I have simulated a linear antenna array in hfss.
the return loss plots for 1 into 2 array , 1 into 4 array, 1 into 8 , 1 into 16 and 1 into 32 array are not the same
the 2 elements array is resonant at 5.08 GHz, 4 elements array again at 5.08 GHz , 8 elements array at 5.2 GHz . 16 elements array at 5.6 GHz and 32 elements array at 6.2 GHz
this is resulting return loss even greater than -5 dB at 5 GHz
i want the response to be at 5 GHz,atleast -20 dB return loss at 5 GHz
the plot i am talking about has db S(1,1) on y axis and frequency on x axis
can somebody tell me that what could be the reason and solution for this?
