ABSTRACT:
A non-uniform transmission line, including at least a first section with length L1, uniform width W1and thickness h1, and a second section with length L2, uniform width W2and thickness h2, joined together to form a composite structure and arranged in any of at least three distinct configurations. The composite structure (first section plus second section) may be periodic or non-periodic. Length and/or width and/or thickness of each of the two sections may be varied to provide desired values for characteristic impedance, cutoff frequency and/or time delay for signal propagation.
