摘要：
A UHF band near-field antenna using microstrip lines and stubs for tagging stacked tags in a smart table is presented. It is shown that a suitable near-field reader antenna can be designed from signal lines, ground lines, and several stubs to generate coupled electric and magnetic fields. The proposed near-field reader antenna satisfactorily operates in a UHF radio frequency identification (RFID) smart table, and the measurements show that the antenna is capable of detecting 200 stacked tags in a reading area of 200 mm x 190 mm and achieves a detection rate of 97% when the tags are stacked in a smart table. The proposed UHF RFID smart table is successfully implemented for casino chip management. (C) 2010 Wiley Periodicals, Inc.
