Reactive matching for waveguide-slot-microstrip transitions |
摘要 |
A millimeter wave radar system including a microstrip antenna array that provides reduced return loss at microstrip antenna ports. The millimeter wave radar system includes at least one channel formed in a surface of a metal backing plate and a microstrip antenna array assembly. The assembly includes a plurality of conductive microstrips, a ground plane, and a dielectric substrate disposed between the conductive microstrips and the ground plane to form a plurality of microstrip transmission lines. The metal plate surface is mounted to the ground plate to form at least one waveguide. The ground plane has a plurality of slots formed therethrough to form a plurality of waveguide-to-microstrip transmission line transitions. The conductive microstrips have a plurality of tuning stubs coupled thereto and configured to provide reactive matching for the plurality of waveguide-to-microstrip transmission line transitions.
