摘要:
In an exemplary embodiment, a monolithic active solution is configured to generate the fixed spatial beams of a Butler matrix operation or a Blass matrix operation. The exemplary Butler matrix comprises active RF hybrids and vector generators, and is designed for broadband performance in an ultra-compact size, which is size independent of the operating frequency. Furthermore, an exemplary Blass matrix comprises vector generators, active power combiners, and active power splitters. The Blass matrix is designed for broadband performance in an ultra-compact size, which is size independent of the operating frequency. Both the exemplary Butler matrix and exemplary Blass matrix may be configured generate steerable beams. Advantages of both the exemplary Butler matrix and exemplary Blass matrix include that they have neutral or slight positive power gain rather than high losses, and have ultra broadband range which enables operation over multiple frequency bands.
