Gradient-Based Near-Field Antenna Characterization in Planar Geometry
Keywords:
Antenna measurements, near field/far field transformation, planar scanning, probe compensation, singular valuesAbstract
A near field characterization technique, based on the optimization of the Singular Value Behavior, is here accelerated by using the analytical expression of the gradient of the relevant objective functional. This solution allows to conveniently tackle the cases of electrically large antennas.
