Zusammenfassung:An antenna stack includes a glass cover having an outer face, an inside face opposite the outer face, and a body therebetween. The glass cover additionally has a cavity formed therein, extending into the body from the inside face. The antenna stack further includes an antenna patch positioned within the cavity, and a waveguide layer. The waveguide layer includes polycrystalline ceramic underlying the glass cover. Conductive vias extend through the polycrystalline ceramic and partition the waveguide layer to form feed channels through the polycrystalline ceramic, and major surfaces of the polycrystalline ceramic are overlaid with a conductor having openings that open to the feed channels. The antenna patch is spaced apart from the waveguide layer to facilitate evanescent wave coupling between the feed channels and the antenna patch.
