how to extend rfid chip antenna Here are some things I've considered: Ditch the embedded antenna on the cheap RFID reader and construct my own, larger antenna. I'd need to see if the onboard MFRC522 is up to the task of providing additional power. Look for a different IC around which to build a reader . You can browse all the Animal Crossing series amiibo cards and amiibo figures, or use the filter to find specific characters. You can use My Collection to keep track of the amiibo you already own and My Wish List to make note of those .

A larger tag antenna would increase the read range only slightly. Of course, if you want a read range of longer than 3 feet, you should consider using passive ultrahigh-frequency (UHF) RFID. You only have to remove the soldermask from the antenna (near to C11 and C10), destoy the connection to the antenna (in back of the soldermask) and finally solder the new antenna on the place where you removed the soldermask.
There are various RFID protocols but all rely on a transmit period followed by a listen period. Boosting the output power with an amplifier into the antenna improves the chance of the tag responding but does nothing to improve the chances of hearing it respond.
Tldr: how can I add an external antenna to an existing nfc/rfid reader to extend its read-range? I got a cheap Amazon smart cabinet lock that works with just about any nfc tag/rfid tag i put in front of it, as long as I set that type of tag/chip as the control card. All RFID readers have the ability to control how much power they send through the cables to the antennas. Check your reader’s settings to see how much transmit power you are transmitting (in dB); the higher the number, the more you'll increase read range, and vice-versa.
If the antenna was much larger than the gap, the loss is linear with a gap, x. If the antenna is much smaller than the wavelength, the loss factor is x² (Friis Loss) There are many examples on Hitachi's website to extend the aperture size and boost the range of the chip. Long answer is going to depend on what part you want to increase range on like u/Cornz38 said, and how much work you want to put into it. For SubGHz, you'd have to tear it apart, yank out the antenna, solder in a socket.
boosting rfid signal
One way would be to boost the reader antenna’s power output. But most countries place limits on the amount of RF energy that devices can emit—for health reasons, and to prevent them from interfering with other devices. Another way would be to increase the tag antenna’s size. The report "How to Build a Low-Cost, Extended-Range RFID Skimmer" by Ilan Kirschenbaum and Avishai Wool explains how to build an NFC reader that is able to read NFC card from a 25cm distance using 40cm antenna. eprint.iacr.org/2006/054. – FaST4.
