A Two-Port Model for Antennas in an Arbitrary Environment



Jason B. Coder, John M. Ladbury, Mark Golkowski


We present an improved model for characterizing fundamental antenna parameters based on the concept of a passive realizable two-port network. The proposed model is consistent with circuit theory based approaches and allows for quantitative description and subsequent experimental determination of antenna efficiency, loss and imperfections. A derivation of the model is given along with analytical and numerical solution techniques. Application of the proposed antenna model is shown to yield a lower bound of antenna radiation efficiency. Derivation and application of the model is carried out in the context of a reverberation chamber, but the results are potentially applicable to an arbitrary environment.
