Replace Lumped Circuit Design by microstrip in ADS

I don't know to replace Lumped Circuit by Microtrip in ADS. It is dificult because I don't know fomula to caculate.
Example capacitor (C= 1.728 Pf) is replaced by MBSTUB W=40 mil anh angle 60
L=3.129 nf is replaced by Mlin W=115 mil and l =300 mil
You show me to design it. (book or software or caculated)
thanks!!!

you can take a look at any microwave book, specifically at filters section. I recommend Microwave Engineering by Pozar. In the filters section it should explain how capacitors and inductors are realized by microstrip lines.

Notice that small segments of open-ended or short-ended microstrip line segments (stubs) act as inductors or capacitors...

Thanks Zottiri Kusuta
I design with frequency in range (88-108 MHz).So, microstrip such as L,C is big ???.

It is natural that at lower frequency LC realization is impractical and use discrete one

You can take a simple RLC circuit and compare it with a microstrip circuit using tune tool available in a an circuit simulator....
