Patent number: 9136885Abstract: Embodiments of the invention relate to wireless communications networks, and more specifically to an antenna apparatus for cellular wireless systems. Increasing data capacity of cellular wireless systems places increasing demands on the capacity of the two way connection, known as backhaul, between a cellular base station and a telecommunications network such as the PSTN backhaul, since this is the connection that has to convey the wireless-originating traffic to its destination, often in an entirely different network. Known backhaul links include leased lines, microwave links, optical fiber links or radio resources for relaying backhaul traffic between base stations. The fixed line solutions are expensive to implement and maintain, while the radio solutions antenna configurations that are not ideal for relaying data between base stations.Type: GrantFiled: June 27, 2014Date of Patent: September 15, 2015Assignee: Apple Inc.Inventors: Simon Gale, Andrew Urquhart

Patent number: 8805388Abstract: Embodiments of the invention relate to wireless communications networks, and more specifically to an antenna apparatus for cellular wireless systems. In some embodiments, a method of transceiving signals in a wireless communications network is described. The method includes receiving, by user equipment, a signal in a time slot and a frequency band from a transceiver system, the transceiver system configured to transceive at least one other signal from one or more base stations in at least one other time slot and at least one other frequency band via at least two antenna systems. The frequency bands at least partially overlap and transmissions of the signals are in at least a portion of the wireless communications network.Type: GrantFiled: April 17, 2013Date of Patent: August 12, 2014Assignee: Apple Inc.Inventors: Simon Gale, Andrew Urquhart

Patent number: 8525733Abstract: The present invention relates to an RE antenna structure that includes a planar structure and a loading plate, such that the planar structure is mounted between a ground plane and the loading plate to form an RF antenna. The loading plate may be about parallel to the ground plane and the planar structure may be about perpendicular to the loading plate and the ground plane. The loading plate may allow the height of the RF antenna structure above the ground plane to be relatively small. For example, the height may be significantly less than one-quarter of a wavelength of RF signals of interest. The planar structure may include two conductive matching elements to help increase the bandwidth of the RF antenna structure.Type: GrantFiled: February 12, 2013Date of Patent: September 3, 2013Assignee: Apple Inc.Inventors: Dean Kitchener, Andrew Urquhart

Patent number: 8514139Abstract: Embodiments of the invention relate to an antenna structure and are particularly suited to array antennas. An antenna according to an embodiment of the invention employs an enclosure having an aperture in one end; in preferred arrangements the aperture provides the enclosure with a substantially open end, over which the cover is placed. The cover has a slot therein, of a smaller size than the size of the aperture presented by the open ended enclosure and the slot in the cover then acts as the radiating slot.Type: GrantFiled: December 28, 2007Date of Patent: August 20, 2013Assignee: Apple, Inc.Inventors: David Adams, Andrew Urquhart, William Waddoup, Dean Kitchener, Steven Hall, Simon Gale

Publication number: 20110181482Abstract: Embodiments of the invention relate to an antenna structure and are particularly suited to array antennas. Conventionally, an antenna of the cavity-backed slot-radiating type comprises a slot formed in an end of an electrically conductive enclosure, which slot may be energised by a radiating element in registration with the slot. A feed network may connect to the radiating element via a transmission line formed by a conductive track on a feed layer located between the enclosure and an electrically conductive cover. A slot is formed in the section of the cover that covers the end of the cavity in which a slot is formed, such that the two slots are of substantially the same size and shape. A problem with this structure is that the cavity is difficult to mould in one piece and it can be difficult to achieve alignment of respective slots; as a result it is relatively costly to manufacture. Also, it is difficult to insert dielectric material into the enclosure to adjust the performance parameters of the antenna.Type: ApplicationFiled: December 28, 2007Publication date: July 28, 2011Inventors: David Adams, Andrew Urquhart, William Waddoup, Dean Kitchener, Steven Hall, Simon Gale

Publication number: 20110183867Abstract: This invention relates to a method of screening arrays of polymers having pre-determined surface energies. The polymer arrays of the present invention can be used to screen for microorganism adherence. More specifically the arrays can be used to screen for adherence of particular bacteria or fungi to particular polymers in the array. Furthermore, this invention relates to a method combining in-situ polymer synthesis with physico-chemical characterisation of the resulting polymer array and subsequent biological assays of bacterial or fungal adherence. This allows for high throughput screening and characterisation of candidate polymers which are not susceptible to bacterial or fungal adherence or which can be used to support bacterial or fungal adherence where such is required. The arrays can also be used to screen for inhibition or promotion of biofilm formation.Type: ApplicationFiled: August 7, 2008Publication date: July 28, 2011Applicants: UNIVERSITY OF NOTTINGHAM, MASSACHUSETTS INSTITUTE OF TECHNOLOGYInventors: Martyn Christopher Davies, Morgan Alexander, Paul Williams, Robert Langer, Daniel Anderson, Andrew Urquhart
