Input to the touch panel display 4 can also be made, for example, with a finger. The display screen of the touch panel display 4 has a size of, for example, about 7 inches (a size that occupies more than half of the front surface area of the housing). Therefore, this electronic device 100 is not used by placing it on the palm like a portable information terminal called a palm size, but is used by holding the end of the casing with both hands or one hand. It is. In addition, the electronic device 100 can use the touch panel display 4 in either a portrait orientation (taken in the longitudinal direction of the Y axis) or a landscape orientation (taken in the longitudinal direction of the X axis).

  Here, an example is shown in which the electronic device 100 is equipped with a touch panel display 4 having a data input function as a display device. However, the present invention is not limited to this. For example, a data input unit such as a pointing device is provided separately, It is also possible to mount an LCD (Liquid crystal display) or the like that does not have an input function.

  The electronic device 100 also includes a wireless communication system for receiving mobile communication services, a wireless communication system for receiving public wireless LAN services, and a wireless communication system for performing wireless communication with peripheral devices. ing. As an antenna for a wireless communication system for receiving a mobile communication service, the electronic device 100 includes a cellular main antenna 1a for transmission / reception (Tx, Rx) and a cellular sub-antenna 1b for reception (Rx). Is done. In addition, as an antenna for a wireless communication system for receiving a public wireless LAN service and a wireless communication system for performing wireless communication with peripheral devices, the electronic device 100 includes Bluetooth (registered trademark) for transmission and reception. / WiFi antenna 2a (hereinafter referred to as BT / WiFi antenna 2a) and WiFi [2] antenna 2b for reception are mounted. Furthermore, the electronic device 100 has a GPS (Global positioning system) function and is equipped with a GPS antenna 3 for the GPS function.

  As described above, the electronic device 100 is a portable information terminal that is used by holding the end of the casing with both hands or one hand, and the touch panel display 4 can be used in either a portrait or landscape orientation. . In addition, as shown in FIG. 1, the electronic device 100 includes a touch panel display 4 (having a size in which the display screen occupies more than half the area of the front surface of the housing) disposed in the center of the front surface of the housing, and The housing has a thin board shape. Therefore, the cellular main antenna 1a, the cellular sub antenna 1b, the BT / WiFi antenna 2a, the WiFi [2] antenna 2b, and the GPS antenna 3 are inevitably the peripheral part of the touch panel display 4 and may be grasped by hand. It will be arranged at the end of a certain housing.

  Under such conditions, the electronic device 100 can be used in any direction, and can be held by one hand or both hands, that is, no matter which part of the casing is held, The communication system is provided with a mechanism for suppressing deterioration of antenna characteristics when held by the user so that each communication system can always perform wireless communication satisfactorily. This point will be described in detail below.

  As shown in FIG. 1, the electronic device 100 includes, firstly, two antennas, a cellular main antenna 1a and a cellular sub-antenna 1b, which are antennas for a wireless communication system for receiving a mobile communication service, and a public wireless Of the two antennas, a BT / WiFi antenna 2a and a WiFi [2] antenna 2b, which are antennas for a wireless communication system for receiving a LAN service and a wireless communication system for performing wireless communication with peripheral devices The at least one of each is arranged at the center of different sides of the two orthogonal sides of the casing.

  In addition, the electronic device 100 secondly, for each of the two wireless communication systems, at least one of the other antennas (other than the antenna arranged at the center of each side) is used as an antenna of another wireless communication system. Is placed on the side located in the center, and the other antenna is located in a region facing the side direction where the other antenna of the system is located in the center from the center of the side. .

  More specifically, among the two antennas, the cellular main antenna 1a and the cellular sub-antenna 1b, the cellular main antenna 1a is arranged at the center of the longitudinal side of the casing, and BT / WiFi. Of the two antennas, the antenna 2a and the WiFi [2] antenna 2b, the BT / WiFi antenna 2a is arranged at the center of the side orthogonal to the side where the cellular main antenna 1a is arranged at the center. Of the two antennas of each wireless communication system, the antenna arranged at the center of the side is preferably selected in preference to the antenna including the use for transmission (in addition to reception) over the antenna dedicated to reception.

  Secondly, the cellular sub-antenna 1b is disposed on the side where the BT / WiFi antenna 2a is disposed at the central portion on the side farther from the cellular main antenna 1a than the BT / WiFi antenna 2a, and WiFi [2]. The antenna 2b is arranged on the side farther from the BT / WiFi antenna 2a than the cellular main antenna 1a on the side where the cellular main antenna 1a is arranged at the center.

  Note that the GPS antenna 3 faces the WiFi [2] antenna 2b direction from the cellular main antenna 1a on the side where the cellular main antenna 1a is arranged in the center (the side in the longitudinal direction of the housing where space is easily secured). Place in position.

  The positional relationship between the cellular main antenna 1a and the cellular sub-antenna 1b, and the BT / WiFi antenna 2a and WiFi [2] antenna 2b can be interchanged as shown in FIG.

  Here, with reference to FIGS. 3 and 4 in addition to FIGS. 1 and 2, a basic concept of antenna arrangement in the electronic device 100 shown in FIGS. 1 and 2 will be described.

  FIG. 3 is a diagram for explaining a form in which the electronic device 100 is used with both hands. In FIG. 3, “a1” and “a2” indicate a case where the touch panel display 4 is used in a vertically long direction, and “b1” and “b2” indicate a case where the touch panel display 4 is used in a horizontally long direction. Yes.

  As shown in FIG. 3, when using the electronic device 100 with both hands, it is considered that the two opposite sides of the housing are gripped regardless of whether the touch panel display 4 is used in a portrait or landscape orientation. . Further, it is presumed that the lower end portion is more likely to be gripped than the center portion of each side. Therefore, by arranging at least one antenna of each wireless communication system in the center of the side, it is possible to increase the probability of maintaining the antenna in a state not covered with hands, By placing two antennas on two orthogonal sides, at least one antenna is not covered with a hand even when the central part (presumably unlikely) is gripped Can be maintained.

  The above-mentioned “of the two antennas of each wireless communication system, the antenna arranged at the center of the side is selected in preference to the antenna including the use for transmission (in addition to reception) over the antenna dedicated to reception. The reason “preferably” is based on the assumption that the lower end portion is more likely to be gripped than the center portion of each side described here.

  FIG. 4 is a diagram for explaining a form in which the electronic apparatus 100 is used with one hand. In FIG. 4, “c1” and “c2” indicate the case where the touch panel display 4 is used in the vertically long direction, and “d1” and “d2” indicate the case where the touch panel display 4 is used in the horizontally long direction. Yes.

  As shown in FIG. 4, when the electronic apparatus 100 is used by being held with one hand, the two places at the end of the casing are not simultaneously covered with the hand. Therefore, according to the antenna arrangement of the electronic apparatus 100 in which the two antennas of each wireless communication system are arranged on two orthogonal sides, at least one antenna is maintained in a state that is not covered with a hand.

  FIG. 5 and FIG. 6 are diagrams showing examples of general antenna arrangements in an electronic device equipped with two wireless communication systems.

  In the electronic device shown in FIG. 5, the antennas (1, 2a) of the two wireless communication systems are arranged on different sides of the two opposite sides of the casing. In the electronic device shown in FIG. 6, the antennas (1, 2) of the two wireless communication systems are arranged on the same side of the casing. Depending on how these two electronic devices are held, the antenna of any wireless communication system may be covered with a hand, leading to deterioration of antenna characteristics.

  On the other hand, as shown in FIG. 1 or FIG. 2, (1) at least one antenna of each radio communication system is arranged at the center of the side, and (2) two antennas of each radio communication system are orthogonal 2 The electronic device 100 adopting the antenna arrangement such as being arranged on the side does not cause deterioration of the antenna characteristics for any wireless communication system.

  As described above, the electronic device 100 realizes suppressing the deterioration of the antenna characteristics when held by the user.

  Here, the cellular sub-antenna 1b is disposed on a side farther from the cellular main antenna 1a than the BT / WiFi antenna 2a on the side where the BT / WiFi antenna 2a is disposed at the center, and WiFi [2]. The example which has arrange | positioned the antenna 2b in the side far from the BT / WiFi antenna 2a rather than the said cellular main antenna 1a of the edge | side where the cellular main antenna 1a is arrange | positioned in the center part was shown. This is intended to secure the distance between the cellular main antenna 1a and the cellular sub-antenna 1b, and the distance between the BT / WiFi antenna 2a and the WiFi [2] antenna 2b (antenna by separating the distances). Inter-isolation).

  On the other hand, the antenna characteristics of each antenna depend on, for example, how the ground pattern is formed. Therefore, for example, by adjusting the shape of this ground pattern, as shown in FIGS. 7 and 8, the cellular sub-antenna 1b and the WiFi [2] antenna 2b are replaced with the (BT / WiFi antenna 2a and the cellular main antenna 1a). It is also possible to implement an antenna aggregation where the cellular main antenna 1a and the BT / WiFi antenna 2a are arranged closer to each other (as a base point).

  That is, the electronic device 100 is essentially based on the point that two antennas of each wireless communication system are arranged on two orthogonal sides, and at least one antenna of each wireless communication system is arranged at the center of each side. In addition, the antenna other than the antenna disposed in the central portion is not limited to being disposed so as to be separated from the antenna disposed in the central portion.

  And this electronic device 100 arrange | positions the cellular main antenna 1a for transmission / reception in the edge | side facing the edge | side where this charging connector 5 is arrange | positioned. In other words, the side where the cellular main antenna 1a is arranged is the side facing the side where the charging connector 5 is arranged.

  Consider a case where wireless communication is performed in a state where the electronic device 100 is connected to a charger or an expansion unit. By disposing the cellular main antenna 1a on the side opposite to the side where the charging connector 5 is disposed, the deterioration of the antenna characteristics of the cellular main antenna 1a when the electronic device 100 is connected to the charger or the extension unit is suppressed. be able to.

  Also, as shown in FIG. 10, the positional relationship between cellular main antenna 1a and cellular sub-antenna 1b, and BT / WiFi antenna 2a and WiFi [2] antenna 2b can be interchanged. For example, when a wireless communication system using the cellular main antenna 1a is given priority over a wireless communication system using the BT / WiFi antenna 2a, the antenna arrangement shown in FIG. 9 is adopted, while the wireless communication using the BT / WiFi antenna 2a is used. When the system is prioritized over the wireless communication system using the cellular main antenna 1a, the antenna arrangement shown in FIG. 10 may be adopted.

(Third embodiment)
Next, a third embodiment will be described.

  FIG. 11 is a diagram illustrating an appearance and an antenna arrangement of the electronic device 100 according to the present embodiment.

  As shown in FIG. 11, the electronic device 100 is provided with operation hard keys 7 on the periphery of the touch panel display 4 on the front surface of the housing. In the electronic device 100, the antennas of the cellular main antenna 1a, the cellular sub antenna 1b, the BT / WiFi antenna 2a, and the WiFi [2] antenna 2b are arranged on different sides from the side on which the hard key 7 is arranged. To do. In other words, two sides orthogonal to the side where the cellular main antenna 1a and the WiFi [2] antenna 2b are arranged and the side where the BT / WiFi antenna 2a and the cellular sub antenna 1b are arranged are sides where the hard key 7 is arranged. Different sides.

  Consider a case where the hard key 7 is operated during execution of wireless communication. By disposing each antenna on a side different from the side on which the hard key 7 is disposed, it is possible to suppress deterioration of antenna characteristics of each antenna when the hard key 7 is operated during wireless communication.

  Also, as shown in FIG. 12, the positional relationship between cellular main antenna 1a and cellular sub-antenna 1b and BT / WiFi antenna 2a and WiFi [2] antenna 2b can be interchanged.

(Fourth embodiment)
Next, a fourth embodiment will be described.

  FIG. 13 is a diagram illustrating an appearance and an antenna arrangement of the electronic device 100 according to the present embodiment.

  In the second embodiment described above, the antenna arrangement example in the case where the charging connector 5 for inputting the power for charging the battery 6 is provided on the side surface of the housing has been described. On the other hand, the electronic device 100 incorporates a wireless charging antenna 9 for inputting power for charging the battery 6 in an electrically non-contact state. The electronic device 100 places the wireless charging antenna 9 on the back side of the circuit board 8 when the wireless charging antenna 9 is built in the housing. FIG. 14 is a partial cross-sectional view for illustrating an example of placing the wireless charging antenna 9 on the circuit board 8.

  As shown in FIG. 14, the wireless charging antenna 9 is placed on the side of the circuit board 8 facing the direction of the touch panel display 4. By disposing the wireless charging antenna 9 on the back side where the circuit density is generally low compared to the front side, the heat generation of the battery 6 is reduced even a little. Thereby, this electronic device 100 further realizes suppressing the characteristic deterioration of the battery 6 (prolonging the life).

(Fifth embodiment)
Next, a fifth embodiment will be described.

  FIG. 15 is a diagram illustrating an appearance and an antenna arrangement of the electronic device 100 according to the present embodiment.

  In the first to fourth embodiments described above, the two antennas of each radio communication system are arranged on two orthogonal sides, and at least one antenna of each radio communication system is arranged on the center of each side. An example was explained.

  On the other hand, portable electronic devices such as the electronic device 100 have recently been increasingly equipped with cameras for taking still images and moving images. In many cases, the camera is arranged at the center of one side of the casing, which is the peripheral part of the display screen. Also, the side on which the camera is placed is also a side suitable for placing an antenna (away from the user's body). Since the camera position is given priority between the camera position and the antenna position, the antenna cannot be arranged at the center of the side. That is, as in the first to fourth embodiments described above, it is not possible to arrange at least one antenna of each wireless communication system in the center of each side.

  In such a case, the electronic device 100 includes two antennas, a cellular main antenna 1a and a cellular sub antenna 1b, and a BT / WiFi antenna on two sides, a side where the camera 10 is disposed and a side orthogonal to the side. Two antennas 2a and WiFi [2] antenna 2b are respectively arranged, and one of these two sets of antennas is arranged at the center of the side orthogonal to the side on which camera 10 is arranged. In the example of FIG. 15, the cellular main antenna 1 a is arranged at the center of the side orthogonal to the side where the camera 10 is arranged. Further, the BT / WiFi antenna 2 a is a side where the camera 10 is arranged, and is arranged in the vicinity of the camera 10. The positional relationship between cellular main antenna 1a and cellular sub-antenna 1b and BT / WiFi antenna 2a and WiFi [2] antenna 2b can be interchanged as shown in FIG.

  In the present electronic device 100, only one of the antennas of the two wireless communication systems is arranged in the central part of the side (it is assumed that the possibility of being gripped with a hand is low). Is arranged on two orthogonal sides, so that at least one antenna can be maintained in a state not covered by a hand. Therefore, the electronic apparatus 100 can also suppress deterioration of antenna characteristics when held by the user.

(Sixth embodiment)
Next, a sixth embodiment will be described.

  In the above-described fourth embodiment, the case where the battery 6 is charged using the wireless charging antenna 9 capable of inputting electric power in a non-contact state is illustrated. Charging of the battery 6 using the wireless charging antenna 9 is performed by setting it in an expansion unit with a charging function called a cradle, for example.

  Consider a case where the electronic device 100 is used in a state where it is set in an expansion unit. As described above, the electronic device 100 can use the touch panel display 4 in either a portrait or landscape orientation. Further, since the wireless charging antenna 9 can input electric power in a non-contact state, in order to take advantage of this advantage, for example, as shown in FIG. It is preferable to configure the expansion unit 200 so that it can be performed in any direction (“e1” in FIG. 17) and landscape (“e2” in FIG. 17).

  Therefore, as shown in FIG. 18 or FIG. 19, the electronic device 100 according to the present embodiment has the wireless charging antenna 9 at a corner facing a corner where two orthogonal sides where the two antennas of each wireless communication system are arranged intersect. Deploy. FIG. 18 shows an example in which the wireless charging antenna 9 is formed in a rectangular shape, and FIG. 19 shows an example in which the wireless charging antenna 9 is formed in an L shape. By forming the wireless charging antenna 9 in a rectangular or L-shape, either side of the wireless charging antenna 9 is along any of the two sides that intersect at a corner where the wireless charging antenna 9 is disposed. Therefore, the battery 6 can be charged via the wireless charging antenna 9 even if the electronic device 100 is set in the expansion unit 200 with either of the two sides intersecting at one corner where the wireless charging antenna 9 is disposed as the lower end.

  In addition, by disposing the wireless charging antenna 9 at this position (a corner opposite to a corner where two orthogonal sides where the two antennas of each wireless communication system are disposed), the electronic device 100 can be placed either vertically or horizontally. Even if the extension unit 200 is set, the antenna arranged at the center of the side is not covered with the extension unit 200.

  In the above-described fourth embodiment, the example in which the wireless charging antenna 9 is placed on the back side of the circuit board 8 has been described. However, the wireless charging antenna 9 is not limited to the circuit board 8, and the wireless charging antenna 9 is, for example, a housing. It may be arranged on the inner wall on the back side and connected to the circuit board 8 by a harness, a coaxial cable or the like.

  As described above, the electronic device 100 can realize the arrangement of the wireless charging antenna 9 that can be charged regardless of the orientation, and can be attached to the expansion unit 200 in addition to the case where the electronic device 100 is held by the user. It is possible to suppress deterioration of antenna characteristics in the set state.
