DC Resistance of Inductors
\$R_{DC} = 1.1 \Omega\$ for a \$ 1.8 \mu H\$ Coilcraft 0603LS inductor (datasheet).

But the non-linear Q-factor, shows the effective resistance \$R_{Eff} = R_{DC} + R_{AC}\$ will have a more significant effect on your actual circuit.



Yours is not plotted, but peak is at ~8MHz for the \$ 1 \mu H\$ inductor.  Say Q = 23, which means \$X_{L} = 50.3\Omega\$.  \$R_{Eff} = 2.18 \Omega\$ as compared to stated \$R_{DC} = 0.81 \Omega\$.  

So you cannot just go by \$R_{DC}\$, which is constant.  Simulations prove the concept, but the actual circuit depends on actual components. 



The DC resistance is the resistance of the wire (constant).  It can be measured.  It is present in ac and DC circuits.

The ac resistance is due to eddy currents, hysteresis, radiation and skin effect.  It is frequency dependent.  The ac resistance does not exist in DC circuits (no frequency).

$$ Q = \frac {X_L} {R_{Eff}} = \frac {X_L} {R_{DC} + R_{ac}}$$

See Practical Inductor or search google for a better explanation.

You were focusing on getting an inductor with low \$R_{DC}\$, but what you want is an inductor with a high Q (Q-factor) at your operational frequencies.
