Sažetak
The recently introduced concept of waveguide miniaturization using uniaxial negative permeability metamaterial is extended to the design of an miniaturized open-ended radiator. The reflection coefficient and radiation pattern of such an antenna are investigated numerically and experimentally. The experimental prototype comprises an open-ended evanescent waveguide with a cross-section of 0.2l x 0.2l. The waveguide was filled with negative permeability uniaxial meta-material based on double-ring resonators in 7 GHz band and excited with specially designed probe. The measurements revealed H-plane radiation pattern with 3 dB beamwidth of approximately 100 degrees and return loss of 13 dB across operating bandwidth of 5%.
