  • Patent number: 5666127
    Abstract: An energy transmission arrangement is formed as a subarray panel which emits a microwave energy signal to a target location on the basis of a pilot signal received from the target location. The subarray panel includes a transmission antenna divided into a subarray having a plurality of antenna elements for transmission of the energy signal. The subarray panel further includes pilot signal receiving antennas and thus each subarray panel may function independently and may thus be made lighter and more compact.
