Publication number: 20080062062Abstract: This invention is in the field of base station antennas for wireless communications. The present invention refers to a slim multi-band antenna array for cellular base stations, which provides a reduced width of the base station antenna and minimizes the environmental and visual impact of a network of cellular base station antennas, in particular in mobile telephony and wireless service networks. A multiband antenna array comprises a first set of radiating elements operating at a first frequency band and a second set of radiating elements operating at a second frequency band, said radiating elements being smaller than ?/2 or smaller than ?/3, being (?) the longest operating wavelength. The ratio between the largest and the smaller of said frequency bands is smaller than 2.Type: ApplicationFiled: August 31, 2005Publication date: March 13, 2008Inventors: Carmen Borau, James Kirchhofer, Anthony Teillet, Carles Baliarda

Publication number: 20080011509Abstract: A high frequency electromagnetic circuit is disclosed as being patterned on a metallic or superconducting film on top of a dielectric in a plurality of configurations. A part of the circuit such as the characteristic strip or slot of the configurations is shaped in a novel space-filling geometry which allows a significant size reduction of a circuital component. Miniature transmission lines, capacitors, inductors, resistors, filters, and oscillators can be manufactured this way.Type: ApplicationFiled: June 22, 2007Publication date: January 17, 2008Inventors: Carles Baliarda, Juan O'Callaghan Castella, Edouard Rozan, Juan Collado Gomez, Nuria Duffo Ubeda

Publication number: 20070279289Abstract: Antennae in which the corresponding radiative element contains at least one multilevel structure formed by a set of similar geometric elements (polygons or polyhedrons) electromagnetically coupled and grouped such that in the structure of the antenna can be identified each of the basic component elements. The design is such that it provides two important advantages: the antenna may operate simultaneously in several frequencies, and/or its size can be substantially reduced. Thus, a multiband radioelectric behaviour is achieved, that is, a similar behavior for different frequency bands.Type: ApplicationFiled: October 17, 2006Publication date: December 6, 2007Applicant: FRACTUS, S.A.Inventors: CARLES BALIARDA, CARMEN BORAU, JAUME PROS, JORDI CASTANY

Publication number: 20070159401Abstract: The present invention relates to a handset and generally of any handheld device, which includes an antenna for receiving and transmitting electromagnetic wave signals. More in particular, the invention is related to handsets of the clamshell or flip-phone type. An electromagnetic bra structure is introduced to correct the position of the lobes of the handheld radiation pattern, so that the radiation and sensitivity of the hand held device is increased in the horizontal plane or generally to the other desired directions. The electromagnetic bra structure comprises at least one conducting surface arranged over at least one side of a ground plane of the handset, so that a resonance circuit having a high impedance at an operating frequency of the antenna is establish, to block currents and electromagnetic fields from entering a region of the ground plane.Type: ApplicationFiled: February 28, 2005Publication date: July 12, 2007Inventors: Carles Baliarda, Jaume Pros

Publication number: 20070152886Abstract: A novel geometry, the geometry of Space-Filling Curves (SFC) is defined in the present invention and it is used to shape a part of an antenna. By means of this novel technique, the size of the antenna can be reduced with respect to prior art, or alternatively, given a fixed size the antenna can operate at a lower frequency with respect to a conventional antenna of the same size.Type: ApplicationFiled: March 15, 2007Publication date: July 5, 2007Applicant: FRACTUS, S.A.Inventors: CARLES BALIARDA, EDOUARD ROZAN, JAIME PROS

Publication number: 20070152887Abstract: Multiband monopole antennas are disclosed. The antennas disclosed can include a substrate for mounting conductors, one or more conductors for receiving networking signals mainly in a first frequency band, and one or more conductors for receiving networking signals mainly in a second frequency band. The conductors can have a polygonal shape or the conductors can have a linear, space-filling, or grid dimension shape. The conductors can be connected at a feed point. One or more antenna can be incorporated into a single printed circuit board. When multiple antennas are used with the same printed circuit board, the conducting material of the printed circuit board located between the antenna attachment points can be interrupted to improve the isolation of each antenna.Type: ApplicationFiled: January 28, 2005Publication date: July 5, 2007Inventors: Jordi Castany, Carles Baliarda, Carmen Borau

Publication number: 20070046548Abstract: Antennas for use in mobile communication devices are disclosed. The antennas disclosed can include a substrate with a base, a top, a front side and a back side; a first conductor can be located on the first side of the antenna substrate; and a second conductor can be located on the second side of the antenna substrate. The conductors can have single or multiple branches. If a conductor is a single branch it can, for example, be a spiral conductor or a conducting plate. If a conductor has multiple branches, each branch can be set up to receive a different frequency band. A conductor with multiple branches can have a linear branch and a space-filling or grid dimension branch. A conducting plate can act as a parasitic reflector plane to tune or partially tune the resonant frequency of another conductor. The first and second conductors can be electrically connected.Type: ApplicationFiled: January 28, 2005Publication date: March 1, 2007Applicant: FRACTUS S.A.Inventors: Jaume Pros, Carles Baliarda

Publication number: 20060082505Abstract: A miniature antenna includes a radiating arm that defines a grid dimension curve. In one embodiment, the radiating arm includes a planar portion and at least one extruded portion. The planar portion of the radiating arm defines the grid dimension curve. The extruded portion of the radiating arm extends from the planar portion of the radiating arm to define a three-dimensional structure. In one embodiment, the miniature antenna includes a first radiating arm that defines a first grid dimension curve within a first plane and a second radiating arm that defines a second grid dimension curve within a second plane. In one embodiment, the miniature antenna includes a radiating arm that forms a non-planar structure.Type: ApplicationFiled: August 12, 2005Publication date: April 20, 2006Inventors: Carles Baliarda, Jordi Soler-Castany, Juan Ortigosa-Vallejo, Jaume Anguera-Pros

Publication number: 20050259013Abstract: The present invention relates generally to a new family of antennas with a multiband behaviour and a reduced size. The general configuration of the antenna consists of a multilevel structure which provides the multiband behaviour, combined with a multilevel and/or space-filling ground-plane. The multilevel structure consists of two arms of different length that follow a winding parallel path spaced by a winding parallel gap (parallel to the arms) with a substantially similar shape as each of said arms, that is, with a similar winding path as the arms. The resulting antenna covers the major current and future wireless services, opening this way a wide range of possibilities in the design of universal, multi-purpose, wireless terminals and devices.Type: ApplicationFiled: December 23, 2004Publication date: November 24, 2005Inventors: David Gala Gala, Carles Baliarda, Jordi Castany

Publication number: 20050146481Abstract: Antenna arrays which can work simultaneously in various frequency bands thanks to the physical disposition of the elements which constitute them, and also the multiband behaviour of some elements situated strategically in the array. The configuration of the array is described based on the juxtaposition or interleaving of various conventional mono-band arrays working in the different bands of interest. In those positions in which elements of different multiband arrays come together, a multiband antenna is employed which covers the different working frequency bands. The advantages with respect to the classic configuration of using one array for each frequency band are: saving in cost of the global radiating system and its installation (one array replaces several), and its size and visual and environmental impact are reduced in the case of base stations and repeater stations for communication systems.Type: ApplicationFiled: November 12, 2004Publication date: July 7, 2005Inventor: Carles Baliarda
