Abstract

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.
