## Abstract A UHF band nearβfield antenna using microstrip lines and stubs for tagging stacked tags in a smart table is presented. It is shown that a suitable nearβfield reader antenna can be designed from signal lines, ground lines, and several stubs to generate coupled electric and magnetic field
## Abstract A microstripβbased segmented coupling reader antenna is proposed for nearβfield ultra high frequency radio frequency identification applications. The measured reading distance is 13.5 cm in the air and the measured bandwidth is around 55 MHz (895β950 MHz) under the condition of voltage
