ST25R3911B detect antenna is plugged/unplugged

Hello, 

We have an pluggable antenna connected to a ST25R3911B. We need to find an efficient way to detect when the antenna is plugged/unplugged. What is the best way to do that?

    Hi Javier,

    you measure amplitude and phase of the antenna and compare them against known good values. This among other diagnostics are also discussed here: debugging-st25r3911b-loss-of-sense-range.
