Which consequence results when a phased array antenna's elements degrade unequally?

A)Beam pattern distortions manifest
B)Total radiated power rises
C)Operating bandwidth broadens
D)Input impedance uniformly decreases

💡 Explanation

Unequal element degradation causes beam pattern distortions because amplitude and phase relationships shift unevenly across the array from mutual coupling changes; therefore, beam focusing accuracy degrades, rather than exhibiting predictable changes of total power or bandwidth.
