Abstract
A charging device is provided for communicating with one or more consumer devices for remotely charging at least one of them upon demand of the consumer. The charging device comprises a transmitter unit associated with an antenna unit comprising a power antenna for defining at least one charging zone for transmitting charging power toward it; a receiver for receiving signals from consumers located within the charging zone; and a controller unit configured to be responsive to a request signal from a consumer indicative of demand for charging, to initiate a charging process of the consumer by radiation from the power antenna toward the consumer to supply power required for operating a functional unit of the consumer. The power antenna may comprise an array of directional antenna elements, each defining the charging zone within a different angular segment of entire charging space defined by a radiation pattern of the antenna array.
