On Determining the Maximum Emissions From Electrically Large Sources

Abstract

This paper examines the use of measurements of the total radiated power from an arbitrary source, combined with theory-based directivity or quality factor estimates, to accurately predict the maximum electric field radiated by the source either at a line-of-sight distance or in a resonant volume. The total radiated power approach avoids source rotations during testing and is an efficient alternative to present emission test methods. Examples of simulated (random source set) and measured (box with holes) planar-cut radiation-patterns for electrically large sources are presented. Both simulated and measured data agree well with theoretical estimates.
