dear,
i have create my dual band design using HFSS v12.1. i've stuck because my design give a bad result. i think i've created a wrong design. please evaluate my design.
thanks all.
hi ferdows,
i've read books you give but still i can't find theoritical about design the coil for dual band. does it has a calculation or we can make it by our own way and not depend with any requirement such as diameter coil and how much turn we give?
and also the site you provide, i think the...

thanks
