Claim Text:
1. A coupler for coupling a first and a second section of a transmission line embedded in a first and a second component respectively, comprising: a first half-coupler comprising a first non-magnetic, electrically conductive housing adapted to be mounted at an end of the first component, a first electrically conductive structure, and a first structure of dielectric material; and a second half-coupler comprising a second non-magnetic, electrically conductive housing adapted to be mounted at an end of the second component, a second electrically conductive structure, and a second structure of dielectric material, wherein the first section of the transmission line is electrically connected to the first conductive structure, the second section of the transmission line is electrically connected to the second conductive structure, and when the first and second components are connected end-to-end, the first and second housings come into contact to form together an electromagnetic cavity, inside which the first and second conductive structures are separated from each other by the first and second dielectric structures, so as to allow the first and second conductive structures to be in electromagnetic communication with each other, wherein the transmission line comprises at least one coaxial cable, each coaxial cable comprising at least one inner conductor and an outer conductor, and the outer conductor of each coaxial cable is connected to the first and second housings, and wherein each of the first and second conductive structures comprises a full ring made of an electrically conductive material, and each full ring comprises a connection point connected to one of the inner conductor(s), and a short circuit point diametrically opposed to the connection point and connected to the respective housing.
