Abstract:
A method for tuning a radome comprising the steps of:providing a radome structure having at least one layer of dielectric material, said radome structure having a transmission frequency response that describes, as a function of frequency, a level of attenuation experienced by a radio frequency signal incident upon a first surface of said radome structure before emerging from a second surface of said radome structure, said transmission frequency response including a first resonance region having a center frequency at a first frequency value and a second resonance region having a center frequency at a second frequency value that is different from said first frequency value; anddisposing a conductive frequency selective surface (FSS) upon a first portion of said radome structure, said disposing step causing said center frequency of said second resonance region to shift from said second frequency value to a third frequency value, said third frequency value being different from said second frequency value, wherein both said first and second resonance regions with said center frequencies at said first and third frequency values, respectively, are present after said disposing step.
