| Patent | Steerable microwave antenna and method therof | The present document discloses a steerable-beam microwave antenna, arranged for steering a beam relative to a longitudinal axis of the antenna, comprising: a discrete transmitarray comprising a plurality of sub-wavelength phase-shifting unit-cells, rotatably mounted for rotating about said longitudinal axis, having an aperture orthogonal to said longitudinal axis; a feeder for emitting and/or receiving a microwave signal to and/or from the discrete transmitarray, comprising at least one rotatable feeding part; wherein the unit-cell layout of the discrete transmitarray has a phase distribution which superimposes a phase gradient along a transversal axis orthogonal to said longitudinal axis and a rotationally-symmetric phase correction centred on said longitudinal axis. It is also disclosed a method for operating and a method of manufacturing said steerable-beam microwave antenna. | 2023 |
| Patent | Waveguide Power Divider | WAVEGUIDE POWER DIVIDER COMPRISING IN SEQUENCE: A FIRST SECTION COMPRISING A DOUBLE-CRESTED WAVEGUIDE FOR INPUTTING A SIGNAL; A SECOND SECTION COMPRISING A DOUBLE-CRESTED TAPERED PORTION FOR MATCHING THE WAVEGUIDE IMPEDANCE OF A FUNDAMENTAL MODE ALONG THE TAPER AND A SEPTUM FOR SPLITTING THE INPUT SIGNAL; A THIRD SECTION COMPRISING TWO DOUBLE-CRESTED WAVEGUIDES SEPARATED BY A SPACING FOR PROPAGATING THE SPLIT SIGNAL TO THE OUTPUT; WHEREIN THE DOUBLE-CRESTED TAPER COMPRISES A LONGITUDINALLY CONTINUOUS PROFILE BETWEEN THE FIRST SECTION AND THE THIRD SECTION. THE RESPECTIVE BEAMFORMING AND ANTENNA NETWORKS ARE ALSO DISCLOSED. | 2023 |
| Patent | Device with mirror-integrated transparent antenna for radio frequency identification system | THE PRESENT INVENTION RELATES TO A NEW CONCEPT OF TRANSPARENT ANTENNAS FOR RFID READERS, INTEGRATED IN A MIRROR FOR USE IN FITTING ROOMS, TO ENABLE THE AUTOMATIC READING OF RFID TAGS ATTACHED TO THE GARMENT BEING TRIED ON AND SIMPLE CUSTOMER INTERACTION WITH A STORE'S PRODUCT DATABASE. O INVENTION IS BASED ON A DEVICE (1) WITH AN ANTENNA PRINTED (2) ON A SUBSTRATE OF LOW SUBSTRATE (6), OPTICALLY TRANSPARENT, INTEGRATED INTO THE GLASS PART OF A MIRROR (3) AND FED BY A SLIT (4) OPEN IN THE GROUND PLANE, EXCITED BY A TRANSMISSION LINE (5) PRINTED ON THE BACK OF THE MIRROR (9). THE DEVICE (1), IN ADDITION TO ELIMINATING THE VISUAL IMPACT OF CONVENTIONAL ANTENNAS, GUARANTEES THE CONFINEMENT OF THE READING TO THE REGION IN FRONT OF THE MIRROR, WITHOUT UNWANTED READINGS FROM ADJACENT TESTERS, ELIMINATING THE NEED FOR USE OF ELECTROMAGNETIC BARRIERS. THE MANUFACTURING PROCESS, AS WELL AS THE USED ARE QUITE SIMPLE AND T | 2011 |
| Patent | Wireless Passive Voting Device and System | The present invention relates to wireless passive voting device comprising at least a carrier layer made of dielectric material over which is arranged a plurality of RFID tags, each RFID tag corresponding to a selectable vote option or answer; and at least a selected RFID tag masking layer comprising one electromagnetically opaque single film or a plurality of film strips, with said RFID tags of the carrier layer, a region for RFID visibility and RFID tag reading, and which allows detection and unambiguous identification of said RFID tag corresponding to the selected vote option or answer. The present invention further relates to a wireless passive voting system using one or more devices, as well as to a voting method. | 2009 |
| Patent | DEVICE FOR READING RADIO FREQUENCY IDENTIFYERS FOR VOLUMETRIC CONFINING OF THE DETECTION REGION | Device for reading radio frequency identifiers (RFID) ensuring volumetric confinement at UHF of the detection of RFID tags to a desired volume above a reading surface, which includes one or more metallic transmission lines (6) printed on a dielectric substrate (8), on a metallic reference ground plane (7), an RFID reader or interrogator (3) at one end and a load (10) at the other end whereby a structure (19,21,22,23), that comprises the reading surface, in which the one or more transmission lines (6), the dielectric substrate (8) and the metallic reference ground plane (7) are embedded or attached, and the electric fields (11) are contained in planes perpendicular to the one or more transmission lines (6) with one to five wavelengths that extend over all or part of the length of the reading surface, and wherein the dialectric substrate (8) has a low permittivity, less than 1,5 and the width of the transmission line (6) is comprised between 8 and 15% of the wavelength. | 2008 |
| Patent | Compact antenna with mechanical beam guidance for tracking mobile terminals in wireless communications | THIS INVENTION RELATES TO A TRACKING ANTENNA, PARTICULARLY SUITABLE FOR WIRELESS COMMUNICATIONS WHERE THERE IS A NEED FOR AUTOMATIC GUIDANCE OF THE ANTENNA'S RADIATION BEAM IN THE DIRECTION OF ANOTHER MOBILE TERMINAL. THE ORIENTATION OF THE BEAM IS OBTAINED BY A MECHANICAL PROCESS. THE ANTENNA CONSISTS OF A FIXED PRIMARY SOURCE PRIMARY SOURCE (1), WITH MODERATE GAIN, WHICH ILLUMINATES A DIELECTRIC LENS (2) WITH AXIAL SYMMETRY THAT CAN BE TILTED AND ROTATED AROUND. CAN TILT AND ROTATE AROUND TWO ORTHOGONAL AXES TO ALLOW THE RADIATION BEAM TO BE ORIENTED IN AZIMUTH (13) AND ELEVATION (11). THE LENS HAS TWO SURFACES WHOSE GEOMETRY IS DESIGNED TO COLLIMATE THE RADIATION BEAM IN THE DIRECTION OF ITS AXIS OF SYMMETRY, WHATEVER ITS OF SYMMETRY, WHATEVER THE INCLINATION OF THE LENS WITH RESPECT TO THE AXIS OF THE PRIMARY SOURCE. THIS ALLOWS FOR HIGH BEAM SCANNING ANGLES. THE ANTENNA CAN BE USED FOR BOTH TRANSMITTING AND RECEIVING, PROVIDING A SOLUTION WITH HIGH RADIATION PERFORMANCE PERFORMANC | 2008 |
