Description
A compact, passive embedded ceramic stacked patch antenna designed to support both SDARS and DSRC in a single, space-efficient footprint. The stacked dual-patch approach enables strong performance across both bands, helping simplify integration where SDARS and DSRC capability are required in one antenna element.
- Dual-band stacked patch design: Supports SDARS and DSRC with a dual-feed patch assembly.
- Compact embedded form factor: 25 x 25mm footprint with low overall height for tight integration spaces.
- Automotive-focused integration: Suitable for OEM automotive implementations, including shark-fin style roof-mounted antenna systems.
- Optimized on a reference ground plane: Tuned and tested on a 70 x 70 mm ground plane for center positioning.
