1mm capacitor space inside a microstrip line

Topsy · Jul 24, 2013

please i need to create a 1mm space inside a microstrip line in the AWR environment, This space is needed for the capacitor.

I need this space to come out in the pcb without me cutting the 1mm space on the pcb. Any help on how to go about it in the layout

If you do this cut, the characteristic impedance and the characteristic transfer function of the microstrip transmission line it will change.
DGS - Defected Ground Structure topologies (for making microstrip filters) are based on cutting or adding slots into a microstrip line.

1mm space is huge, if you just need a capacitor, maybe 0.2mm or less is more viable. You need simulate it on your working band.
