Summary:
This paper presents a general technique for an effective near-field to far-field transformation based on the complex source beam (CSB) method. In this technique, a set of CSBs launched from the center of antenna under test is used to represent the antenna’s radiation. The weightings of CSBs are found by matching the near-fields measured on a pre-described surface in the conventional measurement systems. All three conventional measurement techniques including planar, cylindrical and spherical measurement systems are examined to validate the CSB method with accuracy comparisons in the nearand far-field patterns.
