A novel method for calculating radiation patters of phased array antennas with an icreased interelement spacing

A new technique for calculating the radiation patterns of linear equally spaced phased array antennas consisting of highly directional antenna elements with an increased interelement spacing is considered. The concept of point interpretation of the elements of a set of highly directional antennas turns out to be untenable, since the phase characteristic of each element in the far zone can be considered quasi-constant only in the angular limits of the width of the radiation pattern of the element.
