Try this configuration if resonance is too high. 

Matching circuit generated from s-parameters by Optenni, using 2 components from Murata LQW15AN- and GJM15 series components. 

R3 on eval baord =  Inductor L1 

R2 on eval baord = Capacitor C1 

Increase capacitor C1 value to move resonance **downward**
