When I plotted the dBm(RF_IN) I obtain -9 dBm right after the RF source which is set at 0 dBm (see images below) . I do not understand why I did not obtain 0 dBm in the plot.

Thank you for your answer. I tried using the P_Probe1 but I get 0.2691 mW instead of 1mW (0 dBm)."dBm" function assumes that the Voltage over the Impedance is 50 Ohm but your case is different.
If you know the Impedance when you look into the circuit, you have to use dBm(RF_IN,Impedance).
But there is simpler method. Use P_Probe element to measure the Power that gets into the circuit.
So there is a Mismatch between the Source and the Circuit.Thank you for your answer. I tried using the P_Probe1 but I get 0.2691 mW instead of 1mW (0 dBm).
Thank you for your answer. I have managed to increase the value to 0.9 mW by adding a microstrip line in series with an inductor in series with a resistor. Is this configuration valid since I have not based it on any available matching circuit configuration ( I just added them arbitrarily)?So there is a Mismatch between the Source and the Circuit.
Because 0 dBm is Available Power from the Source. Not Entered Power.
If you design a good matching circuit, this entered power will be same as Available Power.
