Log Periodic Dipole Antenna

[Sri Harsha]

Hi Friends,

I am designing log periodic dipole antenna in ADS but i am not getting exact results over the wide band from 2GHz to 10GHz, Can anybody help me with designing values and images and i have one more doubt like whether is it possible to design LPDA in ADS why because normally an LPDA antenna doesn't need any substrate right so can anybody suggest me???

Thank you in advance,

I would recommend LPCAD. Its easy to use and will give exact calculated values.
