Publication number: 20240128651Abstract: A wireless device with a slot antenna includes one or more heat spreaders, a PCB with vias to allow current to flow through the PCB, various components disposed on the PCB, and a slot antenna compliment. By layering the components, e.g., heat spreaders, PCB, slot antenna compliment, etc. one or more slot antennas are formed from these components as to integrate the slot antennas into the existing structure. The formed slot antenna is a spiraled shape as to reduce the overall footprint of the slot antenna while keeping the required quarter-wavelength total effective length of an open-slot antenna. The formed slot antenna is wide enough to allow the antenna to accommodate a wide bandwidth and may include a plurality of steps to further allow for tuning of the length of the slot antenna. The wireless device can further include a housing enclosing the internal components.Type: ApplicationFiled: December 12, 2023Publication date: April 18, 2024Inventors: Miroslav SAMARDZIJA, Arthur TUNG, Ming-Tsung SU, Liem Hieu Dinh VO

Publication number: 20230246340Abstract: An antenna element includes an outer conductor and an inner conductor. The outer conductor forms a perimeter of the antenna element. The inner conductor is physically and electrically connected to the outer conductor only at an intermediate connection at an inner portion of the outer conductor. The outer conductor and the inner conductor are arranged to form a slot therebetween. The slot extends around the inner conductor such that each end of the slot is adjacent to the intermediate connection.Type: ApplicationFiled: April 7, 2023Publication date: August 3, 2023Inventors: Miroslav SAMARDZIJA, Arthur TUNG, Brian NAM, Liem Hieu Dinh VO, William J.

Patent number: 11563274Abstract: An integrated metallic component includes a metallic body and an antenna. The metallic body is adapted to at least one of act as a heat exchanger and at least partially enclose electronic components on a Printed Circuit Board (PCB. The antenna includes an antenna element, a short wall, and an antenna feed leg. The antenna element is offset from the metallic body and includes a length extending along a perimeter of the metallic body. The short wall connects the antenna element to the metallic body. The antenna feed leg is offset from the short wall in a direction of the length of the antenna element and adapted to extend from the antenna element to the PCB and to form an electrical connection with an electrical contact for a Radio Frequency (RF) signal trace on the PCB.Type: GrantFiled: October 29, 2020Date of Patent: January 24, 2023Assignee: Plume Design, Inc.Inventors: Miroslav Samardzija, Arthur Tung, Brian Nam, Liem Hieu Dinh Vo

Patent number: 8020006Abstract: A method and network device to process network data is described. The method may comprise receiving the network data and security operation data at a security engine. The security operation data may be associated with a security operation (e.g., encryption, decryption, hashing, or the like) to be performed on the network data. The network data and the security operation data is communicated to a systolic array including a plurality of serially interconnected processing elements each defining a processing stage. Data in each processing stage may be processed in parallel to obtain processed network data. The processed data may be stored in a memory for use by a network processing module and may identify a destination of a packet in the network. In an example embodiment, decryption or encryption may be divided up into a plurality of sub-operations wherein each sub-operation is performed by a processing stage.Type: GrantFiled: February 10, 2006Date of Patent: September 13, 2011Assignee: Cisco Technology, Inc.Inventor: Arthur Tung-Tak Leung, Jr.

Patent number: 7418536Abstract: A processor for use in a router, the processor having a systolic array pipeline for processing data packets to determine to which output port of the router the data packet should be routed. In one embodiment, the systolic array pipeline includes a plurality of programmable functional units and register files arranged sequentially as stages, for processing packet contexts (which contain the packet's destination address) to perform operations, under programmatic control, to determine the destination port of the router for the packet. A single stage of the systolic array may contain a register file and one or more functional units such as adders, shifters, logical units, etc., for performing, in one example, very long instruction word (vliw) operations. The processor may also include a forwarding table memory, on-chip, for storing routing information, and a cross bar selectively connecting the stages of the systolic array with the forwarding table memory.Type: GrantFiled: January 4, 2006Date of Patent: August 26, 2008Assignee: Cisco Technology, Inc.Inventors: Arthur Tung-Tak Leung, Anthony Li, William Lynch, Sharad Mehrotra
