When should i use MicroStrip and when smd components for a frequency filter?

Thank you.
 

I think the answer much depends from the frequency you are working with. If you work below 1 GHz, microstrip components could be cumbersome and thus occupy a lot of room on the PCB.

The big advantage of microstrip, in my opinion, is that you can easily obtain non-standard inductance values, and this could be a real challenge in RF filters.
 

My central frequency is 36,15 MHZ and my wideband is of 8MHZ, so i think filter made of smd components would be better. Any suggestions?
 

If %5 of your wavelength exceeds the component size you can use Microstrip or other alternatives. Your operating frequency is not high you can use ceramic , smd components.
