Testbed module for UHF passive RFID tags

The development of antennas for RFID tags requires measurement of the parameters; as well as, the response of these to be questioned by a reader, the variation of the parameters with simulation tools and building prototypes of antennas can be evaluated, compared, and verified to determine whether the label complies with the basic requirements. To do this, it requires a methodology to help determine the proper functioning, so that feasible to establish a reliable and fully operational RFID tag. Complying with the characteristics that are intended in the design of antennas for RFID tags high performance.
