Abstract :
A broad band uniplanar antenna for passive UHF RFID tag applications is presented. The antenna has been designed to provide a multistandard transponder in one ISO 7810 ID-1 card with both the UHF meandered antenna and an ISO 15693 tag arranged in two separate sections. The broadband antenna is composed by a meander dipole and a loading bar electrically connected to it. It is found that the presence of the connected bar allows to obtain a reduced size meander antenna with both a satisfactory return loss and useful tuning characteristics. Finally, the simulated radiation pattern is in good agreement with that of a typical planar dipole antenna.
