how to define the substrate and ground heights for FR4 ?

hello there ...

l'm doing a design for a microstrip patch antenna using CST software ... so l should define the substrate thickness or height , the patch height as well as the ground height ... what l have is the 1.524 mm as an overall height ... so l got confused in how to specify those heights ...

l appreciate your help ... :)

regards ..

hai,

in CST go to help and type patch antenna. there u will get the complete description

I am also confused about 1.524 mm height...are you sure is not 1.523 mm?

i use 1.6mm for FR4 substrate and 0.035mm for ground height...
