PN7150 Impedance Match to what value?

We are using the PN7150 NFC module in our project. I have 5V connected to the VBAT pin and would like to know the Impedance matching value for maximum range. I have seen in application notes that sometimes its matched to 30ohm and sometimes 50ohm. 

How do I choose the impedance value?
