Log Periodic Dipole Array Antenna Example

Hi friends !

I want to do Log Periodic Dipole Array Antenna Example but i get the error in sigmaN function veriable when entering veriables.

tau:0.93 (entered)

sigma0: 0.7 (entered)

sigma1...sigma11: sigmaN=sigma(N-1)/tau ( ı did not do this function)

how ı enter this veriable ?

Thanks in advance !

What error did you get?

From your description it looks like you have not yet defined N, so you maybe be getting an error that N is not defined.

First, Thank you for reply @Peter Futter

you say that right. how i can define N ? I know if i define N, everything will be okey.

My veriable; tau=0.93 sigma0= 0.7

sigma1...sigma11: sigmaN= sigma(N-11)/tau Thanks in advance !

I am not sure if I am missing something, but in the same way as you defined the other variables you need to defined a variable N and give it a value.
