Abstract
A planar beamformer () for use with a array antenna includes a dielectric sheet () defining first () and second () broad sides. A strip conductor () on the first side crosses over a similar strip conductor () 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.
