Patent number: 7317428Abstract: The present invention provides a method and an apparatus for forming an antenna beam from an array antenna having a rear facing side, an aperture, and including a first and a second radiating element. The method comprises injecting a synchronization signal wirelessly from a common source at the rear facing side of the array antenna to provide an initial calibration of the array antenna that synchronizes phase of an output signal from the first and second radiating elements to the common source. The method further comprises compensating a change in phase of the synchronization signal at the first radiating element based on a spatial displacement to synchronize phase of a first portion of the output signal from the first radiating element to the phase of the synchronization signal at the second radiating element in response to the spatial displacement of the first radiating element after the initial calibration of the antenna array.Type: GrantFiled: January 10, 2006Date of Patent: January 8, 2008Assignee: Lucent Technologies Inc.Inventors: Cristian A.

Patent number: 7053832Abstract: A multiple band antenna (and an array of such antennas) includes a first radiating element that radiates at a first band, at least one second radiating element that radiates at a second band, and a frame to hold the radiating elements. The frame disposes the first and second radiating elements in different planes so that cross-band interference is substantially avoided. Alternatively, a multiple band array antenna includes a first array of radiating elements in a first plane and a second array of radiating elements in a second plane. The first plane overlays the second plane. As a result, individual radiating elements in the first array are substantially interspersed with individual radiating elements in the second array. But the first array and the second array are arranged so that individual radiating elements in the first array substantially do not overlap individual radiating elements in the second array.Type: GrantFiled: July 3, 2002Date of Patent: May 30, 2006Assignee: Lucent Technologies Inc.Inventors: Louis Thomas Manzione, Carsten Metz, Richard Alan Warncke

Patent number: 7013452Abstract: An apparatus is disclosed that substantially reduces or eliminates the resonance that occurs in vias that connect the layers of a printed circuit board by electrically coupling a first transmission line in a circuit board to a second transmission line in a circuit board by two electrical paths having substantially the same electrical length. The two electrical paths are created by connecting the first transmission line to a first via which is in turn connected to a second via having a second transmission line with a plurality of connecting electrical paths between the two vias. In one illustrative embodiment, electrical traces are used to connect the top of the first via to the top of the second via and the bottom of the first via to the bottom of the second via.Type: GrantFiled: March 24, 2003Date of Patent: March 14, 2006Assignee: Lucent Technologies Inc.Inventors: Torben Baras, Alan Michael Lyons, Carsten Metz

Patent number: 6958729Abstract: An efficient, low-loss, low sidelobe, high dynamic range phased-array radar antenna system is disclosed that uses metamaterials, which are manmade composite materials having a negative index of refraction, to create a biconcave lens architecture (instead of the aforementioned biconvex lens) for focusing the microwaves transmitted by the antenna. Accordingly, the sidelobes of the antenna are reduced. Attenuation across microstrip transmission lines may be reduced by using low loss transmission lines that are suspended above a ground plane a predetermined distance in a way such they are not in contact with a solid substrate. By suspending the microstrip transmission lines in this manner, dielectric signal loss is reduced significantly, thus resulting in a less-attenuated signal at its destination.Type: GrantFiled: March 8, 2004Date of Patent: October 25, 2005Assignee: Lucent Technologies Inc.Inventor: Carsten Metz
