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. © 2006 Wiley Periodicals, Inc.
