SLOT ARRAY ANTENNA FOR VEHICLE RADAR |
| 摘要 |
A slot array antenna for a vehicle radar system is provided. The antenna includes a cavity which separates a magnetic field signal applied through a feeding waveguide while maintaining phase and amplitude and which radiates such signals to the each radiating slot. A slot array antenna includes a 2-by-2 unit cell arrangement and a feeding plate member that forms a feeding waveguide. In addition, a first slot plate member includes a coupling slot, a cavity plate member forms a cavity, and a second slot plate member has a plurality of sequentially laminated radiation slots. Further, the cavity includes a partition wall for impedance matching |
