FIELD: antenna technology.
SUBSTANCE: invention relates to antenna technology, in particular to a billboard containing cellular telephone communication antennas inside its body, acting through a coating permeable to electromagnetic waves. The technical result of the invention is the hidden action of antennas through a coating permeable to electromagnetic waves. The technical result is achieved by the fact that a billboard is proposed that includes a frame consisting of multiple interconnected profiles forming at least one grid, in which each grid has an inner surface and an outer surface, a metal sheet coating on the outer surface of each grid, at least one window made in a coating of metal laminate, a laminar section of non-metallic material permeable to electromagnetic waves, covering the outer surface of the grid at the locations of the windows, at least one cellular telephone antenna located entirely on the inside of the grid at the locations of the windows, the response profiles forming the window frame are made of a non-metallic material that is permeable to electromagnetic waves, while the profiles are metal, and the antennas are completely hidden in the frame.
EFFECT: technical result of the invention is the hidden action of antennas through a coating permeable to electromagnetic waves.
