Q1:

The main difference between the broadside arrays and end fire arrays is that

A individual elements are fed with same current in broadside arrays and of different magnitude in end fire arrays

B in broadside arrays the elements are equidistant whereas in end fire array the distance between elements increases progressively

C the total number of elements in broadside array is always one and a half times that of elements in end fire arrays

D in broadside array the individual elements are fed in, out of phase by 180° whereas in end fire array individual elements are fed with currents of equal magnitude but their phases vary progressively along the line in such a way as to make the entire arrangement substantially unidirectional

ANS:D - in broadside array the individual elements are fed in, out of phase by 180° whereas in end fire array individual elements are fed with currents of equal magnitude but their phases vary progressively along the line in such a way as to make the entire arrangement substantially unidirectional
