Foam Radiator

Traditional antennas, particularly in applications like ultrawideband array systems and space-based facilities, are known for their size, weight, and limited versatility. As these applications see a surge in demand, antennas are expected to be compact, lightweight, and adaptable in order to meet the evolving requisites. Therefore, there is an urgent need to reinvent antenna design and fabrication. Current antennas struggle to meet the requisites of compactness without impeding performance. The traditional approach usually involves bulky materials, resulting in heavy antennas that pose logistic and operational challenges, particularly in airborne or spaceborne systems. The lack of versatility in mounting options further restricts their usability across a variety of scenarios, underscoring the need for a lighter, more flexible solution.

Technology Description

This technology presents a unique way of crafting a lightweight antenna by using foam material that is strategically coated with a machinable material and later plated with metal. This method enables an effective radiator with dimensions and performance equivalent to traditional notch antennas but with significantly less weight. Mountable on a variety of substrates, embodiments of the technology can utilize mixed or multilayered foam substrates, including conventional printed circuit boards (PCBs), PCBs with sleeved coaxial vias, or foam substrates. What sets this technology apart is its response to the need for lightweight, versatile antennas, particularly in ultrawideband array systems and space-based applications. The incorporation of foam and metal-plated materials offers less weight without compromising performance, making it an ideal solution for applications for which weight comes at a premium. The invention's ability to be mounted on an array of substrates further enhances its flexibility and potential for widespread utilization.
