RF37S114: Reader antenna for RF37S114

Part Number: RF37S114

Hello,

I want to increase the read range of RF37S114.I was reading  https://www.ti.com/lit/ug/slou372a/slou372a.pdf?ts=1683352884045. My coil size is 10mm by 10mm.

I want to know if my coil inductance is fixed at 0.95uH, whether I can improve the Q value by changing the Rpar value and choosing the appropriate parallel and series capacitor values?

Can the reading range of RF37S114 be increased by increasing the Q value in the case of appeal? 

I've read about www.ti.com/.../scba035a.pdf This pdf, but I would like to know how to improve the read range of RF37S114 when the coil inductance is fixed.

Because I increased the Rpar, I chose the capacitor accordingly, but the read range was shorter
