A problem of a 1D-periodic (linear) array of flanged rectangular waveguides has been presented and discussed. The problem is reduced to a system of integral-algebraic equations where reflection coefficients and electric field are used as unknowns. The integral parts are algebraized using the piecewise constant approximation. The system obtained has been solved numerically. Dependence of the element gain in broadside direction on the square waveguide dimension has been obtained. The array performance at different scanning angles has been studied. Polarization characteristics of a square waveguide in array have been investigated.
