It looks like NXP route half of the first loop before jumping into the second with a via and half of the second before jumping to the third by via the third loop is finished before returning to the second half of the second loop and then it return to the second half of the first loop Something like this photo. Its impedance matches the device internal tuning capacitance value.
Design hints on how to place the components on a PCB are not. Im a college student learning the basics of NFC loop antenna design. For a maximized rangepower transfer the NFC antenna should have similar shape and size to the antenna it is intended to work with.
The details of the antenna design should be checked in each IC application note as. This paper introduces a kind of double sided PCB loop antenna which is designed for small size NFC tag working in complex environment and proposes a solution to improve the quality factor of NFC tag. Ive seen single layer designs with a 0 ohm resistor as a jumper over the traces It cant be more than 10x10cm or 4x4in.

NFC inductive loop — matching network -. The NFC antenna does not need to be placed in the same layer as the chip. As a starting point Im trying to design a PCB-based rectangular NFC loop operating at 1356 MHz matched to 50Ω.
Document information Info Content Keywords NFC MFRC522 MFRC523 PN511 PN512 PN531 PN532 Antenna Design RF Design constant current design. Just reader antennas with pre-loaded parameters for most NXP IC offerings. It then depicts a measurement method in order to evaluate the performances of the antenna prior to connecting it to the NXP NFC chip.
NXP provides several online training sessions guidelines and application notes on antenna design and explains carefully which parameters to look for and how to get the best performance. A complete example is calculated to help start the antenna design. It must be single layer.
VOC is the open-circuit voltage of the loop antenna caused by a magnetic field Ra is the corresponding loop antenna resistance.

The antenna design process begins with the NFC chip approximate solution and its loop antenna. In addition to the antenna layout there are some best practices that are recommended to make the antenna tuning process much easier. The NFC Antenna Design tool supports the antenna coil synthesis based on some basic input parameters and calculates the matching circuit for the following NXP NFC Reader ICs.
PCBBUY Provides All Kinds of Custom PCB Based on Your Requests. Show activity on this post. A sandwich design with the NFC antenna placed above or below the chip will make the design a lot more compact but it has some disadvantages.
If placed below the chip. The design of an antenna for dynamic NFC tag is based on the placement of a loop on the application PCB. Easy antenna design with NFC Cockpit software and PCB adaptors for antenna matching Easy application development with full NFC Forum and EMVCo compliant contact and contactless libraries Smartcard reader and SAM slot extensions Features Orderable part number.
Antenna Design Guide for the TRF79xxA 23 Design Tips for PCB Antenna Design After the dimensions of the antenna are determined in most cases the next step is to lay out the PCB antenna. Basic NFC Loop Design on PCB. I need it to successfully transmit data between the PN512 and an external NFC device 5cm 2 in or less range will be more than fine.
The lower radius windings of the spiral are largely superfluous to the energy transmitted to the receiver and so if you had say four layers the optimum would be to put stacked turns on each of the four layers just like a regular. It has a simple GUI to make it very easy to start designing and simulating antennas and it works. Ad PCBBUY Faster Response times Better Understandings of your PCB Needs.
