MILLIMETER WAVE ANTENNA STRUCTURES WITH AIR GAP LAYER OR CAVITY

摘要

Embodiments of millimeter wave antenna structures are generally described herein. The antenna structure may include an a radiating element layer comprising a patterned conductive material a ground layer comprising conductive material disposed on a dielectric substrate and a feed line layer comprising conductive material disposed on a dielectric substrate. In some embodiments the antenna structure may include an air gap layer disposed between the radiating element layer and the ground layer. The air gap layer may include spacing elements to separate the radiating element layer and the ground layer by a predetermined distance. In some other embodiments the radiating element layer may be disposed on a radiating element dielectric substrate which may include one or more cavities between the radiating element layer and the ground layer.
