1. Individual elements are fed with same current in broad side arrays and of different magnitude in end fire arrays
2. In broad side arrays, the elements are equidistant whereas in end fire array the distance between elements increases
3. The total number of total elements in broad side array is always one and a half times that of elements in end fire arrays
4. In broad side array the individual elements are fed in, out of phase by 1800 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.
