This paper describes a new procedure allowing the use of measured antenna sources in commercially-available numerical computational environments.
The procedure is fully general and can be used with common antennas in complex environments of arbitrary shape and complexity. The accuracy and effectiveness of the procedure has been illustrated by an example. An offset-fed reflector has been measured and the measurements compared to a simulation using the proposed numerical modeling procedure, with measurement of the isolated feed and numerical modeling of the reflector. Finally, the results have been compared to a dedicated computation analysis of the full antenna model.
