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...

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.
