## Abstract A low cost miniaturized CP antenna is proposed for UHF RFID (Radio Frequency Identification) reader applications. The antenna is composed of a vertical ground and a squareโring patch with truncated corners. A novel capacitively coupled feed structure is proposed for good impedance match
## Abstract A circularly polarized (CP) stacked antenna for the long range reader of a RFID is studied. The proposed CP antenna using stacked patch technique with a highโimpedance ground plane exhibits fairly good performances of 30 MHz bandwidth for 3 dB axial ratio, 70 MHz bandwidth referred to 1
## Abstract A UHF band nearโfield antenna using microstrip lines and stubs for tagging stacked tags in a smart table is presented. It is shown that a suitable nearโfield reader antenna can be designed from signal lines, ground lines, and several stubs to generate coupled electric and magnetic field
## Abstract This article presents a new UHF RFID reader antenna for a handheld reader system. An apertureโcoupled structure is employed to cover the North American UHF RFID frequency band: 902โ928 MHz. A thick highโdielectric substrate with a relative permittivity of ฮต~r~ = 8 is used for the size r
