    Abstract

    In this paper, the bandwidth limitations of dipoles matched with negative impedance components are discussed. In theory, infinite impedance bands are possible with non-Foster impedances, but in practice the fields stored inside the smallest sphere enclosing the antenna limit the band. Both theoretical and practical achievable bandwidths as well as non-Foster component tolerance issues are reported in this paper.
