FIELD: radio engineering, communication.
SUBSTANCE: invention relates to antennas and can be used to effectively concentrate radiation from a distributed source to an object, located in a common focal zone. A versatile device for transmitting radiation from the source to the object contains two antennas. Each of these is manufactured in the shape of a truncated segment of a convoluted surface. The antennas are installed so that to form the common focal zone with a changeable configuration, concentration and volume. The changes are done by altering the distance between the antennas. The distributed radiation source is located in an exposing zone of at least one antenna and in the common focal zone of both antennas.
EFFECT: increase of the radiation transmission efficiency from the source to the object.
