Abstract(in English) | Small radio tags in a ubiquitous communication system are now developing. Very small meander line antennas are thought promising for these radio tag antennas. Previously, many important studies such as structural conditions and improvements of gains by folded structures were made. However, their sizes were beyond o.1 wavelength. In this paper, antennas less than 0.1 wavelength are developed. In this case, ohmic resistances of antennas affect strongly on antenna efficiencies. First of all, step up ratios for radiation resistances and ohmic resistances are measured in 0.1 wavelength and 0.05 wavelength antennas. As results, antenna efficiencies, radiation and ohmic resistances and step up ratios are ensured. |
