A slot array antenna including a smooth curved surface and planar feed structures which are respectively disposed at two ends of the smooth curved surface and are tangent to the smooth curved surface. The smooth curved surface includes at least two arcs mutually connected by smooth transition. The at least two arcs each includes an upper copper metal layer, a lower copper metal layer, and a dielectric substrate layer between the upper and lower copper metal layers. The upper copper metal layer includes radiating slots, and the adjacent radiating slots in a linear array have opposite offsets along the center line of the slot array antenna. The dielectric substrate layer includes metallic vias symmetrically arranged on both sides of the central line of the antenna to form a substrate integrated waveguide.

Curved near-field-focused slot array antennas

A shared-aperture antenna includes a first copper metal layer; a second copper metal layer; and a dielectric substrate layer sandwiched between the first copper metal layer and the second copper metal layer. The dielectric substrate layer includes a plurality of metallized vias. The first copper metal layer is in communication with the second copper metal layer via the plurality of metallized vias. The plurality of metallized vias includes first metallized vias forming an inner circular ring and second metallized vias forming an outer circular ring with respect to the center of the antenna. The first copper metal layer, the dielectric substrate layer, the second copper metal layer, and the first metallized vias form a substrate integrated waveguide (SIW) circular cavity slot antenna. The first copper metal layer, the dielectric substrate layer, the second copper metal layer, the first metallized vias and the second metallized vias form a coaxial cavity slot antenna.
