Yagi Simulation

Dear Friends,
I'm trying to simulate 3- element Yagi Antenna with hfss. I'm using folded dipole as the driver element (input imp 200Ω). for that i'm facing two problems

1. how shall i define excitation at the gap of folded dipole ? or is it better to use balun and simulate?
2. reflector and driver should be connected with boom?
please reply
thanks

Im also facing some problems using HFSS to simulate yagi antenna. Im not sure about the boundary conditions and the excitation part. Can anyone help?

u can use lumped port
draw a rectangle between ports and right click it and define the lumped port excitation
