ABSTRACT:
A transmission line structure comprises a dielectric substrate (11) having first and second opposing sides separated by a first distance (3). A transmission line (13) is disposed on the first side while an opposed conductor (12) is disposed on the second side. The transmission line (13) has a first edge (4) a second edge (6), and a midde portion (8). Thicknesswise, the middle portion (8) is separated from the opposed conductor by the first distance (3), and at least a portion of the first edge (4) is separated from the opposed conductor by a second distance less than the first distance (3).
