Radome wall design having broadband and mm-wave characteristics

摘要: The invention describes a multi-layer radome construction which is termed D-sandwich and allows excellent transmission efficiency over areas of the entire spectrum DC to at least 100 GHz. wall comprises core layer low dielectric constant material bounded by intermediate layers high themselves are additional material. Each has substantial electrical effect upon performance as well being strength provides structural rigidity radome. may be further provided with one or more protective surface coatings for certain environmental conditions, without destroying desired characteristics constant, loss tangent thickness various materials in designed provide frequency angular range desired. thicknesses also minimize insertion return losses thereby minimizing loading radar transmitters relatively insensitive aspect angle arbitrary wave polarization.
