The figures below show the amplitude and phase distribution of the X and Y components the electric field slightly above the surface of the microstrip-fed patch antenna measured at 2.349GHz. Both 2D intensity plots and 3D surface plots are shown. The field amplitude is expressed in dBV/m, while the phase is expressed in degrees. The field scan data can be imported to [[EM.Cube]] with more visualization capabilities. For example, the field components can be combined to produce very informative vector field plots.

== The Perfect Solution for Characterizing Ultra-wideband Antenna Systems ==
Characterization of the radiation patterns Far-field characterization of ultra-wideband Antenna Systems is a very challenging task. Whether using an anechoic chamber or a conventional near-field scanning systems, in both cases you need have to utilize different types of metallic antennas with different sizes at different frequency bands.
