Abstract

A two-dimensional (2D) periodic array of slot radiators excited by strip transmission lines is analyzed. A boundary value problem (which is then reduced to a system of integral equations for equivalent magnetic currents in the slots) is formulated. Expressions for the array scattering matrix and radiation parameters (radiation pattern and gain) are derived. An algorithm for numerical solution of the boundary value problem is developed. Various array operation modes are analyzed.
