Abstract
A coplanar left-handed material, symmetric square labyrinthine ring (SSLR), is proposed in this paper based on labyrinth structure. The effective permittivity and permeability of the SSLR structure are retrieved using NRW (Nicolson-Ross-Wire) method and approach zero at 5.8 GHz. Then the proposed structure is applied to an open-ended waveguide antenna, and simulation results indicate that the proposed SSLR structure can effectively improve the gain about 5.5 dBi. The far-field of a dual ridge horn antenna with and without SSLR structure is also measured. Results show that the gain of the antenna is enhanced about 3.2 dBi, and the back lobe is suppressed.
