This paper presents a theoretical evaluation of the phase shifting excitation and load effects in a Transmission Line Excitation Chamber. It is suggested as an alternative for immunity tests because of the restrictions related to canonical chambers. Here, two methods are used to calculate the E-field: a semi-analytic approach and a numerical one. The semi-analytic method is based on the well-known modal expansion while a commercial software is used for numerical simulations. The results regarding the field profile and the related statistical indexes of merit are presented and used to evaluate the chamber performances.
