METHOD OF REDUCTION OF FREQUENCY DEPENDENCE OF ABATEMENT AT PASSING OF ELECTROMAGNETIC WAVE THROUGH DIELECTRIC ENVELOPE SIMULTANEOUSLY FOR PARALLEL AND PERPENDICULAR POLARISATION AND FACILITY FOR ITS IMPLEMENTATION (VECTORIAL BLISTER) Russian patent published in 2008 - IPC H01Q1/42 

FIELD: electricity.

SUBSTANCE: introduced Vector blister is intended for protection of linear-polarized antenna, particularly - for fissural phased-array. Method of reduction of frequency dependence of abatement at passing of electromagnetic wave through the dielectric envelope simultaneously for parallel and perpendicular polarisation is achieved by formation form dielectric envelope space figure, which allows in one plane in cross section zigzag shape in increments of preliminary equal to half of wavelength, corresponding to range medium at that envelope is oriented in space thereby, that vector E of electromagnetic wave parallel to surface, where envelope cross section is of zigzag shape. Honeycomb structure allows vectorial properties and functions as polarising filter which efficiently inhibit. Layer which provides blister strength and allows of most high value of dielectric conductivity, is implemented as envelope with superficial instability, which is of zigzag shape in cross-section in increments of preliminary equal to half of wavelength, corresponding to range medium, at that outside current layer is covered by thin-shell protective envelope, providing blister erosion protection and inside - is covered by thin-shell processing envelope, which excludes possibility of blister body particles hit into internal space. Space between outside and inside envelopes is filled by dielectric of low dielectric conductivity and high strength property, e.g. honeycomb structure. Vector blister is oriented in space relative to antenna in such a way that vector E of electromagnetic wave is parallel to plane, where cross-section of envelope is of zigzag shape. Vector blister can be used in the capacity of airplane blister for protection of linear-polarised antenna.

EFFECT: improving of blister radio engineering characteristics by means of creation of optimal conditions for electromagnetic wave passing through blister and providing of high coefficient of passing in broad band.
