Abstract
A method to design antennas with broadband characteristics. In an exemplary embodiment, a method comprises loading an antenna structure with multiple reactive loads. The multiple loads are synthesized by applying the theory of Characteristic Modes. Another exemplary embodiment includes an antenna adapted to have broadband characteristics. One example is a wire dipole antenna. In an exemplary embodiment, a loaded antenna may be adapted to resonate an arbitrary current over a wide frequency band. The loads may require non-Foster elements when realized. Exemplary embodiments may include the broadband characteristics of the both the input impedance at the terminal of the antenna as well as the radiation pattern.
