An attractive solution for microwave communication technologies is to place a transmit/receive antenna indoors, behind a window. In this case significant costs associated with rooftop rights, raiser and other inbuilding wiring may be avoided. While uncoated window glass introduces relatively small excessive loss into the propagation path, the situation is quite different with coated, “tinted” or laminated glass, which is frequently used to improve thermal and illumination conditions behind it. Insertion loss of such a window glass may be up to 30 dB, depending on type of a glass, carrier frequency, and angle of incidence of the radiation beam. We experimentally demonstrated a possibility of making windows covered by conductive coatings transparent for electromagnetic radiation. This has been achieved by removing a small share of the coating to the effect that non-conducting parts of the window surface split the conductive coating into areas narrow compared to the electromagnetic radiation wavelength.
