a. RFID Building Blocks:
Tags: A tag is the data carrier and normally contains the ID number, and unique EPC code programmed into the Tag
Tag Antenna: The tag antenna is connected to the chip in tag. It could be wire or printed using conductive ink.
Reader Antenna: It is a coil included in plastic or similar case, and normally measures 12 -18 inches square
Reader: A reader captures...

b. RFID Block Schematic:
A simplified block schematic of an RFID tag (also called transponder) is shown in the diagram below. Various components of the tag are as shown. Normally, the antenna is external to the tag chip, and large in size.
The operation of the RFID tag is described below:
Handshaking with the Reader (interrogator):
The reader continuously emits RF carrier signals, and keeps observing the received RF signals for data.
The presence of a tag (for our discussion, we consider only passive tag) modulates the rf field, and the same is detected by the reader.
The passive tag absorbs a small portion of the energy...
