Basic Radiation Properties of Waveguides Filled With Uniaxial Single-Negative Metamaterials

Basic radiation properties of miniaturized open-ended waveguide radiators based on anisotropic, either mu-negative (MNG) or epsilon-negative (ENG) fillings have been investigated experimentally. It was found that a resonant MNG filling offers a high degree of antenna miniaturization with narrowband operation and pronounced losses, a wire-based ENG filling offers low degree of miniaturization with very low losses while the ENG filling based on inductively loaded wires offers both high degree of miniaturization and low-loss operation.
