Abstract :
The purpose of this paper is to extend the Improved Wheeler Cap measurement method to cases where the cavity is expected to overmode. Numerical processing methods will be applied to reduce the error introduced by overmoding cavity losses. The WIPL-D simulation tool is used to simulate the antenna in free space and in the Cap.
