Hi Kevin,
S22 should be closer to S11, whether it be 50 ohms or at some other common value -- or your simulated open-loop gain results will be inaccurate. And you must also plot your phase, which must be at or near zero degrees at your peak S21 gain. And for maximum loaded Q -- and it looks like you are already doing this -- keep 'c' (the series inductor) high in value, and 'd' (the series capacitor) low in value (the narrower the S21 slope the higher the Q). And your biasing resistor 'h' is too low in value (unless you have a high current or low Vcc oscillator); but if you have calculated that that is the bias you want, then you will have to add a choke (an RFC) in series with the resistor, as well as a decoupling cap between the battery and the RFC, to stop the RF from entering the supply.
Best,
Bill
