Characteristics of a rectangular waveguide array with a frequency-selective shield of semielliptical shape with expansion of an operating band are investigated. It is shown that the region of transparency of the shield displaces down in a frequency in a comparison with the plane infinite frequency-selective surface (FSS). In this region the shield slightly changes the form of the main lobe of radiation pattern of an antenna array and increases far-out side lobes. Out of this region the shield reduces a backward specular scattering from an antenna, but increases a bistatic scattering.
