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...

Get distance from an RFID Tag [solved] - Arduino Forum

Aug 23, 2016, 10:21 pm Last Edit: Aug 29, 2016, 01:25 pm by Meric

Dear Arduino community,

Hi there,

I've got an IR+RFID guided robot. I have to target many objects in a room, one after the other. All are in a random position. Each one is RFID passive-tagged.

I proceed like that: I target an object with the IR, I reach it, and I check if the target is the right one with an RFID validation.

Now, I would like to validate the objective before to totally reach it �

A way for that is to roughly compare the IR measured distance and the RFID measured distance, and to conclude if the target where we are going is the right one. I even think that compare...

Abstract

Objective

The location services has been an important research area in the U-Healthcare. The location services in medical environment can be implemented by Radio Frequency Identification (RFID), and Received Signal Strength Indication (RSSI) which is the location tracking method by RFID. In this study, we was designed the Patient Location Monitoring System based on RFID using RSSI method.

Methods

The RSSI method is a distance measurement method from reference points to object using the Friis's Principle and the...

Abstract--The efficiency of cold supply chain operations can

temperature threshold sensor that is capable of relating the

violation of a temperature threshold to a shift in the optimal

operating frequency at which the tag antenna is well matched

to the tag IC. This shift...

RFID gates – The technology behind them - RFID Arena

An RFID gate is a physical gate with a fixed RFID reader and antenna(s) attached to it. The system registers everything that moves through the gate as long as it is equipped with an UHF RFID tag. RFID gates use the same technology as RFID mobile computers, except for that everything works automatically and no manual labor is required. The automated operations make RFID gates a faster and more...
