Transmission Line, Transmission Cable, Transmission Line Preparation Method, and Electronic Device

A transmission cable, comprising:

• a first transmission line;
• a second transmission line connected to the first transmission line;
• and
• a third transmission line connected to the first transmission line, wherein each of the first transmission line, the second transmission line, and the third transmission line comprises:
• an outer housing, comprising:
• a first housing comprising a first groove, wherein the first groove comprises a first inner wall;
• and
• a second housing fastened to the first housing and comprising a second groove, wherein the first groove and the second groove are enclosed to form a path, and wherein the second groove comprises a second inner wall;
• an outer conductor, comprising:
• a first conducting layer disposed on the first inner wall;
• and
• a second conducting layer disposed on the second inner wall;
• a support plate suspended in the path and comprising:
• a plate surface;
• and
• an edge fastened between the first housing and the second housing;
• and
• an inner conductor disposed on the plate surface.

An electronic device, comprising:

• a substrate;
• a first electrical component disposed on the substrate;
• a second electrical component disposed on the substrate;
• and
• a transmission line comprising:
• an outer housing, comprising:
• a first housing comprising a first groove, wherein the first groove comprises a first inner wall;
• and
• a second housing fastened to the first housing and comprising a second groove, wherein the first groove and the second groove are enclosed to form a path, and wherein the second groove comprises a second inner wall;
• an outer conductor, comprising:
• a first conducting layer disposed on the first inner wall;
• and
• a second conducting layer disposed on the second inner wall;
• a support plate suspended in the path and comprising:
• a plate surface;
• and
• an edge fastened between the first housing and the second housing;
• and
• an inner conductor, disposed on at least one plate surface of the support plate.

A method, comprising:

• preparing a first groove on a first surface of a first housing;
• disposing a first conducting layer on a first inner wall of the first groove;
• disposing an inner conductor on at least one plate surface of a support plate;
• fastening the support plate to an opening of the first groove;
• preparing a second groove on a second surface of a second housing;
• disposing a second conducting layer on a second inner wall of the second groove;
• and
• fastening the first groove and the second groove together.
