RFID (Radio-Frequency Identification) Definition

Stands for "Radio-Frequency Identification." RFID is a system used to track objects, people, or animals using tags that respond to radio waves. RFID tags are integrated circuits that include a small antenna. The are typically small enough that they are not easily noticeable and therefore can be placed on many types of objects.

Like UPC labels, RFID tags are often used to uniquely identify the...

I'm going to examine the maths of transmitting power from a point source (the reader antenna) and assume the passive tag has an antenna that can pick-up, rectify and re-use a fraction of this power. This doesn't consider near-field effects/benefits (these may save the day but my gut feeling suggests they won't).

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...
