Scan Blindness in a patch antenna linear array

Scan Blindness

Hello people,

let´s consider a patch antenna linear array 12x1 in Linear polarization.
Every port is -10 dB matched and the mutual coupling is at -25 dB. (BW=200 MHz).

It´s a scanning array (from -45 to +45 degrees).

In my opinion the Scan blindness is a real problem.

What do u think?

Do u have a plot "reflections at every port vs scanning angle"?

Thanks in advance
