Zusammenfassung:	A via-less beamformer provided from a plurality of circuits elements having circuit layouts selected to mitigate unwanted reactive coupling there between. At least one of the plurality of circuit elements is provided having a circuit layout selected based upon reactive field theory. In one embodiment, a circuit layout may be selected by: determining which circuit features of the circuit elements produce reactive fields in response to a signal provided thereto, separating the total field into a modal set and determining the modal weighting coefficients based on geometrical and/or design features of the of the circuit elements. In one embodiment the via-less beamformer comprises one or more via-less combiner/divider circuits. In one embodiment the via-less beamformer comprises one or more branch hybrid coupler circuits. In one embodiment the via-less beamformer comprises one or more via-less combiner/divider circuits and one or more branch hybrid coupler circuits.
