A charging device (200) is provided for communicating with one or more consumer devices (300) for remotely charging at least one of them upon demand of the consumer. The charging device (200) comprises a transmitter unit associated with an antenna unit comprising a power antenna configured to define at least one charging zone for transmitting charging power to the at least one charging zone; a receiver for receiving signals from consumers (300) located within the charging zone; and a controller unit. The controller is configured and operable to be responsive to a request signal from a consumer(300) indicative of demand for charging, to initiate a charging process of the consumer by radiation from the power antenna toward said consumer (300) to supply power required for operating a functional unit of said consumer(300). 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. |
