CLRC663 Multi-antenna polling work with what switch IC appropriate, external PCB antenna matching need to pay attention to what? Thank
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!
