Abstract
The "Wheeler Cap" can be used to determine the radiation efficiency of electrically small antennas very accurately. The purpose of this paper is to simulate the improved Wheeler Cap measurement method with a Vivaldi antenna. The WIPL-D simulation tool is used to simulate the antenna in free space and in the Cap. This process can be used to test the accuracy of the improved Wheeler Cap method on an electrically large antenna.
