  • Reduced-layer isolated planar beamformer
    Patent number: 6842631
    Abstract: A planar beamformer (700) for use with a array antenna includes a dielectric sheet (210) defining first (210us) and second (2101s) broad sides. A strip conductor (32b) on the first side crosses over a similar strip conductor (32c) on the second side. In order to reduce coupling between the conductors in a stripline or microstrip context, a set of stripline- (or microstrip)-to-coplanar-waveguide transitions are incorporated into each strip conductor adjacent the crossover, and the crossover region conductors are narrowed. The transitions include petal elements coplanar with the strip conductors.
