Abstract :
A new method of directivity calculations for rectangular arrays composed of subarrays is proposed. The method is based on representation of a double integral on angular coordinates in the form of series of squared Bessel functions. As a result of application of the developed technique, an empirical formula for calculation of aperture efficiency for the beams of a multibeam array is obtained.
