zigzag antenna

hello everyone

i need to design zig zag antenna using cst
the problem i don't know how to draw the wired zig zag
i already try to design but using the curve polygon
so hope anyone can give idea to me.....

tq

I have not seen the picture of zig zag but u can do like this. IN cst menu Use
Curves->new cureve
Cureves->line

U can draw differnt line and connect according to your requirement

how to setting the angle if we use line?

Thanks,

kyg

ITs simple just define an angle and use polar coordiante while defining the line and use the angle there

thanks for help me i'am new for cst

tq

:D

hi snkhan,

the zig zag antenna that i design need to change into patch antenna in cst
so from the picture above how to implement that design to put the waveguide port

beside that, if the zig zag too sharp what the effect to the antenna?

tq.

Just make a simple patch antenna. While defining zig zag atenna.Just change the UV-cordinate (local coordinte CST) to xy-plane (the plane which contains ZZ-patch).To feed its simple to connect the Feed to pach.

this pic i already design but have problem will do the simulation
the problem at the waveguide port

the substrate use fr-4 material
the zig zag antenna use copper
and i do extrude at the substrate to get ground plane

Here i cannot see th port. U can also upload your model
