LDS Antenna Radiation Element Weight Reduction

The patent uses a composite structure combining plastic support frames with metal reinforcement ribs and metal reflection sheets. The plastic provides lightweight support while metal ribs provide localized structural strength where needed, and metal reflection sheets are used only where required for electromagnetic performance, not throughout the entire structure. This composite approach reduces overall weight while maintaining necessary structural strength.

The antenna array is divided into multiple independent antenna elements, each with its own support frame and reflection sheet. This segmentation allows each component to be optimized independently and facilitates modular assembly, reducing the need for excessive material in any single component while maintaining overall structural integrity through the modular design.

The patent replaces complex metal die-casting with simpler plastic injection molding for the support frames, combined with straightforward metal rib attachment and reflection sheet installation. This composite manufacturing approach uses simpler, more cost-effective processes while achieving the required structural strength through the combination of materials and modular assembly.

By dividing the antenna array into modular elements with standardized support frames and components, the patent enables simplified manufacturing through repetition and assembly rather than complex monolithic fabrication. Each module can be manufactured independently using simple processes, then assembled into the complete array.
