Stamped Antenna Vibrator Structure for Cross-Polarization Isolation

The radiation board is divided into multiple functional regions: a feeding region for signal input, a radiation region for electromagnetic wave emission, and an isolation region with ground patterns for reducing interference. This segmentation allows each region to perform its specific function optimally without requiring additional heavy boundary conditions, achieving cross-polarization ratio improvement through internal structural optimization rather than external additions.

Different regions of the radiation board are designed with locally optimized characteristics. The isolation region contains specific ground patterns with particular geometric shapes and distributions tailored to reduce interference in that specific area. The bending portions are strategically positioned to create local electromagnetic field distribution that improves overall cross-polarization performance without adding weight throughout the entire structure.

The bending portions and hollowed-out holes are integrated into a single radiation board component rather than being separate parts. The ground patterns are directly formed on the isolation region of the same board that provides radiation functions. This merging reduces the number of discrete components and assembly steps while achieving the desired isolation performance through the unified structure.

The bending portions create curved three-dimensional structures from the flat radiation board. These bending portions extend outward to form isolation structures that provide electromagnetic shielding and reduce interference between antenna elements. The curved geometry achieves better isolation performance compared to flat structures while maintaining a relatively simple single-piece construction.
