125KHz RFID reader anntena coil - Forum for Electronics

i need some help pls... i currently modified a 125KHz RFID reader anntena coil, the actual read range for 125KHz RFID reader is about 4cm. I plan to remove the original anntena coil and replace with another anntena coil to improve the reading range. so, what type of material i needed to build the antenna coil? for example copper? is that correct? how many turn for the anntena coil? how many...

Interfacing RFID with Arduino - How to Read RFID Cards

In this tutorial, we are dealing with yet another interfacing technique. This time we are interfacing an RFID Reader which can read RFID Tags to Arduino. RFID is Radio Frequency Identification. An RFID reader is used to read RFID tags (which contain certain unique data stored in a chip). An RFID reader and an RFID tag, both have a coil surrounding them.  When an RFID tag is shown near an RFID...

Types of RFID Tags

 

RFID Tags come in three basic varieties: passive, active, or semi-passive or battery-assisted. RFID Tags and Readers are available in a range of different frequencies with 125kHz, 13.56MHz, 868MHz and 915MHz being the most common frequencies.

Passive RFID Tags:  A Passive RF Tag requires no internal power source and generates no RF signals itself. Passive RF Tags are powered by readers when they are in range. They inherit...

RFID Circuit & PCB Design Notes

It's usually very important that the voltage supply to an RFID reader is protected from ripple and interference.

Where you have noisy electronics in the proximity:

A simple RC filter of 10R and 1000uF will go a long way to preventing interference. Better still is using a separate power supply from a dedicated voltage regulator if you have the option.
