Patent Description:
As more functions and capabilities are added to edge devices, the amount of power consumed and dissipated by the devices increases. Power dissipation becomes more acute when the device is reduced in physical size, which reduces the horizontal and vertical surface area that is available for dissipating thermal energy or heat. Further, many edge devices are deployed or used in environments that prevent the use of (or reduce the effectiveness of) thermal management solutions that require forced airflow (e.g., via a fan, etc.) or cold intake air.

As a result, high performance edge devices, which generate a significant amount of heat, are often shaped to dissipate heat (e.g., are shaped as a quadrilateral cuboid having two elongated faces/sides, etc.) and/or include large casings that house large heat sinks. Yet, purchasers and users of consumer facing edge devices increasingly demand that their device comply with certain size and/or physical design requirements. That is, in addition to high performance and functionality, consumers increasingly demand that their devices have an attractive form factor and a small size that allows the device to be readily placed throughout a home or small office. <CIT>, <CIT>, <CIT> and <CIT> describe known antennas coupled to heatsink arrangements.

The accompanying drawings, which are incorporated herein and constitute part of this specification, illustrate exemplary aspects of the claims, and together with the general description given above and the detailed description given below, serve to explain the features of the claims.

Various aspects will be described in detail with reference to the accompanying drawings. References made to particular examples and implementations are for illustrative purposes, and are not intended to limit the scope of the claims.

Generally, components and circuitry within a computing device (e.g., wireless access point, router, edge device, router, etc.) generate heat or thermal energy, which at excessive levels could have a significant negative impact on the performance and functioning of the computing device. The amount of thermal energy that is generated may depend upon the components included in the computing device, operating conditions, and/or the operations or activities in the computing device. For example, a computing device that wirelessly transmits data for a sustained time period at a high power-level may require that a power amplifier feed the antenna. The power amplifier may generate a significant amount of thermal energy that could have a negative impact on the performance of the computing device. As another example, processors and other components in the computing device generate a significant amount thermal energy when the performing complex tasks, such as video processing, cryptography, or machine learning. The thermal energy generated by these processors/components could have a significant negative impact on the performance and functioning of the computing device.

Many modem computing systems are equipped with heat dissipating structures that help ensure the device does not operate at unsafe temperatures that damage or shorten the operating life of the device. Modern computing systems are often also equipped with radiating structures (antennas) for sending and receiving wireless communications.

In many conventional systems, the heat dissipating structures are separate and independent of radiating structures, and thus compete with one another for product volume (e.g., space with in the device). For these and other reasons, device manufacturers have had to either build devices that are large enough to include both the heat dissipating and radiating structures (e.g., personal computers, laptops, routers, etc.) or build smaller but less powerful devices (e.g., smartphones, IoT devices, etc.) that attempt to balance tradeoffs between performance and power consumption. Device manufacturers that opt to build the small and mid-sized devices often carve away sections of the heat dissipating structure (heatsinks) to make room for the radiating structures (antennas), or vice versa. The tradeoff or reduction in heat dissipation structure size for antenna installation reduces the thermal performance of the device because it decreases the surface area of the heat dissipating structure. This also degrades the radiation patterns on the radiating structures and may otherwise have a negative impact on the device's performance or reliability.

The various embodiments include an integrated heatsink and antenna structure that is suitable for inclusion in small and midsized computing devices and which overcomes the above-described limitations of conventional solutions. The integrated heatsink and antenna structure includes heatsink portions and radio frequency antenna portions. The heatsink portions provide a path for dissipating thermal energy or heat generated by the components in the device (e.g., printed circuit boards, processors, voltage amplifiers, etc.), and the radio frequency (RF) antenna portions allow the device to send and receive wireless communications.

In the embodiments, the integrated heatsink and antenna structure are formed so that radio frequency antenna portions operate to improve the thermal performance of the heatsink portions and/or so that the heatsink portions operate to improve the antenna properties (e.g., radiation patterns, radiation efficiency, bandwidth, input impedance, polarization, directivity, gain, beam-width, voltage standing wave ratio, etc.) of the radio frequency antenna portions. These improvements in thermal performance and/or antenna properties may allow device manufacturers to build more powerful small and midsized devices that provide robust functionality (e.g., via additional antennas, more powerful processors that generate more heat, etc.) and which may be formed into more visually appealing shapes.

The various embodiments may include, use, incorporate, implement, provide access to a variety of wired and wireless communication networks, technologies and standards that are currently available or contemplated in the future, including any or all of Bluetooth®, Bluetooth Low Energy, ZigBee, LoRa, Wireless HART, Weightless P, DASH7, RPMA, RFID, NFC, LwM2M, Adaptive Network Topology (ANT), Worldwide Interoperability for Microwave Access (WiMAX), WIFI, WiFi6,WIFI Protected Access I & II (WPA, WPA2), personal area networks (PAN), local area networks (LAN), metropolitan area networks (MAN), wide area networks (WAN), networks that implement the data over cable service interface specification (DOCSIS), networks that utilize asymmetric digital subscriber line (ADSL) technologies, third generation partnership project (3GPP), long term evolution (LTE) systems, LTE-Direct, third generation wireless mobile communication technology (<NUM>), fourth generation wireless mobile communication technology (<NUM>), fifth generation wireless mobile communication technology (<NUM>), global system for mobile communications (GSM), universal mobile telecommunications system (UMTS), high-speed downlink packet access (HSDPA), 3GSM, general packet radio service (GPRS), code division multiple access (CDMA) systems (e.g., cdmaOne, CDMA2000TM), enhanced data rates for GSM evolution (EDGE), advanced mobile phone system (AMPS), digital AMPS (IS-<NUM>/TDMA), evolution-data optimized (EV-DO), digital enhanced cordless telecommunications (DECT), etc. Each of these wired and wireless technologies involves, for example, the transmission and reception of data, signaling and/or content messages.

Any references to terminology and/or technical details related to an individual wired or wireless communications standard or technology are for illustrative purposes only, and not intended to limit the scope of the claims to a particular communication system or technology unless specifically recited in the claim language.

The term "computing device" may be used herein to refer to any one or all of quantum computing devices, edge devices, Internet access gateways, modems, routers, network switches, residential gateways, access points, integrated access devices (IAD), mobile convergence products, networking adapters, multiplexers, personal computers, laptop computers, tablet computers, user equipment (UE), smartphones, personal or mobile multi-media players, personal data assistants (PDAs), palm-top computers, wireless electronic mail receivers, multimedia Internet enabled cellular telephones, gaming systems (e.g., PlayStation™, Xbox™, Nintendo Switch™, etc.), wearable devices (e.g., smartwatch, head-mounted display, fitness tracker, etc.), IoT devices (e.g., smart televisions, smart speakers, smart locks, lighting systems, smart switches, smart plugs, smart doorbells, smart doorbell cameras, smart air pollution/quality monitors, smart smoke alarms, security systems, smart thermostats, etc.), media players (e.g., DVD players, ROKU™, Apple TV™, etc.), digital video recorders (DVRs), and other similar devices that include a programmable processor and communications circuitry for providing the functionality described herein.

The term "quantum computing device" may be used herein to refer to a computing device or edge device, whether it is a standalone device or used in conjunction with current computing processes, that generates or manipulates quantum bits (qubits) or which utilizes quantum memory states. A quantum computing device may enhance edge computing capability by providing solutions that would be challenging to implement via conventional computing systems. This is especially true with value added computing for leveraging a diverse amount of senor and other input data to arrive at a solution in real time. Through unifying diverse data sources a quantum computing solution at the edge may accelerate machine learning, solve complex problems faster as well as provide the fundamental platform for artificial intelligence nodes at the edge of the network. With the vast array of data delivered by sensors as well state information the quantum computing process may improve the memory allocation though the use of superposition allowing for more information to be simultaneously stored and processed.

The term "edge device" may be used herein to refer to a computing device that includes a programmable processor and communications circuitry for establishing communication links to consumer devices (e.g., smartphones, UEs, IoT devices, etc.) and/or to network components in a service provider, core, cloud, or enterprise network. For example, an edge device may include or implement functionality associated any one or all of an access point, gateway, modem, router, network switch, residential gateway, mobile convergence product, networking adapter, customer premise device, multiplexer and/or other similar devices.

Various different types of antennas are available or contemplated in the future. To focus the discussion on the most important details, some embodiments are described with reference to planar inverted-F antennas. However, nothing in this application should be used to limit the scope of the claims to a specific type antenna unless expressly recited as such in the claims.

Generally, components and circuitry within a computing device generate heat or thermal energy, which at excessive levels may damage or reduce the performance of the computing device. The amount of thermal energy that is generated may vary depending upon the components included in the computing device, operating conditions, and/or the operations or activities in the computing device. For example, a computing device that wirelessly transmits data for a sustained time period at a high power-level may require that a power amplifier feed its antennas. The power amplifier may generate a significant amount of thermal energy that could have a negative impact on the performance of the computing device. As another example, processors and other components in the computing device generate a significant amount thermal energy when the performing complex tasks, such as processing video, using cryptographic technology, or implementing machine learning. The thermal energy generated by these processors/components could damage the device, shorten the operating life of the device, cause the device to abruptly shut down, or otherwise have a negative impact on the device's reliability or performance characteristics.

<FIG> illustrate an integrated heatsink and antenna structure <NUM> in accordance with the embodiments. In particular, the integrated heatsink and antenna structure <NUM> includes a radio frequency (RF) antenna portion <NUM> for sending and receiving wireless communications and heatsink portions 140a, 140b configured to dissipate thermal energy or heat. In addition, RF antenna portion <NUM> operates to improve the thermal performance of one or more of the heatsink portions 140a, 140b.

The RF antenna portion <NUM> may be (or may be plated with) aluminum, copper, stainless steel, beryllium copper, phosphor bronze or any other similar material or composition. The heatsink portions 140a, 140b may be (or may be plated with) aluminum, copper, or any other material or composition suitable for dissipating heat. For example, in an embodiment, the RF antenna portion <NUM> may be copper and the heatsink portions 140a, 140b may be aluminum.

In the examples illustrated in <FIG>, the RF antenna portion <NUM> are formed as a planar inverted-F antenna. In particular, the RF antenna portion <NUM> may include a feed component <NUM>, a ground plane component <NUM>, and a radiating component <NUM>. The radiating component <NUM> may have an L-shape, such that one leg of the L extends substantially parallel to and is offset from the ground plane component <NUM>, while a second leg of the L (e.g., formed after a bend in the radiating component <NUM>) extends substantially perpendicular to the first leg toward the ground plane component <NUM>. In addition, one end of the second leg may be attached to or integrally formed with the ground plane component <NUM> at the grounded end <NUM>.

In some embodiments (e.g., embodiments in which an antenna portion <NUM> is not formed as a planar inverted-F antenna, etc.), a monopole could be designed with the heat sink as ground reference. Further, some embodiments may include a ground plane independent primary radiator (e.g. dipole, etc.) that uses the heatsink as a field shaping structure (dish on a dish antenna).

Returning to examples illustrated in <FIG>, the feed component <NUM> may be electrically coupled to a computing device (not illustrated), in which the integrated heatsink and antenna structure <NUM> is included. Also, the feed component <NUM> may be fixedly secured (e.g., soldered) to the radiating component <NUM> at a feed point <NUM>. In this way, the feed component <NUM> extends from the feed point <NUM>, through an aperture <NUM> in the ground plane component <NUM>, and to a physical connection with the computing device. The feed component <NUM> may include a casing or sheathing <NUM> that insolates the feed component <NUM>. The feed point <NUM> may be disposed between a shorted portion <NUM> and a radiating portion <NUM> of the radiating component <NUM>. The shorted portion <NUM> may extend away from the feed point <NUM>, substantially parallel to the ground plane component <NUM> until the bend, beyond which the remainder of the shorted portion <NUM> extends toward the ground plane component <NUM> such that the grounded end <NUM> ends in contact with the ground plane component <NUM>. In this way, the shorted portion <NUM> may be configured to electrically short one end of the radiating component <NUM> to the ground plane component <NUM>. The radiating portion <NUM> may extend away from the feed point <NUM>, in the opposite direction from the shorted portion <NUM>, extending substantially parallel to the ground plane component <NUM>, but include a remote end that is not attached to any other component or portion of the integrated heatsink and antenna structure <NUM>.

The heatsink portions 140a, 140b each include fin components 114a, 114b that provide thermal resistance and additional surface area for improved thermal performance. The first fin of heatsink portion 140b may provide capacitive tuning to the open end of the <NUM> patches. This may allow the patches to be smaller that would be the case without the fin.

In various embodiments, the fin components 114a, 114b may be (or may be plated with) aluminum, copper, or any other material or composition suitable for dissipating heat. In addition, the fin components 114a, 114b may be formed of a material suitable for also enhancing one or more antenna properties (e.g., radiation patterns, radiation efficiency, bandwidth, input impedance, polarization, directivity, gain, beam-width, voltage standing wave ratio, etc.) of the RF antenna portion <NUM>. A greater or fewer number of fin components 114a, 114b may be included as part of the heatsink portions 140a, 140b (i.e., illustrated as ellipses on the outer right and left sides of <FIG>).

The ground plane component <NUM> is coupled to one or more of the fin components 114a, 114b and arranged to dissipate additional thermal energy and further improve thermal performance, similar to the fin components 114a, 114b. An innermost one of each of the fin components 114a, 114b include tabs 141a, 141b that hold the ground plane component <NUM> in place. Additional components may bias the ground plane component <NUM> into contact with the tabs 141a, 141b, thus securing (i.e., holding) the RF antenna portion <NUM> and the heatsink portions 140a, 140b together. Alternatively, a clip or slot may be provided on or in the innermost ones of the fin components 114a, 114b for securing the ground plane component <NUM> to the fin components 114a, 114b. In this way, securing the ground plane component <NUM> to the fin components 114a, 114b couples the RF antenna portion <NUM> to the heatsink portions 140a, 140b. Also, this coupling produces a synergistic effect of providing an RF antenna portion <NUM> that improves the thermal performance of the heatsink portions 140a, 140b, as well as heatsink portions 140a, 140b that improve the antenna properties of the RF antenna portion <NUM>.

The computing device, in which the integrated heatsink and antenna structure <NUM> is included, may dissipate the same amount of heat and/or achieve the same thermal performance as conventional devices that have larger structures that include larger or a greater number of fin components that occupy more area. In accordance with various embodiments, the integrated heatsink and antenna structure <NUM> may be packaged into a smaller or more compact container and/or to include additional or more powerful components (e.g., additional antennas, more powerful processors that generate more heat, etc.) than conventional devices.

<FIG> illustrate an integrated heatsink and antenna structure <NUM> that includes multiple sets of the integrated heatsink and antenna structure <NUM> described above with regard to <FIG>, in accordance with some embodiments. The integrated heatsink and antenna <NUM> may include numerous antennas. In the illustrated examples, the integrated heatsink and antenna structure <NUM> includes eight (<NUM>) RF antenna portions 120a-h coupled to a heatsink base <NUM>. The heatsink base <NUM> may improve the omnidirectional pattern of the antenna portions (120a-h).

Each of the RF antenna portions 120a-h is coupled to and surrounded by fin components (e.g., 114a-d) integrated into the heatsink base <NUM> and that dissipate thermal energy. For example, four (<NUM>) of the RF antenna portions 120a, 120c, 120e, <NUM> may be disposed on the sides of the integrated heatsink and antenna structure <NUM>, each having a similar configuration to that described with regard to integrated heatsink and antenna structure <NUM> in <FIG>. In contrast, four (<NUM>) more of the RF antenna portions 120b, 120d, 120f, <NUM> may be disposed on the corners of the integrated heatsink and antenna structure <NUM>, each flanked by sets of fin components (e.g., 114b, 114c), but those flanking fin components may be disposed on two different sides of the integrated heatsink and antenna structure <NUM>.

The integrated heatsink and antenna structure <NUM> may include a cavity onto which a processor, computing system, printed circuit board, integrated circuit (IC) chips, a system on chip (SOC), or system in a package (SIP) and/or other similar components may be implemented or placed. In some embodiments, the integrated heatsink and antenna structure <NUM> may include a connector port <NUM> that provides an interface between components of the integrated heatsink and antenna structure <NUM> and other computers or peripheral devices.

In some embodiments, the components/chips may be placed on a heat conducting material (not illustrated separately in <FIG>) that is placed on top of the cavity (or aluminum housing) to help with the heat transfer and to address any imperfections that arise during manufacturing.

In some embodiments, the integrated heatsink and antenna structure <NUM> may dissipate between approximately <NUM> to <NUM> Watts/mm<NUM> (or Watts/inch<NUM>) from the chip to the integrated heatsink and antenna structure <NUM>, from the integrated heatsink and antenna structure <NUM> to ambient air, and/or from the chip to ambient air.

As mentioned above, the integrated heatsink and antenna structure <NUM> may include multiple RF antennas 120a-h. The RF antennas 120a-h may include wideband, multiband, and/or ultrawideband (UWB) antennas. For example, the RF antennas 120a-h may include patch antennas, inverted-L antennas, inverted-F antennas (e.g., planar inverted-F antenna (PIFA), dual frequency PIFA, etc.) or any other antenna suitable for wireless applications. In some embodiments, the RF antennas 120a-h and/or the antenna pattern may be selected based on heatsink characteristics (size, area, amount of heat metal, etc.).

As mentioned above, securing the ground plane component <NUM> to the fin components 114a, 114b couples the RF antenna portions <NUM> to the heatsink portion. In the various embodiments, the ground plane for any of the RF antenna portions <NUM> may be changed so that it is potentially smaller than shown in the figures, but running the entire length behind the heatsink fin components <NUM>.

In some embodiments, the fin components <NUM> may be arraigned into a fin structure that is slightly different for each RF antenna portion 120a-h or for each antenna location. In some embodiments, each of the RF antenna portions <NUM> may be tuned for frequency band and/or modified based on frequency, bandwidth, impedance, proximity to the fin components <NUM> and/or the corresponding fin structure.

<FIG> illustrates a partially exploded view of the integrated heatsink and antenna structure <NUM>. As shown, the RF antenna portions 120a-h may be separated from and/or attached to the heatsink base component <NUM> using securing structures incorporated into some of the fin components.

In some embodiment, the antenna elements/portions may be formed curved of a springy material. The heat sink features may hold the antenna elements/portions flat so that friction (primarily) holds them in place. As such, the RF antenna portions 120a-h may be attached to the heatsink base component <NUM> via a friction fit. In addition, the integrated heatsink and antenna structure <NUM> may be formed to fit into a plastic housing (not illustrated separately in <FIG>) that has features that ensure location of the radiating element so that the antennas do not become detuned by having the structure bent out of shape.

<FIG> illustrates the heatsink base component <NUM> in accordance with various embodiments. In particular, <FIG> shows some of the retaining structures that may be incorporated into some of the fin components for holding and retaining the RF antenna portions (e.g., 120a-h). For example, the corner fin components may have hooked ends <NUM> such that the hooked ends <NUM> on a pair of opposed corner fin components may bend toward one another. The hooked ends <NUM> may be used to secure or trap an RF antenna portion (or components thereof). The RF antenna portion may also be supported by corner mini-fins <NUM> that project out toward the RF antenna portion. In this way, each of the RF antenna portions on the corners of the heatsink base component <NUM> may be trapped between a pair of the hooked ends <NUM> and a set of the corner mini-fins <NUM>. Similarly, the RF antenna portions on the sides of the heatsink base component <NUM> may be trapped between a pair of the tabs 141a, 141b and a set of additional mini-fins <NUM>.

<FIG> and <FIG> illustrate a stackable housing <NUM> for an integrated heatsink and antenna structure in accordance with various embodiments. The stackable housing <NUM> may include a lid <NUM>, an upper rim <NUM>, an upper tray <NUM>, a housing casing <NUM>, housing base <NUM>, and housing feet <NUM>. In accordance with various embodiments, the integrated heatsink and antenna structure (e.g., <NUM>) may be seated on top of the housing base <NUM>. Once the integrated heatsink and antenna structure <NUM> is mounted on the housing base <NUM>, the housing casing <NUM> may be slipped over and surround the integrated heatsink and antenna structure <NUM>. The lid <NUM>, upper rim <NUM>, and upper tray <NUM> may then close off the assembly by being secured on top of the housing casing <NUM>. Additional components and/or circuitry may be located between the integrated heatsink and antenna structure and the housing base <NUM>. Similarly, components and/or circuitry may be located between the lid <NUM> and the upper tray <NUM>.

In various embodiments, the stackable housing <NUM> may be stacked on top of or below another stackable housing <NUM>, which then allows multiple integrated heatsink and antenna structures (e.g., <NUM>) to be used together in a compact arrangement. To stack the stackable housings <NUM>, the lid <NUM>, upper rim <NUM>, and upper tray <NUM> of all but the uppermost stackable housing <NUM> are removed, which may expose one integrated heatsink and antenna structure below to another integrated heatsink and antenna structure above. For example, <FIG> illustrates two of the stackable housings shown in <FIG> and <FIG> stacked on top of and couple to one another in accordance with various embodiments.

<FIG> illustrates an example computing system <NUM> that may be used with integrated heatsink and antenna structure <NUM> in accordance with some embodiments. In the example illustrated in <FIG>, the computing system <NUM> includes an SOC <NUM>, a clock <NUM>, and a voltage regulator <NUM>.

In overview, an SOC may be a single IC chip that contains multiple resources and/or processors integrated on a single substrate. A single SOC may also include any number of general purpose and/or specialized processors (packet processors, etc.), memory blocks (e.g., ROM, RAM, Flash, etc.), and resources (e.g., timers, voltage regulators, oscillators, etc.). The components in an SOC may generate a significant amount of thermal energy or heat, and thus the placement of the components within the SOC, the location of the SOC within the integrated heatsink and antenna structure <NUM>, and other thermal management considerations are often important.

With reference to <FIG>, the SOC <NUM> may include a digital signal processor (DSP) <NUM>, a modem processor <NUM>, a graphics processor <NUM>, an application processor <NUM> connected to one or more of the processors, memory <NUM>, custom circuitry <NUM>, system components and resources <NUM>, a thermal management unit <NUM>, and an interconnection/bus module <NUM>. The SOC <NUM> may operate as central processing unit (CPU) that carries out the instructions of software application programs by performing the arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

The thermal management unit <NUM> may be configured to monitor and manage the device's junction temperature, surface/skin temperatures and/or the ongoing consumption of power by the active components that generate thermal energy in the device. The thermal management unit <NUM> may determine whether to throttle the performance of active processing components (e.g., CPU, GPU, LCD brightness), the processors that should be throttled, the level to which the frequency of the processors should be throttled, when the throttling should occur, etc..

The system components and resources <NUM> and custom circuitry <NUM> may manage sensor data, analog-to-digital conversions, wireless data transmissions, and perform other specialized operations, such as decoding data packets and processing video signals. For example, the system components and resources <NUM> may include power amplifiers, voltage regulators, oscillators, phase-locked loops, peripheral bridges, temperature sensors (e.g., thermally sensitive resistors, negative temperature coefficient (NTC) thermistors, resistance temperature detectors (RTDs), thermocouples, etc.), semiconductor-based sensors, data controllers, memory controllers, system controllers, access ports, timers, and other similar components used to support the processors and software clients running on a device. The custom circuitry <NUM> may also include circuitry to interface with other computing systems and peripheral devices, such as wireless communication devices, external memory chips, etc..

Each processor <NUM>, <NUM>, <NUM>, <NUM> may include one or more cores, and each processor/core may perform operations independent of the other processors/cores. For example, the SOC <NUM> may include a processor that executes a first type of operating system (e.g., FreeBSD, LINUX, OS X, etc.) and a processor that executes a second type of operating system (e.g., MICROSOFT WINDOWS <NUM>). In addition, any or all of the processors <NUM>, <NUM>, <NUM>, <NUM> may be included as part of a processor cluster architecture (e.g., a synchronous processor cluster architecture, an asynchronous or heterogeneous processor cluster architecture, etc.).

The processors <NUM>, <NUM>, <NUM>, <NUM> may be interconnected to one another and to the memory <NUM>, system components and resources <NUM>, and custom circuitry <NUM>, and the thermal management unit <NUM> via the interconnection/bus module <NUM>. The interconnection/bus module <NUM> may include an array of reconfigurable logic gates and/or implement a bus architecture (e.g., CoreConnect, AMBA, etc.). Communications may be provided by advanced interconnects, such as high-performance networks-on chip (NoCs).

The SOC <NUM> may further include an input/output module (not illustrated) for communicating with resources external to the SOC, such as the clock <NUM> and the voltage regulator <NUM>. Resources external to the SOC (e.g., clock <NUM>, etc.) may be shared by two or more of the internal SOC processors/cores.

In addition to the SOC <NUM> discussed above, the various embodiments may include or may be implemented in a wide variety of computing systems, which may include a single processor, multiple processors, multicore processors, or any combination thereof.

The processors may be any programmable microprocessor, microcomputer or multiple processor chip or chips that can be configured by software instructions (applications) to perform a variety of functions, including the functions of the various aspects described in this application. In some wireless devices, multiple processors may be provided, such as one processor dedicated to wireless communication functions and one processor dedicated to running other applications. Typically, software applications may be stored in the internal memory <NUM> before they are accessed and loaded into the processor. The processor may include internal memory sufficient to store the application software instructions.

As mentioned above (e.g., with reference to <FIG> and <FIG>, etc.), in some embodiments the heatsink base component <NUM> may include mini-fins <NUM> that secure or trap side RF antenna portions (e.g., RF antenna portions 120a, 120c, 120e and <NUM>, etc.) or components thereof. In other embodiments, the RF antenna portions may be located only on the corners of the heatsink base component <NUM>.

<FIG> illustrates an integrated heatsink and antenna structure in which the RF antenna portions are located on the corners but not the sides. Rather than mini-fins <NUM> (illustrated in <FIG>), the side portions include full-sized fin components <NUM> that provide thermal resistance and additional surface area for improved thermal performance. The fin components <NUM> also secure a grounding plate <NUM> that couples the RF antenna portions <NUM> to the heatsink portions of the integrated heatsink and antenna structure. As such, the grounding plate <NUM> enhances the thermal performance of the heatsink portions, enhances the radio properties of the RF antenna portions, and/or improves the performance of the SOC components (e.g., components <NUM>-<NUM>). In the example illustrated in <FIG>, the integrated heatsink and antenna structure also includes a connector port <NUM> that provides an interface between components of the integrated heatsink and antenna structure and other computers or peripheral devices.

In some embodiments, the integrated heatsink and antenna structure may include retaining structures. The retaining structures may be incorporated into some of the fin components for holding and retaining the RF antenna portions. For example, the corner fin components may have hooked ends <NUM> such that the hooked ends <NUM> on a pair of opposed corner fin components may bend toward one another. The hooked ends <NUM> may be used to trap an RF antenna portion. The RF antenna portion may also be supported by corner mini-fins or similar structures that project out toward the RF antenna portion. In this way, each of the RF antenna portions on the corners of the heatsink base component may be trapped between a pair of the hooked ends <NUM> and a set of the corner fins.

As mentioned above, the grounding plate <NUM> is coupled to one or more of the fin components <NUM> and arranged to dissipate additional thermal energy and further improve thermal performance, similar to the fin components <NUM>.

Some of the fin components <NUM> include tabs <NUM> that hold the ground plane component <NUM> in place. Additional components may bias the grounding plate <NUM> into contact with the tabs <NUM>, thus securing (i.e., holding) or trapping the grounding plate <NUM> to the heatsink portion and/or to a corner antenna portion. Alternatively, a clip or slot may be provided on or in one or more of the fin components for securing the grounding plate <NUM> to the fin components. This coupling produces a synergistic effect of extending an RF antenna portion that improves the thermal performance of the heatsink portions and/or improves its radio properties (e.g., radio patterns).

<FIG> are isometric views that illustrate that a grounding plate <NUM> may be integrated into each side of the integrated heatsink and antenna structure.

<FIG> are illustrations of the grounding plate <NUM> in accordance with some embodiments. The grounding plate <NUM> may include ridges <NUM> and slots <NUM>, any or all of which function to improve radio properties (e.g., radio patterns) of the RF antenna portions. For example, the center slot <NUM> illustrated in <FIG> may operate to improve the radio properties (e.g., radio patterns, etc.) of RF antenna portions of the integrated heatsink and antenna structure (e.g., by further tuning the antenna, etc.).

As used in this application, the terms "component," "module," "system," and the like may refer to a computer-related entity, such as, but not limited to, hardware, firmware, a combination of hardware and software, software, or software in execution, which are configured to perform particular operations or functions. For example, a component may be, but is not limited to, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a wireless device and the wireless device may be referred to as a component. One or more components may reside within a process and/or thread of execution and a component may be localized on one processor or core and/or distributed between two or more processors or cores. In addition, these components may execute from various non-transitory computer readable media having various instructions and/or data structures stored thereon. Components may communicate by way of local and/or remote processes, function or procedure calls, electronic signals, data packets, memory read/writes, and other known network, computer, processor, and/or process related communication methodologies.

However, features shown and described with respect to any given aspect are not necessarily limited to the associated aspect and may be used or combined with other aspects that are shown and described. Further, the claims are not intended to be limited by any one example aspect. For example, one or more of the operations of the methods may be substituted for or combined with one or more operations of the methods.

The foregoing method descriptions and the process flow diagrams are provided merely as illustrative examples and are not intended to require or imply that the operations of various aspects must be performed in the order presented.
