RFID Antenna Tutorial | RFID Antenna Types

The RFID reader antenna transmits a wave that has both electrical and magnetic properties and is known as an electromagnetic wave.

There are 3 different types of RFID antennas:

Linear Polarization (dipole antennas) - the electromagnetic wave propagates entirely in one plane (Vertical or Horizontal) in the direction of the signal propagation. This is the best wave propagation when the tag...

Active vs. Passive RFID

When do I need to use Active RFID? Or will Passive RFID work just as well?

Active RFID and Passive RFID are fundamentally different technologies that are often evaluated together. While both use radio frequency energy to communicate between a tag and a reader, the method of powering the tags is different. Active RFID uses an internal power source (battery) within the tag to continuously power the tag and its RF communication circuitry, whereas Passive RFID relies on RF energy...
