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...

125KHz RFID Reader for Raspberry Pi from CognIoT on Tindie
125KHz RFID Reader from CognIoT. The Reader offers one of the best OOB (out of box) experiences for Pi based RFID readers. By using the UART of the Pi for communication and the built in intelligence of the Reader the user is able to operate the Reader without the need for libraries to be downloaded and compiled onto the Pi. Example software shows how to setup the 125KHz RFID Reader and how to monitor the RFID tags. The uses are endless - what will you design with the 125KHz RFID Reader?
The RFID reader is intelligent making your life simpler. The Pi sends commands to the reader over the...
Designing an RFID antenna - Hackster.io
Designing an RFID antenna:
Basically I am motivated to replace the antenna on this RFID reader. The reader is really cheap, and fits my porpoise, its recognized as a USB keyboard.
My Idea is to build a new antenna that can be fitted into a PVC tube and have a usb "reading rod". Basically I want to make a new coil with copper cable which area is a rectangle instead of a square.
Hackaday has provided me with some information about this, but nothing useful about antenna modding.

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.

at 125 khz, you will not have a real antenna, the size would be prohibitive. the best you can hope for is an inductive pickup. a coil on a ferite bar would work fine. check amidon associates for ferite antenna material.

How to boost a 125KHz RFID signal? - Forum for Electronics
I have a situation where I am using a RFID module to read a 125KHz tag, but the signal is very weak, so I would like to boost it. But, I am not sure how to do that. The antenna connects to the module (two pins) but since the signal is bi-directional (i.e. the 125KHz driving signal and the tag response signal) I don't think a simple amplifier will do the job. How to address this issue? Thanks!
