Transmission line for radiofrequency range current

An electronic device comprising:

• a first conductive element and a second conductive element separated by a non-conductive volume;
• a first antenna and a second antenna configured at least partially within the non-conductive volume and/or the second conductive element;
• a first transmission line connecting the first conductive element to the first antenna across the non-conductive volume;
• and
• a second transmission line connecting the first conductive element to the second antenna across the non-conductive volume, wherein the second transmission line comprises:
• a signal current line;
• and
• at least one return current line;
• wherein the signal current line and the return current line(s) extend in parallel;
• wherein each of the signal current line and the return current line(s) comprises at least one first segment and at least one second segment, wherein each first segment is partially aligned with at least one adjacent second segment;
• wherein a respective first segment and a respective second segment are separated by a first dielectric gap and form a capacitive coupling across the first dielectric gap.
