IC Chip - Antenna/Inductor - Power Source

In this this antenna type - the RF waves emanate in a linear pattern from the antenna. Waves have only one energy field

A mechanical device for controlling or moving objects - A programmable logic controller (PLC) - robot arm - mechanical arm - etc.

Readability of a tag greatly depends on this and the angle at which the tag is presented to the reader

The orientation of the transmitted electromagnetic field or the direction of oscillation of electromagnetically emitted waves

Image "burned" into photopolymer layer. All copper removed except where image was burned. Copper antenna goes through additional processes to protect from oxidation

Divides time into discrete time intervals (slots) . A packet can only be transmitted at the beginning of a slot - reduces the collision duration.

When two waves (in phase) impose on each other and enhance the original signal and give rise to protrusions

Frequencies between 30-300 KHz - Generally use passive tags - have low data-transfer rates from the tag to the reader - and are especially good if the operating environment contains metals - liquids - dirt - snow - or mud. Active tags also available

Reader that can operate in different frequencies or can use different tag-to-reader communication protocols (generally stationary)

RF energy radiates from antenna in linear fashion - Provide longest range - Sensitive to the orientation of tag - Has single E-field component - Can have a narrow beam pattern - Best for application with known tag orientation
