1. A glazing unit comprising:
a glass panel which is low in reflectance for RF radiation,
a coating system which is high in reflectance for RF radiation disposed on the said glass panel, and
at least one frequencies selective decoated portion of the coating system extending along a plane, P, defined by a longitudinal axis, X, and a vertical axis, Z; having a width, DW, measured along the longitudinal axis, X, and a length, DL, measured along the vertical axis, Z, comprising a first decoated element comprising a plurality of unit cells forming a regular grid of n rows by in columns unit cells, where m and n are positive integers higher than 1 (n>1 and m>1), and a plurality of second decoated elements wherein at least one second decoated element is placed in a unit cell of the first decoated element and wherein no second decoated element is in contact with the first decoated element,
wherein at least one unit cell of the first decoated element has no second decoated element.
