ANTENNA ARRAY RADIATION SHIELDING

Abstract:

Systems and methods are described for supporting radiation shielding of an antenna array. For example, an antenna array in accordance with the present disclosure may include shielding elements that provide a degree of radiation shielding to other components of the antenna array, such as a substrate of the antenna array. In some examples, the shielding elements may be positioned to overlap with one or more gaps between antenna elements, or one or more gaps between ground elements (e.g., when viewed from a radiation source, when viewed in a direction perpendicular to a substrate). Thus, shielding elements of an antenna array in accordance with aspects of the present disclosure may reflect, absorb, or otherwise dissipate radiation that passes through such gaps before the radiation is incident on the other components of the antenna array, such as the substrate of the antenna array.
