A Near-Field Propagation Law & A Novel Fundamental Limit to Antenna Gain Versus Size,” IEEE Antenna and Propagation Society

This paper presents a theoretical analysis of the near field channel in free space. Then this paper validates the theoretical model by comparison to data measured in an open field. The results of this paper are important for low frequency RF systems, such as those operating at short range in the AM broadcast band. Finally this paper establishes a novel fundamental limit for antenna gain versus size. 1
