplers distributed along its length at spaced apart locations. The module has an outer surface and is comprised of a transmitter, and a transmitter coupler. The transmitter transmits a radio frequency signal. The transmitter coupler is on the outer surface of the module, electrically connects with the transmitter, and aligns to couple with a respective one of the transmission line couplers to provide a contactless communication link between the transmitter and the elongated transmission line.

Abstract: An apparatus is provided. Transmission line cells are formed in a first region. A first metallization layer is formed over the transmission line cells within a portion of the first region. At least a portion of the first metallization layer is electrically coupled to the plurality of transmission line cells. A second metallization layer is formed over the first metallization layer with an interconnect portion, and overlay portion, and a first balun. The interconnect portion at least partially extends into the first region, and the overlay portion is within the first region. The first balun winding is electrically coupled to the overlay portion and partially extends into a second region. The first region partially surrounds the second region. A third metallization layer is formed over the second metallization layer having a second balun winding within the second region, where the second winding is generally coaxial with the first balun winding.
