Paper Abstract

Each device ror radiation registration in radio range containes an antenna. Mainly it is the antenna dimention the sensitivity o such a device belnp determined by. Can the antenna ror registration or' more short wave radiation be constructed? The main reature o antenna action is tile conversion o the insident radiation mode into the mode passing through antennaAt this moment the radiation brightness (which is equivalent to a number or photons per mode ) can increase . In accordance WI th the geometry optics (Shtraubel theorem) the lenth and mirror systems cannot raise the radiation brightness in principle and cannot be treated an antennas.
