Offset quasi-twin lead antenna
View Patent ↗The quasi-twin lead line includes a dielectric substrate having a first side and an opposite side. A top conductor trace is integral with the first side of the dielectric substrate. The top conductor trace has a top conductor axis, a top conductor length, and a top conductor width, wherein the top conductor width is substantially uniform along the top conductor length. An opposite trace is integral with the opposite side of the dielectric substrate. The opposite trace has an opposite length and an opposite width substantially congruent to the top conductor length and the top conductor width. The opposite trace also has an opposite axis substantially parallel to the top conductor axis, wherein a plane containing both the top conductor axis and the opposite axis is oblique relative to the dielectric substrate.
