Abstract
We consider an advantage of using dielectric materials with different permittivity in the radome design to reduce far side field and to improve directivity properties of a two-dimensional antenna array in a radome. For calculations, the method based on solving the volume integral equation relatively the total field in the radome is used.

KEY WORDS: antenna radome, bore-sight errors, integral equation method
