PN532 Single Ended Antenna Design

[testbed]

Hello,

I am looking for references / application notes for connecting an antenna to the PN532 in single ended mode.

E.g. all the necessary calculations for the matching network / EMC filter etc.

I happend to find this on the forum, but it is for the CLRC663 frontend, so looking for something silimar for the PN532

Additionally looking for methods to connect multiple antennas to the PN532 using a mux. I know there is this app note - AN11314 Multiple Antennas on Single Reader IC - which describes the same but it has been removed from the NXP site...

Thank You

The document AN11314 is restricted. You can request it from the DocStore. (https://www.docstore.nxp.com).

Hi Jimmy,

I got access to the docstore and selected access to all NFC related docs. Yet, when i search the store using the app note number or relevant text, the search results turn up empty....

Maybe your "Access level" is not high enough.So you cannot see the document.

The AN11314 is under "NFC Frontend Solutions" -> "Application Notes".

In "My Access", there is "NFC Frontend Solutions". You can try to request the higher access rights there.
