I am having proble while doing impedance matching on L-network. As my circuit indicated below, my result on S11 is not the same as in the 2nd picture, which is not as pointy as mine. Can you suggest which parameters should I chan
ge to get the result like in the 2nd picture, all of the values of L,C and the microstrip line I derive from microstrip line calculator.

It is not possible to interpret what the simulation step size that you are using is (which would determine the number of frequency points) but it needs to be changed. A good starting point would be 101 points (Step-size of 30 MHz for 1GHz to 4GHz sweep) would give a smoother response.
 
Thank you, somehow the curve is perfectly matched.
