Which of the following is the main difference between waveguide and transmission line?
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
