1. A radome structure comprising:
an inner tuning layer component having a thickness of at least 3.0 mm and not greater than 12.5 mm, wherein the inner tuning layer component comprises a foam layer having a dielectric constant of at least about 1.0 and not greater than about 3.0, wherein the foam layer comprises a polymethacrylimide (PMD), a polycarbonate (PC), a polyetherimide (PED), a polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), or combinations thereof; and
a laminate component overlying the inner tuning layer component, wherein the laminate component comprises:
a first fiber reinforced dielectric layer comprising a first low dielectric constant material having a dielectric constant of at least about 1.5 and not greater than about 3.5, and wherein the first fiber reinforced dielectric layer comprises polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE), polyamide (PA) or any combinations thereof;
a second fiber reinforced dielectric layer comprising a first high dielectric constant material having a dielectric constant of at least about 2.5 and not greater than about 8.75, and overlying the first fiber reinforced dielectric layer, and wherein the second fiber reinforced dielectric layer comprises glass fibers in a polymer matrix; and
a third fiber reinforced dielectric layer comprising a second low dielectric constant material having a dielectric constant of at least about 1.5 and not greater than about 3.5, and overlying the second fiber reinforced dielectric layer, and wherein the third fiber reinforced dielectric layer comprises polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE), polyamide (PA) or any combinations thereof.
