Abstract:
The loop antenna includes a loop coil connected to an RF signal source of a reader through a feed cable, and a switch that is turned on and off depending on a DC voltage that is proportional to the magnitude of an RF signal supplied from the RF signal source of the reader and opens the loop coil when turned off and closes the loop coil when turned on.
Abstract:
A tag apparatus communicating with a reader acquires a command from a signal that is received from the reader, converts data corresponding to the acquired command to a plurality of multi-level parallel data, and generates a plurality of tag load impedances based on bias voltages that are mapped to correspond to each level of the plurality of parallel data. Therefore, a signal having electrical energy corresponding to the plurality of tag load impedances is transmitted to the reader.
