Abstract
A subarray of a planar array antenna has a ground plane having a rear face and a front face, radiating elements, each of the radiating elements protruding forward of the front face and physically mounted to the ground plane; circuit elements electrically coupled to the radiating elements, and physically mounted to the ground plane and positioned rearward of the rear face of the ground plane; and a dielectric radome supported on the ground plane defining a continuous surface sealed to the ground plane. The continuous surface includes a forward wall positioned forward of each of the radiating elements to form an environmental seal around the radiating elements. The radome has an intermediate wall intermediate at least one pair of adjacent ones of the antenna elements.
