Abstract: An electronic power divider for radio frequency signals, and an electronic system containing such electronic power divider, includes one or more inputs designed to be fed by an electromagnetic radio frequency signal having a predetermined wavelength; at least two outputs for the radio frequency signal, each of which is connected to the same input; electric paths adapted to connect each output to the corresponding input, and a system of selective variation of the electric impedance associated with each of the electric paths during the passage of the signal. The impedance variation system is adapted to vary the impedance associated with the paths discreetly between a lower and an upper value, and to simultaneously maintain the value of the impedance associated with two or more paths at least at the lower value.

Abstract: A method to regulate a conditioning apparatus including a conditioning body inside which conditioning means are disposed, suitable to modify the state of a flow of air to cause a determinate effect in an internal environment, where the method provides to receive an indication of target environmental parameters to be reached in the internal environment, detect the actual parameters in the environment, and regulate the functioning of the conditioning means by means of a control and command unit.

Abstract: The present invention refers to a reconfigurable antenna structure. The antenna structure comprises a radiating structure comprising one or more first radiating elements and a secondary radiating structure, operationally associated with said primary radiating structure. Said secondary radiating structure comprises a plurality of second radiating elements that can be selectively electrically connected/disconnected to each other to vary the configuration of said secondary radiating structure, so as to vary the radiating properties of the antenna structure. The antenna structure also comprises first reactive loads, electrically connected between said primary and secondary radiating structures, and second reactive loads, electrically connected to said secondary radiating structure.

Abstract: The present invention refers to a reconfigurable antenna structure. The antenna structure comprises an active radiating structure comprising at least an active radiating element, a passive radiating structure comprising at least a passive radiating element, a ground plane structure comprising at least a ground plane element and at least a first circuitry element to selectively electrically connect/disconnect said passive radiating element with/from said ground plane element. The ground plane structure comprises regulating means of the current distribution along said ground plane structure, when said antenna structure emits/receives an electromagnetic radiation.

Abstract: An antenna apparatus may include a reflective layer connected to a ground, one or more first antennas disposed on the reflective layer, wherein each first antenna includes a first active element and one or more first parasitic elements; one or more first switching devices, each associated with corresponding one of the one or more first parasitic elements in at least one of one or more first antennas, one or more second antennas disposed on the reflective layer, wherein each second antenna includes a second active element and one or more second parasitic elements, and one or more second switching devices, each associated with corresponding one of the one or more second parasitic elements in at least one of one or more second antennas. The first antennas operate at a first frequency. The second antennas operate at a second frequency different from the first frequency.
