Investigation of characteristics of phased antenna array considering interaction between radiators and properties of power divider
Abstract
A method is proposed for investigating the characteristics of infinite block phased arrays in which the elements form a regular structure, with allowance made for a power divider, which provides arbitrary amplitude phase distribution within the block. The influence of nondissipative dividers as well as dividers incorporating absorbing elements, is investigated. An effective algorithm is constructed for analyzing the characteristics of block phased arrays designed for scanning within a limited angular sector, and of ordinary phased arrays with element by element phasing, with allowance for interaction of the radiators with respect to external space as well as through the power circuits. The numerical results indicate that the influence of the power divider must be taken into account when designing phase antenna arrays.
