Abstract

A novel via-free microstrip Left Handed (LH) Transmission Line (TL) utilizing Radial Stubs (RS) is proposed. The microstrip RS is approximated by a series combination of inductance and capacitance. The electrical equivalent circuit of LH TL unit cell including the equivalent inductance and capacitance of radial stub is discussed. The balanced and unbalanced LH TL is implemented in microstrip technology and backward waves are confirmed by both full wave simulations and experiments. Additionally an open-circuited Zeroth Order Resonators (ZOR) with their resonating properties in balanced and unbalanced left handed transmission lines are also verified by full wave simulations and experiments.
