The aperture in an infinite ground plane backed by a rectangular waveguide is used as near‐field probe. The reflection coefficient of the radiator, which is also an open‐end of a rectangular waveguide, is computed and compared with the reflection coefficients, when the probe is at different positions in the near‐field. Computations have also been carried out to find the induced probe voltage, when the probe scanning in transverse plane (planar scanning) is at a distance z 1 from the radiator. Good agreement is obtained between measured and MOM results. © 2006 Wiley Periodicals, Inc.
