I followed a tutorial of how to simulate a patch antenna on youtube.
When I tried to copy the procedure for a 2.4GHz patch antenna design I noticed the
impedance vs frequency graph looks a lot different from the tutorial one.
Also it is a lot smaller.
Your simulation volume has side walls. To allow radiation, these are simulated as absorbers (PML = perfectly matched layer). The distance to the antenna matters. Your tutorial should have details on that.

No, unfortunately it didn't.. So what you are saying is that the radiation box is too close to the antenna? Is there any guidelines to how far from the sides it should be?
Good mm.. maybe you can prove with lumped port for feed the patch, draw a rectangle between the microstrip line and ground and assign lumped port. For the radiation box is better use region (Draw-> Region) select absolute distance (31.25mm for 2.4GHz) then assign boundary radiation.
