The input / output device is an audio input device (for example, a microphone), an audio output device (for example, a loudspeaker), a display, or the like.

  The device 12 and the electronic components that provide the radio frequency circuit 14 and circuit 16 may be interconnected via a ground member 18 (eg, a printed wiring board). The ground member 18 can be used as a ground plane of the device 12 by using one or more layers of the printed wiring board 18. In other embodiments, another conductive portion of the electronic device 10 (eg, a battery cover or an interior chassis of the housing 20) may be used as the ground member 18 of the device 12.

  The device 12 will be described with reference to several embodiments in the following paragraphs.

  FIG. 2 shows a schematic diagram of an apparatus 121 according to various embodiments. The device 121 includes a ground member 18, a conductive cover part 24, a feeding point 26, and a radiation part 28.

  The conductive cover part 24 forms at least a part of the housing 20 and can have any shape. For example, the conductive cover portion 24 forms the side surface of the device 10 and may be U-shaped when viewed from a plane (as shown in FIG. 3). In other embodiments, the conductive cover portion 24 forms the back side of the device 10 and may be rectangular. In another embodiment, the conductive cover portion 24 may be attached to the interior of the insulating housing portion and may have a meandering shape.

  The housing 20 may include a plurality of conductive cover portions 24. These conductive cover portions may or may not be galvanically connected to each other. The conductive cover portion 24 may include any conductive member, and may include, for example, one or more metals and / or one or more conductive polymers.

  The conductive cover portion 24 may define the interior surface 30 of the device 121 and the device 10. Depending on the embodiment, one or more layers of other members (for example, a dipole member, an insulating member, and a member that increases the structural strength of the housing 20) may be provided on the interior surface 30 of the conductive cover portion 24. . In another embodiment, a configuration in which a layer of another member is not added to the interior surface 30 may be employed.

  The conductive cover portion 24 can also define the exterior surface 32 of the device 121 and the device 10. As a result, the conductive cover portion 24 can form at least a part of the exterior visible surface of the device 121 and the device 10. In some embodiments, one or more layers of other insulating members (eg, a protective plastic coating or cover) may be provided on the exterior surface 32 of the conductive cover portion 24. In another embodiment, a configuration in which a layer of another member is not added to the exterior surface 32 may be employed.

  The conductive cover portion 24 is coupled to the ground member 18 through the ground point 34. In FIG. 2, the ground point 34 is connected to the first end 36 of the conductive cover portion 24, but may be connected at an arbitrary position of the conductive cover portion 24 in other embodiments. Since the grounding member 18 is located in the interior surface of the housing 20, it is located in the interior surface 30 of the conductive cover portion 24. In other embodiments, the conductive cover portion 24 may cover the ground member 18.

  Radiator 28 is coupled to feed point 26 so that it can provide signals to and / or receive signals from radio frequency circuit 14. The transmission line 37 (coaxial cable or the like) is configured to interconnect the feeding point 26 and the radio frequency circuit 14 so that a signal can be transmitted between the feeding point 26 and the radio frequency circuit 14. The transmission line 37 is provided on at least a part of the conductive cover part 24 (as shown in FIG. 2) and may be physically coupled.

  The radiating portion 28 is also coupled to the second end portion 38 of the conductive cover portion 24 and extends from the conductive cover portion 24 to the end portion 40. In some embodiments, the radiating portion 28 may not be coupled to the second end portion 38 but may be coupled between the first end portion 36 and the second end portion 38 of the conductive cover portion 24. Alternatively, it may be coupled to a conductive member connected to the conductive cover portion 24 (as shown in FIG. 5). The radiating portion 28 has any suitable shape, and may be, for example, a monopole or a folded monopole. In some embodiments, the radiating portion 28 may be planar, and in other embodiments, non-planar.

  The radiating portion 28 is configured to be electromagnetically coupled to the conductive cover portion 24 (that is, the conductive cover portion 24 may be parasitically coupled to the radiating portion 28). The conductive cover portion 24 and the radiating portion 28 have a predetermined electrical length configured to resonate in the first operating frequency band (the first operating frequency band is one of the operating frequency bands described in the previous paragraph). Yes, but not limited to those bands). The electrical lengths of the conductive cover portion 24 and the radiating portion 28 include the physical length of the conductive cover portion 24 and the radiating portion 28 measured between the ground point 34 and the end portion 40 of the radiating portion 28, and the reactance therebetween. Components (such as one or more capacitors and / or one or more inductors) are included. The electrical lengths of the conductive cover part 24 and the radiating part 28 may include the length from the feeding point 26 to the point farthest from the ground plane 18.

  FIG. 3 shows a plan view of another apparatus 122 according to various embodiments. The device 122 is similar to the device 121 shown in FIG. 2, and its configuration is also similar. For this reason, the same reference numbers are used.

  The device 122 includes a first conductive cover portion 24 and a second conductive cover portion 42, and is different from the device 121 in this respect. The first conductive cover portion 24 is U-shaped when viewed from above (the first end 36 and the second end 38 are both ends of “U”), and forms the side surface of the device 122. The second conductive cover portion 42 is also U-shaped in plan view (having a first end 44 and a second end 46 that are opposite ends of “U”) and forms another side of the device 122. . The second conductive cover portion 42 defines an interior surface 45 and an exterior surface 47 of the apparatus 122 and the electronic device 10.

  The first end 36 of the first conductive cover portion 24 and the first end 44 of the second conductive cover portion 42 define a gap 48 therebetween. In the gap 48, electronic components (eg, universal serial bus (USB) connectors, audio connectors, etc.) can be advantageously placed.

  In another embodiment, there is no gap 48, and the first end 36 of the first conductive cover portion 24 and the first end 44 of the second conductive cover portion 42 have a single conductive cover portion 24, 42. It can also be formed. In these other embodiments, the electronic component can be disposed at an arbitrary position along the length of the single conductive cover portion in the opening formed in the single conductive cover portion 24 or 42.

  The second end 38 of the first conductive cover portion 24 and the second end 46 of the second conductive cover portion 42 also define a gap 50 therebetween. Even in the gap 50, electronic components can be arranged. The gaps 48 and 50 are defined at both lateral ends of the electronic device 10. As a result, the longitudinal end of the electronic device 10 can be advantageously formed by a continuous conductive member (such as a metal). Such a continuous conductive member is visually attractive for the end user of the device 10. The gaps 48 and 50 can be covered by doors or other covers that conceal and protect the electronic components there. If a conductive (eg metal) door or other cover is used, it may be physically separated from the first end 36/44 (ie, the conductive door or other cover is Electrically floating).

  The ground member 18 is disposed in the interior surfaces 30 and 45 of the first and second conductive cover portions 24 and 42, respectively. The grounding member 18 is separated from the second ends 38 and 46 of the first and second conductive cover portions 24 and 42 (that is, the lower cross section of the conductive cover portions 24 and 42), and the first member 18 is interposed therebetween. The opening 52 is defined.

  The grounding member 18 is spaced apart from the first ends 36 and 44 of the first and second conductive cover portions 24 and 42 (that is, the upper cross section of the conductive cover portions 24 and 42), and another ground member is interposed therebetween. An opening 53 is defined.

  The grounding member 18 is coupled to the longitudinal section of the conductive cover portions 24 and 42, thereby grounding the conductive cover portions 24 and 42 at at least one point. The longitudinal sections of the first conductive cover portion 24 and the ground member 18 define a second opening 54 (a groove in this embodiment) therebetween. Depending on the embodiment, the second opening 54 may be formed by removing a part of the grounding member 18. Alternatively or in addition, the second opening 54 may be formed by changing the interior surface 30 of the first conductive cover portion 24. For example, the second opening 54 may be formed by making a part of the first conductive cover part 24 thinner than the remaining part of the first conductive cover part 24. The proximity end of the second opening 54 provides a ground point 34 for the first conductive cover 24. The size of the second opening 54 may be selected during creation of the device 122 so that the first conductive cover portion 24 has a desired electrical length.

  The longitudinal sections of the second conductive cover portion 42 and the ground member 18 define a third opening 56 (also a groove in this embodiment) therebetween. Depending on the embodiment, the third opening 56 may be formed by removing a part of the grounding member 18. The proximal end of the third opening 56 provides a ground point 58 for the second conductive cover portion 42. The size of the third opening 56 may be selected during creation of the device 122 such that the third conductive cover portion 42 has a desired electrical length.

  The radiating portion 28 is coupled to the second end portion 38 of the first conductive cover portion 24 via the feeding point 26. The radiating portion 28 extends from the feeding point 26 and extends into a first opening 52 defined between the conductive cover portions 24 and 42 and the ground member 18. Thus, the end portion 40 of the radiating portion 28 is disposed adjacent to the ground member 18. In other embodiments, the end 40 of the radiating portion 28 may be located away from the ground member 18 (ie, they are not adjacent to each other). As a result, when the device 122 is viewed in plan, the radiating portion 28 is in a positional relationship that does not cover the first conductive cover portion 24. In another embodiment, when the device 122 is viewed in plan, the radiating portion 28 may be in a positional relationship covering at least a part of the first conductive cover portion 24. In some embodiments, the radiating portion 28 may be on the same plane as the ground member 18. In other embodiments, the radiating portion 28 may be at least partially on a different plane from the ground member 18 and at least partially cover the ground member 18.

  FIG. 4 shows a graph of return loss (dB) versus frequency for the device 122 shown in FIG. This graph has an X axis 60 representing frequency and a Y axis 62 representing reflection loss (S parameter, S11).

  Also shown in the graph is a curve 64 representing how the reflection loss of device 122 varies with operating frequency. Curve 64 represents a first minimum 66, a second minimum 68, a third minimum 70, a fourth minimum 72, a fifth minimum 74, a sixth minimum 76, and a seventh minimum representing the resonance mode of device 122. It has a minimum 78.

  The first minimum 66 is a quarter crossing the electrical length of the radiating portion 28 and the first conductive cover portion 24 (that is, the electrical length between the end 40 of the radiating portion 28 and the ground point 34). 1/4) Corresponds to wavelength resonance mode. The first minimum 66 has a reflection loss of -7 dB at a frequency of 0.8 GHz.

  The second minimum 66 corresponds to a half (1/2) wavelength resonance mode that traverses the electrical length of the radiating portion 28 and the first conductive cover portion 24. The 1/2 wavelength resonance mode of the radiating portion 28 and the first conductive cover portion 24 is coupled to the second conductive cover portion 42, specifically, the electrical length of the second conductive cover portion 42 (ie, the second conductive cover portion 42). Coupled to a quarter-wave resonant mode that traverses the electrical length between the end 46 of the circuit and the ground point 58). As a result, the second conductive cover portion 42 advantageously contributes to the radiation pattern of the device 122 and also contributes to the second minimum 68. The second minimum 68 has a reflection loss of -20 dB at a frequency of 1.5 GHz.

  The third minimum 70 corresponds to a three-quarter (3/4) wavelength resonance mode that traverses the electrical length of the radiating portion 28 and the first conductive cover portion 24. The third minimum 70 has a frequency of 1.9 GHz and a reflection loss of -30 dB.

  The fourth minimum 72 corresponds to a 1 and 1/4 (1 + 1/4) wavelength resonance mode that traverses the electrical length of the radiating portion 28 and the first conductive cover portion 24. The fourth minimum 72 has a reflection loss of −12 dB at a frequency of 3.4 GHz.

  The fifth minimum 74 corresponds to a 1/3/4 wavelength resonance mode that traverses the electrical length of the radiating portion 28 and the first conductive cover portion 24. The fifth minimum 74 has a reflection loss of -16 dB at a frequency of 3.4 GHz.

  The sixth minimum 76 corresponds to a 2 and 1/4 (2 + 1/4) wavelength resonance mode that traverses the electrical length of the radiating portion 28 and the first conductive cover portion 24. The sixth minimum 76 has a reflection loss of -2 dB at a frequency of 5.5 GHz.

  The seventh minimum 78 corresponds to a 2 and 3/4 (2 + 3/4) wavelength resonance mode that traverses the electrical length of the radiating portion 28 and the first conductive cover portion 24. The seventh minimum 78 has a reflection loss of -19 dB at a frequency of 6.5 GHz.

  FIG. 5 shows a plan view of yet another apparatus 123 according to various embodiments. The device 123 is similar to the device 122 shown in FIG. 3, and its configuration is also similar. For this reason, the same reference numbers are used.

  The device 123 is different from the device 122 in that the radiating portion 28 is coupled to the first conductive cover portion 24 via the conductive member 80. The conductive member 80 extends from the second end portion 38 of the first conductive cover portion 24 into the opening 52 and to the end portion 82. The feeding point 26 is located at the end 82 of the conductive member 80, and the radiating part 28 is coupled to the feeding point 26. Depending on the embodiment, the feeding point 26 may not be disposed at the end portion 82 of the conductive member 80 but may be disposed along the length direction of the conductive member 80.

  The conductive member 80 includes the length of the conductive member 80 and / or the conductive member 80 to provide a desired electrical length for the radiating portion 28 and the conductive member 80, the first conductive cover portion 24, and combinations thereof. There is an advantage that the position of the feeding point 26 can be selected.

  In addition, the conductive member 80 also has the advantage that the impedance of the device can be selected to better match the target characteristic impedance (Zo). The location of feed point 26 can affect the impedance matching achieved over one or more bands in which the device operates. The position of the feed point 26 can be varied along the length and / or width of the conductive member 80 and / or conductive cover portion 24 until the desired impedance matching is achieved, and the conductive member 80 suitable for the device. A point in (or conductive cover portion 24) is selected.

  The devices 121, 122, and 123 have an advantage that they are relatively unaffected by an external object (such as a user's hand) that attempts to contact the conductive cover portions 24 and. This is because the radiating portion 28 extends to the inside of the apparatus and cannot contact an external object that degrades the performance of the radiating portion 28.

  In addition, the second conductive cover portion 42 is parasitically coupled to the radiating portion 28 and the first conductive cover portion 24 in the devices 121, 122, and 123, and at least partially provides the second minimum 68 described in the previous paragraph. There is also an advantage. Furthermore, the second conductive cover part 42 can also widen the resonance mode band of the radiating part 28 and the first conductive cover part 24.

  The devices 121, 122, 123 also have the advantage that they can resonate in a plurality of operating frequency bands. Such a device may be configured to operate in an operating frequency band that allows voice communication (such as CDMA) in addition to the LTE frequency band. As a result, the devices 121 and 122 can simultaneously provide both voice (CDMA) and data (LTE) performance (referred to as SV-LTE).

  FIG. 6 shows a top view of yet another apparatus 124 according to various embodiments. The device 124 is similar to the device 122 shown in FIG. 3, and its configuration is also similar. For this reason, the same reference numbers are used.

  The device 124 further comprises a second feed point 84 and a second radiating portion 86, which differs from the device 122 in this respect. The second feeding point 84 is disposed at the second end 46 of the second conductive cover part 42. In other embodiments, the second feeding point 84 may be disposed at any other position of the second conductive cover portion 42. The second feed point 84 is coupled to the radio frequency circuit 14 so that it can provide a signal to the radio frequency circuit 14 and / or receive a signal from the radio frequency circuit 14. For example, a transmission line (such as a coaxial cable) is configured to interconnect the second feeding point 84 and the radio frequency circuit 14 so that signals can be transmitted between the second feeding point 84 and the radio frequency circuit 14. . The transmission line may be provided in at least a part of the second conductive cover portion.

  The second radiating portion 86 is a folded monopole and is coupled to the second conductive cover portion 42 via the second feeding point 84.
