Recommended ground mat antenna for M7E module

I’m using your M7E RFID module and I’d like to use it with a floor or ground mat antenna (the type placed on the ground, often used in race timing systems).

Could you please recommend which antenna model would be ideal for this purpose — compatible in frequency, connector type, and power with the M7E?
I’m looking for something reliable for reading tags worn on a runner’s shoe or ankle when they pass over the mat.

Thank you very much

I have no information to recommend an antenna like that, but I there was a post from someone who build a running trail solution. ( Simultaneous RFID with motion sensor - #5 by PBrad ) Maybe their solution can help you.
