Abstract : The patent relates to radar target cross section control achieved by antenna elements that are terminated by impedance loads whose impedance values decrease with increasing incident electromagnetic wave frequency. An impedance load that accomplishes this over a wide frequency band and that uses only passive elements is disclosed. It comprises a length of transmission-line terminated in its own characteristic impedance and having a multiplicity of reflector elements disposed along its length. The reflector elements are geometrically spaced and electrically tuned such that maximum reflection (or scattering) of electromagnetic waves occurs at points progressively closer to the load input terminal as electromagnetic wave frequency increases.
