ANTENNA SYSTEM FOR WIDE ANGLE SCANNING ANTENNA ARRAY

Abstract: the invention relates to an antenna element comprising a dielectric substrate and a multi-layer laminate structure included in the dielectric substrate. the multi-layer laminate structure comprises an impedance matching layer, a resonating cavity with a cross-shaped slot, and a pair conductive forks, configured and arranged to feed the cross-shaped slot. the invention further relates to an antenna subarray, comprising a dielectric substrate and a multi-layer laminate structure included in the dielectric substrate. the multi-layer laminate structure comprises an impedance matching layer, an array of resonating cavities, each with a cross-shaped slot, and an array of pairs of conductive forks, each pair configured and arranged to feed the cross-shaped slot of a corresponding resonating cavity.
