Abstract:
A phased antenna array comprises a plurality of antennas and photodiodes arranged on a substrate. Each antenna is driven by an electrical signal output by the photodiode. The photodiodes each receive an optical signal via an optical fiber. The optical fibers conform to the sheet-like shape of the antenna array (which may be planar or curved) and optically communicate with a corresponding photodiode via a corresponding reflector, such as a ninety degree reflector. The reflectors may comprise a v-groove in a silicon substrate on which the optical fiber is positioned and a reflecting surface. Each reflector may be attached to the substrate or a ground plane positioned parallel to the substrate and the optical fiber may connect to the reflector in a direction running parallel to the phased antenna array. This optical feed network may accommodate tight spacing of the antenna elements (such as spacing less than 5 mm apart) with a thin profile.

Claim (Index 1):
A phased antenna array comprising:\n an antenna array substrate and a conductive ground plane spaced apart from the antenna array substrate at a substantially constant distance and having a shape conforming to the shape of the antenna array substrate, the antenna array substrate having an inner surface and an outer surface opposite the inner surface, the conductive ground plane having an inner surface and an outer surface opposite the inner surface, where the inner surface of the antenna array substrate and the inner surface of the ground plane face each other; a plurality of antennas arranged on the outer surface of the substrate; a plurality of photodiodes arranged on the inner surface of the substrate, each of the photodiodes having an electrical connection through the substrate to a corresponding antenna to drive the corresponding antenna; a plurality of reflectors, each positioned to be in optical communication with a corresponding one of the photodiodes; and a plurality of optical waveguides extending in a direction conforming to at least one of the inner surfaces or outer surfaces of the antenna array substrate and the ground plane, each of the optical fibers connected to a corresponding reflector to provide a optical signal to a corresponding one of the photodiodes via the corresponding reflector.
