Patent number: 9793963Abstract: Aspects of the subject disclosure may include, for example, an integrated circuit that includes at least one die having transceiver circuitry that generates outbound signals that convey outbound data and that receives inbound signals that convey inbound data. A first array of antenna elements arranged along the top portion of the IC package operate in conjunction with the transceiver circuitry to transmit at least a first portion of the outbound signals as first wireless transmissions and/or generate at least a first portion of the inbound signals from first wireless receptions. A second array of antenna elements arranged along the bottom portion of the IC package operate in conjunction with the transceiver circuitry to transmit at least a second portion of the outbound signals as second wireless transmissions and/or to generate at least a second portion of the inbound signals from second wireless receptions. Other embodiments are disclosed.Type: GrantFiled: November 25, 2014Date of Patent: October 17, 2017Assignee: AVAGO TECHNOLOGIES GENERAL IP (SINGAPORE) PTE.Inventors: Alfred Grau Besoli, Nicolaos Georgiou Alexopoulos, Jesus Alfonso Castaneda, Chryssoula Angelakis Kyriazidou

Patent number: 9537201Abstract: A reconfigurable antenna structure includes first and second reconfigurable antennas, a configuration module, and an antenna processing circuit. The first reconfigurable antenna is configured, in response to a first configuration signal, to have a first radiation pattern and to have a first frequency bandwidth and the second reconfigurable antenna is configured, in response to a second configuration signal, to have a second radiation pattern and to have a second frequency bandwidth. The configuration module is configured to generate the first and second configuration signals. The antenna processing circuit is configured to send one or more transmit signals to one or more of the first and second reconfigurable antennas for transmission via one or more of the channels of interest and receive one or more receive signals from the one or more of the first and second reconfigurable antennas.Type: GrantFiled: September 30, 2013Date of Patent: January 3, 2017Assignee: BROADCOM CORPORATIONInventors: Nicolaos Georgiou Alexopoulos, Seunghwan Yoon, Alfred Grau Besoli

Patent number: 9515379Abstract: A poly spiral antenna includes spiral antenna sections and interconnecting traces. A first spiral antenna section has a first interwoven spiral pattern and a first excitation configuration to provide a first radiation pattern component. A second spiral antenna section has a second interwoven spiral pattern and a second excitation configuration to provide a second radiation pattern component. A third spiral antenna section has a third interwoven spiral pattern and a third excitation configuration to provide a third radiation pattern component. The interconnecting traces couple the first, second, and third spiral antenna sections together such that the first, second, and third radiation pattern components form a radiation pattern of the poly spiral antenna.Type: GrantFiled: September 30, 2013Date of Patent: December 6, 2016Assignee: BROADCOM CORPORATIONInventors: Nicolaos Georgiou Alexopoulos, Seunghwan Yoon, Alfred Grau Besoli

Patent number: 9407338Abstract: An antenna array structure includes a plurality of antennas, wherein a first antenna has a first geometric shape, provides a first radiation pattern, and has a first frequency bandwidth. A second antenna has a second geometric shape to provide a second radiation pattern and has a second frequency bandwidth. The first and second frequency bandwidths at least partially overlap to include channels of interest. An antenna processing circuit sends one or more transmit signals to one or more of the antennas for transmission via one or more of the channels of interest and receives one or more receive signals from the one or more of the antennas or from another one or more of the antennas via the one or more of the channels of interest or from another one or more of the channels of interest.Type: GrantFiled: September 30, 2013Date of Patent: August 2, 2016Assignee: BROADCOM CORPORATIONInventors: Nicolaos Georgiou Alexopoulos, Seunghwan Yoon, Alfred Grau Besoli
