Abstract :
In this paper the radiation pattern of the finite phased array of plane waveguides with an impedance flange has been theoretically investigated. The array radiation has been considered as superposition of radiation of each waveguide. Mutual coupling between waveguide apertures has been taken into account using variational principle in the single-mode approximation. Some numerical results for the array of eleven and fourty waveguides have been presented.
