Solution Overview

Problem

Conventional patch antennas and radomes are often designed and manufactured independently, leading to increased costs in conformal installations and compatibility issues, as well as potential performance degradation due to material incompatibilities and separate integration challenges.

Innovation Solution

An integrated patch antenna and radome assembly is developed, where the antenna and radome are combined into a single unit using a dielectric substrate with a conductive coating and a moat structure, allowing for conformal installations without compromising antenna performance, and utilizing materials like FR4 and quartz or glass pre-impregnated fabric for the radome.

AI summary

According to one embodiment, an integrated patch antenna may comprise a radome layer, having an outside surface and an inside surface, and a radiating layer. The radiating layer has a top surface and a bottom surface, the top surface of the radiating layer conforming to the shape of the inside surface of the radome layer. The radiating layer comprises a dielectric layer, a radiating element formed on a first side of the dielectric layer, and a moat formed in the dielectric layer around its perimeter forming an inner perimeter sidewall and an outer perimeter sidewall. The radiating layer also comprises a conductive coating disposed on the inner perimeter sidewall or the outer perimeter sidewall and a feed line disposed on a second side of the dielectric substrate.
