Research output: Patent


A transmission line (1) for transmitting radiofrequency range current between a first conductive element (2) and a second conductive element (3), the transmission line (1) comprising a signal current line (4) and at least one return current line (5), the signal current line (4) and the return current line(s) (5) extending in parallel. Each current line (4, 5) comprises at least one first segment (6) and at least one second segment (7). Each first segment (6) is partially aligned with at least one adjacent second segment (7), aligned segments being separated by a first dielectric gap (8), and each aligned first segment (6) and second segment (7) forming a capacitive coupling across the first dielectric gap (8). This solution enables a transmission line which provides only small capacitive loading onto its surroundings, and which therefore can extend, e.g., through an antenna element without significantly affecting the performance of the antenna element.
