<P>PROBLEM TO BE SOLVED: To provide an antenna suitable for a radio frequency identification (RFID) tag. <P>SOLUTION: An antenna can be provided by a patch cell 210a (a patch cell array comprising two or more patch cells) or by a patch cell stack comprising two or more patch cells. An equivalent circuit for the patch cell 210a can comprise at least two inductances 242a, 244a and a shunt capacitance 246a. An equivalent circuit for the patch cell array can comprise two or more inductance groups connected via a series capacitance and two or more shunt capacitances. An equivalent circuit for the patch cell stack can comprises two or more capacitances connected via a series inductance and two or more shunt inductances. The antenna can have a composite right- and left-handed (CRLH) structure. <P>COPYRIGHT: (C)2012,JPO&INPIT |
