Planar array design using CST ....

hello everyone ...

l'm doing a design for a planar array for a smart antenna ... l'm using CST program for my design and l need to do a comparison for the function of the antenna when a 2*2, 4*4, 8*8 and 10*10 elements of the planar array are used ...

so, shall l use a coaxial port to feed each element or l should use the transmission line techniques to feed them all with a single normal port ...

actually, l'm looking for the way which is gana give me the better and compatible design for my application ...

so l need ur experience to help me in this ... :)

thanks ...;)

For antenna radiation patterns and efficiencies, you can use EM-Core to simulate them.
