ABSTRACT:
A transmission line circuit is described which includes a conductive plane, a plurality of signal traces, and an intermediate layer between the conductive plane and the signal traces. The intermediate layer maintains a substantially constant separation between the conductive plane and the signal traces. At least a portion of the intermediate layer comprises air. The signal traces and the conductive plane form transmission lines.
