Description:
BACKGROUND OF THE INVENTION 
   An electronic device, such as a portable electronic device, may be equipped with one or more antennas configured for facilitating wireless communication based on one or more standards such as, for example, Wi-Fi, WiMAX, GPRS, WCDMA, CDMA2000, etc. The antenna may be supported by an antenna-carrying assembly. Typically, there are two types of antenna-carrying assemblies: add-on antenna-carrying assemblies and built-in antenna carrying assemblies. 
   A typical add-on antenna-carrying assembly may be represented by a PC card antenna-carrying assembly. A PC card antenna-carrying assembly may have a PC card configuration and may be inserted into a PC card slot of an electronic device, such as a notebook computer or PDA. Generally, a significant portion of the PC card antenna-carrying assembly may protrude from the enclosure of the electronic device for reception and transmission of electromagnetic signals (or RF signals). 
   The protrusion may cause significant inconvenience associated with the use of the electronic device. For example, a user of the electronic device may have to remove the PC card antenna-carrying assembly before the electronic device can be stowed or transported in a case or bag. Further, the PC card antenna-carrying assembly and the electronic device may be disposed separately when the electronic device is stowed or transported. As a result, the PC card antenna-carrying assembly may not be available when wireless communication is needed. If the PC card antenna-carrying assembly is not removed from the electronic device, the protrusion may increase the likelihood of damage to the PC card antenna-carrying assembly or the electronic device during transportation. 
   A typical built-in antenna-carrying assembly may represent a rotatable part of an electronic device. In general, a built-in rotatable antenna-carrying assembly may be mechanically coupled with an enclosure of an electronic device through a pivot mechanism. The rotatable antenna-carrying assembly may be rotated to a deployed position for reception and transmission of electromagnetic signals, and may be rotated to a stowed position when not in use. 
   The rotatable antenna-carrying assembly may represent a protrusion outside the enclosure of the electronic device. If the rotatable antenna-carrying assembly and the pivot mechanism are not sufficiently reinforced, the rotatable antenna-carrying assembly and/or the pivot mechanism may be prone to damage. If the rotatable antenna-carrying assembly or the pivot mechanism is damaged, repair/replacement of the rotatable antenna-carrying assembly or the pivot mechanism may be inconvenient or event difficult, given the coupling among the rotatable antenna-carrying assembly, the pivot mechanism, and the enclosure. If the rotatable antenna-carrying assembly and the pivot mechanism are to be sufficiently reinforced, significant material and manufacturing costs may be incurred. 
   When employed with a notebook computer, a prior art antenna-carrying assembly, such, as a PC card antenna-carrying assembly or a rotatable antenna-carrying assembly, may generally be disposed at the base unit of the notebook computer. Accordingly, the antenna may be positioned close to the table on which the notebook is placed. As a result, electromagnetic signals may be obstructed by the table, and the efficiency of signal reception and transmission may be suboptimal. 
   Further, if the notebook computer has a metal enclosure that is opaque to electromagnetic waves, given that the antenna is disposed at the base unit, electromagnetic signals may be further blocked by the metal enclosure of the display module of the notebook computer. As a result, the efficiency of signal reception and transmission may be further compromised. In order to mitigate the problem, manufacturers may need to avoid metal materials when designing notebook computer enclosures.

   An embodiment of the present invention is an antenna-carrying assembly for facilitating wireless communication using an electronic device.

The first attraction element is configured to magnetically couple the antenna-carrying assembly with a track and to slide along the track. At least one of the first attraction element and the track includes one or more magnetic elements.

   DETAILED DESCRIPTION OF EMBODIMENTS 
   The present invention will now be described in detail with reference to a few embodiments thereof as illustrated in the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without some or all of these specific details. In other instances, well known process steps and/or structures have not been described in detail in order to not unnecessarily obscure the present invention. 
   One or more embodiments of the invention relate to an antenna-carrying assembly (e.g., a boom assembly) for facilitating wireless communication employing an electronic device. The antenna-carrying assembly may include a body, which may be transparent or at least not opaque to electromagnetic signals (or RF signals). The antenna-carrying assembly may, also include one or more antenna elements (e.g., a flex antenna) carried by the body. The antenna-carrying assembly may further include a first attraction element carried by the body. The first attraction element may be configured to magnetically couple the antenna-carrying assembly with a track and to slide along the track. 
   At least one of the first attraction element and the track may include one or more magnetic elements or one or more ferrous elements. In one or more embodiments, each of the first attraction element and the track may include one or more magnetic elements. A magnetic element may include one or more magnets or Halbach arrays with one or more directed/tuned magnetic fields. 
   The track may be disposed along an edge of the electronic device. The track may include a plurality of discretely distributed attraction elements configured to tune tactile feedback, such as resistance, bumps, or variations of resistance or bumps, perceived by a user of the electronic device. 
   Alternatively or additionally, the track may be disposed in a mating structure (e.g., a trench) configured to accommodate the antenna-carrying assembly. The mating structure may be part of a module, e.g., a display module, of the electronic device. A substantial portion of the antenna-carrying assembly may be flush with at least a portion of an outer surface of an enclosure of the electronic device when the antenna-carrying assembly is in a stowed state. 
   The antenna-carrying assembly may also include a second attraction element carried by the body. The second attraction element may be configured to magnetically couple a tip of the antenna-carrying assembly with an electrical contact of the electronic device when the antenna-carrying assembly in a stowed state.

The one or more tap elements may represent a plurality of tap elements (or feed points) for multi-band communication. The one or more tap elements may have a stud configuration. 
   The antenna-carrying assembly may also include an insert-molded shunt element carried by the body. The inserted-molded shunt may be configured to augment/tune a magnetic field of the first attraction element. The inserted-molded shunt may also be configured to secure the first attraction element in place though magnetic coupling. Accordingly, the first attraction element may, be dropped into and secured in a holding structure (or slot structure) of the body without relying on a fastening mechanism (e.g., a screw) or structure (e.g., a dovetail or groove). The holding structure may also be configured to limit movement of the antenna-carrying assembly relative to the track. 
   The antenna-carrying assembly may also include a tactile feature (e.g., a grid or ridge feature) configured to enable the antenna-carrying assembly to be slid by a user of the electronic device without being seen by the user. 
   One or more embodiments of the invention relate to an electronic device. For example, the electronic device may represent one or more of a computing device (e.g., a computer), a computer peripheral (e.g., a display), a communication device (e.g., a cellular phone), a media player (e.g., an MP3 player), etc. 
   The electronic device may include the aforementioned antenna-carrying assembly and track. The electronic device may also include a label/coating disposed on at least one of the track and the first attraction element and configured to tune friction between the track and the first attraction element.

   Holding structure  341  may be configured to substantially limit movement of antenna-carrying assembly  320  to translation along mating structure  210  and break away from mating structure  210 . 
   Antenna section  336  may include one or more antenna elements  328  carried by body  325 . Body  325  may be formed of a material, such as plastic, that is not opaque to electromagnetic signals.

The one or more antenna elements  328  may include a label/coating or may be covered by a label/coating, for protection and cosmetics/aesthetics. 
   Antenna section  336  may also include one or more tap elements, such as tap element  322 . Tap element  322  may be electrically coupled to an electrical contact, such as electrical contact  214  illustrated in the example of  FIG. 2 , when antenna-carrying assembly  320  is in a deployed state, such that an electrical path between circuitry inside an electronic device, such as electronic device  250  illustrated in the example of  FIG. 2 , and the one or more antenna elements  328  may be established. 
   Tap element  322  may include a mating feature  323  configured to engage electrical contact  214 . When antenna-carrying assembly  320  slides into the deployed state, i.e., when tap element  322  is coupled to electrical contact  214 , at least one of tap element  322  and electrical contact  214  may produce an acoustic and/or tactile signal, such as a click. Advantageously, the user may confirm that antenna-carrying assembly  320  is in the deployed state without looking at antenna-carrying assembly  320 . 
   Tap element  322  may have a stud configuration. Tap element  322  may be configured to limit movement of antenna-carrying assembly  320  when antenna-carrying assembly  320  has been in the deployed state. For example, by contacting an end of a mating structure, such as mating structure  210  illustrated in the example of  FIG. 2 , tap element  322  may stop antenna-carrying assembly  320  from further sliding in a direction  281  shown in the example of  FIG. 2 . 
   Second magnetic section  337  may represent a tip portion of antenna-carrying assembly  320 .

Second magnetic section  327  may also include a rib structure  329  surrounding second attraction element  324  configured to fit with an end portion of a mating structure, such a mating structure  210  illustrated in the example of  FIG. 2 . 
   With magnetic coupling between electrical contact  214  and second attraction element  324  and between track  212  and first attraction element  321 , antenna-carrying assembly  320  may be secured, e.g., in mating structure  210  shown in the example of  FIG. 2 , in the stowed state. An outer surface of antenna-carrying assembly  320  may be flush with an outer surface of enclosure  200  of electronic device  250 . As a result, antenna-carrying assembly may be smoothly integrated with enclosure  200 . Advantageously, electronic device  250  may be conveniently stowed and transported, and aesthetic/cosmetic design requirements of electronic device  250  may also be satisfied. Further, the magnetic coupling between  327  and electrical contact  214  may prevent antenna-carrying assembly  320  from warping. 
   The utilization of magnetic coupling may also facilitate break-away of antenna-carrying assembly  320  when antenna-carrying assembly  320  is not in the stowed state and when an undesirable force is applied to antenna-carrying assembly  320 . Advantageously, the break-away may prevent damage to antenna-carrying assembly  320  and electronic device  250 . Magnetic coupling may also allow for modular antenna-carrying assemblies, e.g. assemblies specifically optimized for different wireless standards. Further, the utilization of magnetic coupling may also facilitate easy replacement of antenna-carrying assembly  320 .

Shunt  464  may also be configured to secure first attraction element  421  through magnetic coupling, such that first attraction element  421  may be secured in holding structure  441  without relying on complicated fastening devices (such as a screw) or complicated fastening structures (such as a dovetail or groove). Advantageously, manufacturing of antenna-carrying assembly  120  may be simplified. Between first attraction element  421  and shunt  464 , glue or adhesive may be applied to reinforce the coupling. 
   Body  425  may, have one or more structures, such as tapered structure  427 , which may automatically fit/align with one or more structures, such as tapered structure  487  of mating structure  110 . Tapered structures  427  and  487  may also allow for break-away and insertion of antenna-carrying assembly  120  from electronic device  150  in more than one direction vector. 
   Electronic device  150  may include label/coating  401  disposed on at least one of track  112  and first attraction element  421 . Label/coating  401  may be configured to tune the friction between track  112  and first attraction element  421 . Alternatively or additionally, label/coating  401  may be configured to provide cosmetic and/or tactile effects. 
     FIG. 4B  illustrates a cross-sectional view of electronic device  150  with antenna-carrying assembly  120  in the stowed state illustrated in the example of  FIG. 1A  in accordance with one or more embodiments of the present invention. For example,  FIG. 4B  may represent cross-sectional view B indicated in the example of  FIG. 1A . As illustrated in  FIG. 4B , antenna-carrying assembly  120  may include one or more antenna elements  451  carried by body  425 . Antenna-carrying assembly  120  may also include label/coating  452  configured to protect the one or more antenna elements  451  and to satisfy one or more cosmetic/aesthetic design requirements. 
   Electronic device  150  may further include a space  423  between track  112  (or label/coating  401 ) and antenna-carrying assembly  120  such that friction exerted on antenna-carrying assembly  120  may be minimized during translation/movement of antenna-carrying assembly  120  relative to electronic device  150 . 
     FIG. 4C  illustrates a cross-sectional view of electronic device  150  with antenna-carrying assembly  120  in the stowed state illustrated in the example of  FIG. 1A  in accordance with one or more embodiments of the present invention. For example,  FIG. 4C  may represent cross-sectional view C as indicated in the example of  FIG. 1A . In one or more embodiments, as illustrated in the example of  FIG. 4C , electrical contact  414  may represent a ball element of a ball detent that includes a spring  418  and a barrel  419  configured to support/house electrical contact  414 . 
   With the ball detent configuration, electrical contact  414  may be adjustable to one or more oblique points of contact on a second attraction element  424  of antenna-carrying assembly  120 . Further, electrical contact  414  may be able to distribute force and distribute wear such that durability of electrical contact  414  may be advantageously improved. 
   Second attraction element  424  may include one or more magnetic/ferrous elements for magnetic coupling with electrical contact  414 . Second attraction element  424  may also include a mating feature  434  configured to engage electrical contact  414 . When antenna-carrying assembly  120  slides into the stowed state, the engagement of electrical contact  414  and mating feature  434  may provide an audible/acoustic and/or tactile confirmation to the user of electronic device  150 . Mating feature  434  may also enhance the magnetic coupling between electrical contact  414  and second attraction element  424  by creating larger contact area between attraction elements. Electrical contact  414  may include one or more magnetic elements configured to reinforce the magnetic coupling between electrical contact  414  and second attraction element  424 . 
   Antenna-carrying assembly  120  may include a shunt  444  insert-molded inside body  425 . Shunt  444  may be configured to augment/tune the magnetic field of second attraction element  424 . Shunt  444  may also be configured to secure second attraction element  424  in place through magnetic coupling, such that second attraction element  424  may be secured in place without relying on a complicated fastening mechanism or structure. 
     FIG. 4D  illustrates a cross-sectional view of electronic device  150  with antenna-carrying assembly  120  in the deployed state illustrated in the example of  FIG. 1B  in accordance with one or more embodiments of the present invention. For example,  FIG. 4D  may represent cross-sectional view D indicated in the example of  FIG. 1B . 
   As illustrated in the example of  FIG. 4D , antenna-carrying assembly  120  may include tap element  462  contacting the one or more antenna elements  451 . In the deployed state, tap element  462  may also contact and electrically connect with electrical contact  414 . Tap element  462  and electrical contact  414  may also make non-contact electrical connection, for example capacitive coupling across a distance through a gap or material. Accordingly, tap element  462  plays the role of an electrical bridge between the one or more antenna elements  451  and electrical contact  414 . 
   Tap element  462  may include a mating feature  463  configured to engage electrical contact  414 , which may directly or indirectly connect with enclosure  100  of electronic device  150 . Tap element  462  and electrical contact  414  may be biased toward each other given the magnetic coupling between first attraction element  421  and track  112  illustrated in the example of  FIG. 4A . Tap element  462  and electrical contact  414  may also include magnetic or attraction elements for magnetic coupling. Accordingly, tap element  462  and electrical contact  414  may serve as a mechanical bridge between antenna-carrying element  120  and enclosure  100 . 
   In one or more embodiments, electrical contact  414  may have a ball detent configuration supported by spring  418  and housed by barrel  419 . Spring  418  may bias electrical contact against tap element  462  to reinforce electrical coupling. Barrel  419  may be formed of a conductive material, such as brass plated with gold. Accordingly, barrel  419 , electrical contact  414  and tap element  462  form part of the electrical path between the one or more antenna elements  451  and electrical circuitry inside electronic device  150 . 
   With the ball detent configuration, electrical contact  414  may have self-cleaning capability such that contamination on the surface of electrical contact  414  may be minimized, and electrical contact  414  may efficiently and effectively conduct electrical signals. The force provided by spring  418  also ensures optimal contact between electrical contact and tap element  462  to reinforce the electrical conductivity. The ball detent configuration may also enable oblique mating and un-mating (e.g. not along axial direction), creating robust electrical contact for a broad range of mating conditions. 
     FIG. 5A  illustrates a mating structure  510  of an electronic device  550  for accommodating an antenna-carrying assembly in accordance with one or more embodiments of the present invention.  FIG. 5B  illustrates an antenna-carrying assembly  520  in accordance with one or more embodiments of the present invention. Antenna-carrying assembly  520  may be accommodated mating structure  510  in a stowed state. Antenna-carrying assembly  520  may be guided by at least one of track  512  and one or more of walls  511  and  513  of mating structure  510  when translating from the stowed state to a deployed state. 
   Mating structure  510  may include a plurality of electrical contacts, such as electrical contacts  511  and  512 . 
   Antenna-carrying assembly  520  may includes a plurality of tap elements, such as tap elements  521  and  522 , electrically coupled to one or more antenna elements  528 , for example, for facilitating multi-band wireless communication. Tap elements  521  and  522  may be electrically (and magnetically) coupled to electrical contact  511  and  522 , respectively, when antenna-carrying assembly  520  is in the deployed state. 
   Antenna-carrying assembly  520  may also include a plurality of tip attraction elements, such as attraction elements  531  and  532 . Attraction elements  531  and  532  may be magnetically coupled to electrical contact  511  and  522 , respectively, when antenna-carrying assembly  520  is in the stowed state, such that a tip of antenna-carrying assembly  520  may be secured and flush with an outer surface of enclosure  500  of electronic device  550 . 
   As can be appreciated from the foregoing, embodiments of the present invention may optimize signal transmission and reception efficiency in wireless communication, based on one or more novel features. For example, embodiments of the invention optimally position antenna-carrying assemblies (and therefore antennas) such that obstruction of signal transmission and reception by a table (and/or a metal enclosure of an electronic device) may be minimized. Advantageously, embodiments of the invention may enable utilization of metal material in electronic device enclosures because the obstruction of the enclosure to an antenna may be minimized when an antenna-carrying assembly is in a deployed state. 
   Embodiments of the present invention may also provide a reliable electrical path reinforced by magnetic coupling and/or force applied by a spring. With magnetic coupling, embodiments of the invention may also prevent damages to electronic devices and antenna-carrying assemblies, since an antenna-carrying assembly may readily break away from a mating portion of an electronic device when a force is undesirably exerted on the antenna-carrying assembly. With magnetic coupling, embodiments of the present invention also enable easy replacement of antenna-carrying assemblies. 
   Keeping an antenna-carrying assembly flush with an enclosure of an electronic device when the antenna-carrying assembly is in a stowed state, embodiments of the present invention may provide space efficiency, and convenience in stowing electronic device. Embodiments of the present invention may also meet aesthetic/cosmetic requirements in electronic device design. 
   Embodiments of the present invention may be intuitive for a user to operate. Assisted by acoustic/tactile features, a user may find it very easy and convenient to slide an antenna-carrying assembly between a stowed state and a deployed state. The antenna-carrying assembly may be readily available with an electronic device whenever wireless communication is needed. A user may also find it very easy and convenient to reinstall the antenna-carrying assembly if the antenna-carrying assembly breaks away from a mating structure of the electronic device.
