BROADBAND BLISTER Russian patent published in 2015 - IPC H01Q1/42 

FIELD: transport.

SUBSTANCE: invention related to feeders, primarily, to broadband blisters. Broadband blister comprises one-layer wall of cap-shaped material provided with assembly for fastening to aircraft. It features the wall made of diamagnetic µ ≤ 1, with dielectric permeability $$\epsilon =\frac{1}{\mu },$$ dielectric tg(δ_ε) < 0.0100 and magnetic losses tg(δ_µ) < 0.0100, where dielectric permeability is defined as ε = ε'·(1+i·tg(δ_ε)), while magnetic permeability makes µ = µ'·(1+i·tg(δ_µ)).

EFFECT: higher transmission factor and decreased distortions introduced by blister to incident flow in wide frequency band.
