Antenna array Complex directional antenna consists of separate near-omnidirectional antennas (radiating elements) positioned in the space and driven by high-frequency … (from 'Glossary' of our website) |
All ArchivesPatch antennas with artificial dielectrics substratesApproach for the analysis and Qfactor estimates of patch antennas with artificial dielectrics substrates for decimeter and larger wavelengths have been considered. Parameters range not leading to significant normal dispersion have been estimated and treated. Also shown that a frame of periodic system of capacitive elements aligned along the patch wedges provides smaller Q compared to the homogeneous dielectric substrate with the same equivalent permittivity. Implementation ...
