Resumen:
Radar technology, particularly at the 76-81 GHz band, plays a central role in ADAS (Advanced Driver Assistance Systems) development, offering precise measurements and robustness in obstacle detection. This work presents a gap waveguide-based, metal-only antenna, combining low transmission losses with scalable design. The proposed 1×8 slotted array antenna, fed through groove gap waveguide technology, provides multi-channel and multibeam operation. Its metal-only construction ensures seamless integration into vehicle chassis while maintaining efficiency in automotive frequency bands. The proposed structure behavior has been validated through full-wave simulations in CST Microwave Studio. The results present a potential candidate for antennas with multibeam performance in E-band.
