Characterization of elliptically polarized antenna by complex effective length

In this paper the interaction of elliptically polarized electromagnetic field and generalized receiving antenna is described by means of complex effective length. In the analysis the ellipse of complex effective length, similar to the polarization ellipse, is introduced, which gives physical interpretation of complex effective length. The complex effective length- having close relation to the polarization of the antenna- is used for describing the characteristics of elliptically polarised antennas. Based on this analysis it can be stated that the complex effective length is a universal characteristic of antennas and from it all the important antenna parameters can be derived. The complex effective length gives a suitable description of the receiving features of the antenna.
