Size reduction in microstrip antennas using left-handed materials realized by complementary split-ring resonators in ground plane

Abstract

The present work focuses on using left-handed materials (LHMs) for size reduction of microstrip antennas. Section I discusses the choice and design of a suitable periodic structure to realize negative permittivity and/or permeability. The Complementary Split-Ring Resonator (CSRR) is easiest to implement. Section II discusses the design and construction of the antennas with CSRRs in the ground plane. Design, construction and measurement have been performed and validated with simulated results. In Section III, based on the simulated and measured results a design methodology is proposed.
