Patent ID: 8907861

Claim:
An RF antenna apparatus, the antenna apparatus comprising: a construction component containing a first piece of dielectric construction material; an RF port attached to the construction component and electrically accessible from outside the construction component; and a plurality of radiating elements and a conducting sub-reflector embedded in a non-planar arrangement within the construction component, the plurality of radiating elements including a first radiating element and a second radiating element, the first radiating element a first depth from a surface of the construction component, the second radiating element a second depth from the surface of the construction component, one or more of the first radiating element and second radiating element having a flat surface, the flat surface oriented neither parallel to the surface of the construction component nor orthogonal to the surface of the construction component, the radiating elements electrically connected to the RF port and configured to radiate directly into the first piece of dielectric construction material before radiating into free space outside the construction component, the radiating elements supported by a portion of dielectric construction material located behind the radiating elements relative to the free space and between the radiating elements and the sub-reflector, wherein the dielectric construction material located behind the radiating elements relative to the free space and between the radiating elements and the sub-reflector is the same as the dielectric construction material contained in the construction component.
