Hi

akedar, u hv lot of points. u can easily download. U must log in to download.

Please refer to some antenna textbooks. They usually have a subsection about how to design them.

I also have some problems with balun, I don't know how to achieve it in HFSS with LTCC

Does anyone have simulation of balun on LTCC?
