BROAD-BAND BLISTER Russian patent published in 2009 - IPC H01Q1/42 

FIELD: physics; radio.

SUBSTANCE: invention concerns antenna-feeder arrangements mainly to broad-band antenna blisters. The goal of invention is decrease in distortions brought by a blister in the field of an incident wave in a working range of frequencies. The wall in a broad-band blister, containing a wall from a dielectric substance in the form of a cap, supplied with the attachment assembly to a flying machine, is executed from a substance with frequency-dependent distribution of a dielectric coefficient The geometrical thickness of a wall is chosen from condition thus electric thickness of the wall is multiple to a half-wave length in a working range of frequencies; thus, α, α_min and α_max - the average, minimum and maximum angle of incidence of an electromagnetic wave for the chosen blister shape, F_av - average frequency of a working range, c - light speed, n=1, 2… - natural number.

EFFECT: decrease in deformation in the field of an incident wave and improvement of radiotechnical characteristics.
