Hello JiWei,

if you want to use multilple antenna, you can use 50-OHM single-end antenna. the solution like this:

---PN532---Antenna Switch( <100MHz, and suitable for 13.56MHz, 50OHM)------->Multiple Single-end antenna.

and you can use HOST(MCU or procoessor) to control how to switch channel.

In addition, you can also use MOSFET to be switch.

Have a nice day!
