Eyeglass-type multimedia terminals that are handled as main content are attracting attention.

  On the other hand, the human body is a lossy medium, and it is known that the influence of a nearby human body on the antenna affects its input impedance and radiation characteristics.

Proposed through-hole type Yagi / Uda antennas have been proposed (see, for example, Non-Patent Document 1 and Non-Patent Document 2). In the field of mobile terminals, content that will require high-speed and large-capacity communication in the future is moving image information, and it is required to use the millimeter wave band to cope with this.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of an eyeglass-type communication device according to the present invention will be described with reference to the drawings. An eyeglass-type communication device 1 according to the present invention has an eyeglass-type shape and is used by being mounted on a user's head. As shown in FIG. 1, a pair of temples 2a, 2b, a frame 3 to which one end side of the pair of temples 2a and 2b is connected, an endfire type antenna 4 arranged on one temple 2a, and a broadside type antenna 5 arranged on the frame 3; An image display unit 6 for displaying moving images and the like, a line-of-sight detection unit 7 for detecting the user's line-of-sight direction, and antennas 4 and 5 are positioned in front of the left and right eyes of the user when worn. And a control unit 8 for performing control of each part such as control of the beam direction of the antenna 4 and the antenna 5 based on the detection result of the line-of-sight direction detected by the line-of-sight detection unit 7.

  The pair of temples 2a and 2b are arranged so as to sandwich the user's head from the left and right sides when worn, and one end side is folded with respect to the frame 3 via a hinge (connecting member) 9, respectively. It is connected freely, and a modern 21 is formed on the other end side to be put on the user's ear when worn. The modern 21 may be formed of a covering member such as a plastic resin so as to improve the user's comfort.

  The frame 3 is a frame for holding the image display unit 6 disposed in front of the left and right eyes of the user, and is provided so as to cover the outer periphery of the image display unit 6. A bridge for connecting the left and right image display units 6 is provided at the center of the frame 3. Note that the frame 3 is not necessarily provided so as to cover the entire outer periphery of the image display unit 6, and the image display unit 6 such as one that holds the image display unit 6 so as to cover the upper or lower half. As long as it can be held.

  The image display unit 6 is installed so as to occupy a part or the whole of the spectacle lens surface, and displays a moving image or the like based on a video signal or the like acquired by wireless communication with the antenna 4 or the antenna 5. For example, a liquid crystal display (Liquid Crystal Display) or a retinal scanning display that projects an image on the user's retina can be used.

  The antenna 4 is for receiving a video signal or the like supplied from the base station 10 by performing radio communication with a base station 10 or the like provided outside, for example, and is disposed on the temple 2a. Yes. As the antenna 4, for example, as shown in FIG. 3, a ground plate 41 made of a flat conductor, a dielectric substrate 42 stacked on the ground plate 41, and a dielectric substrate 42 are formed. A through-hole type Yagi-Uda antenna is used in which a through-hole 43 is provided with a radiating element 44 or the like in which a capacitor hat having a spread of conductive foil is provided to change the equivalent element length.

  This antenna 4 is an endfire type antenna that emits radiation in a direction parallel to the longitudinal direction of the dielectric substrate 42, and is embedded on the outer surface side of the temple 2a as shown in FIG. Since the base plate 41 is attached to the outer surface of the temple 2a so that the longitudinal direction of the dielectric substrate 42 is along the temple 2a, the directivity is set substantially in the same direction as the direction of the temple 2a. Will have. Therefore, when the user wears the eyeglass-type communication device 1 on the head, as shown in FIGS. 1 and 2, the user has directivity in the front direction of the frame 3. Thereby, the user can automatically link the beam directing direction of the antenna 4 by moving the head while wearing the glasses-type communication device 1 on the head.

  Normally, the viewing angle that a human can view without moving the viewpoint is about 10 degrees, and in the case of an angle range larger than that, a supplementary operation is performed by rotating the eyeball or the head. Further, the angle range in which the viewpoint is moved by the rotation of the eyeball without rotating the head without a sense of incongruity is about 30 degrees, and in an angle region exceeding this, a supplementary operation accompanied by the rotation of the head is performed. Therefore, if the antenna 4 of the eyeglass-type communication device 1 to be worn on the user's head is an antenna having a half-value angle of about 30 degrees, it is based on the detection result of the gaze direction detected by the gaze detection unit 7 described later. Even if the beam direction of the antenna 4 is not scanned, by moving the head so as to face the direction of the base station 10 that supplies the video signal or the like that the user wants to acquire, the base station 10 and the base station 10 in the directivity direction are wirelessly connected. Communication can be performed and a video signal or the like to be acquired can be received. Further, such an antenna 4 having a half-value angle of about 30 degrees has a directivity gain of about 16 dB. Therefore, when the line-of-sight detection unit 7 is not provided, it is preferable to use an endfire type antenna having a half-value angle of about 25 to 35 degrees and a directivity gain of about 14 to 16 dB.

  As the antenna 4 that has such a half-value angle and directivity gain and can be disposed on the temple 2a having a general structure, for example, as shown in FIG. A length Lg of 39 mm, a width Wd of the dielectric substrate 42 of 1.8 mm, and a length Ld of the dielectric substrate 42 of 39 mm which is the same as the ground plane length Lg can be used. In this antenna 4, the operating frequency is designed as a 60 GHz band, and the thickness of the dielectric band substrate 41 is 0.16 mm, the relative dielectric constant is 2.2, and the dielectric loss tangent is 0.001. Further, when the width Wd of the dielectric substrate 42 is set to 1.8 mm, a portion of the ground plane 41 excluding the central portion where the dielectric substrate 42 is provided is exposed. In addition, it is not desirable to provide a gap between the main plate 41 and the outer surface of the temple 2a from the viewpoint of mechanical strength. For this reason, although not shown in detail, by forming a plurality of substantially square air holes on both sides of the dielectric substrate 42 in the width direction, the equivalent relative permittivity is lowered while maintaining the mechanical strength. Therefore, it may be configured to satisfy the electrical characteristics.

  4 and 5 are graphs showing the directivity and directivity gain results of the respective antennas 4 designed as described above. In such an antenna 4, as shown in FIG. 4, the beam is tilted by about 10 degrees. On the other hand, the temple 2a (2b) of general glasses has an opening angle θ of about 10 degrees in order to match the shape of the human head as shown in FIG. Therefore, in this antenna 4, the beam tilt angle θ ′ and the opening angle θ of the temple 2 a are substantially coincident with each other, so that the beam is corrected to face the front direction of the frame 3. Further, since the antenna 4 is formed by providing the dielectric substrate 42 on the ground plane 41, it is possible to reduce the influence of the human body to be worn and the influence of the metal used for the temple 2a. Further, as shown in FIG. 2, one end side of the base plate 41 is provided so as to protrude to the front side from the hinge 9 that foldably connects the temple 2a and the frame 3, so that the connecting member is made of metal. Even if it is made of a material, it can be made less susceptible to the influence. The size and the like of the antenna 4 shown here are merely examples, and are not particularly limited to this, and can be appropriately designed according to the size and shape of the temple 2a. Moreover, although the antenna 4 has shown the example arrange | positioned at the temple 2a located in the right side of a user's head in this embodiment, the temple 2b located in the temple 2a and the right side of a user's head is shown. It is also possible to arrange them only in both of them or in the temple 2b. When the antennas 4 are arranged on both the temple 2a and the temple 2b, the reliability of wireless communication can be improved, the communication capacity can be increased, and the transmission speed can be improved.

  Similar to the antenna 4, the antenna 5 is for receiving a video signal or the like supplied from the base station 10 by performing radio communication with a base station 10 or the like provided outside by radio waves. As shown in FIG. 4, the antenna is a so-called broadside antenna that is disposed on the outer peripheral surface of the upper portion of the frame 3 located in front of the user's left eye and has directivity in the front direction of the frame 3. As this antenna 5, for example, as shown in FIG. 6, a Yagi / Uda antenna formed horizontally on a dielectric substrate 51 is used.

In this antenna 5, in order to realize the reduction of the radiating element and the balance / unbalance conversion unit and the reduction in the axial direction so as to be arranged with a thickness of about several millimeters of the general frame 3, The substrate 51 has a thickness of 0.1 mm, a relative dielectric constant ε _{γ of} 2.2, and a dielectric loss tangent tan δ of 0.009 to form a folded radiating element using through holes. The hatched portion 52 in FIG. 6 is a ground plane, and the unhatched portion is constituted by a dielectric substrate 51. Reference numeral 53 denotes a through hole. As shown in FIG. 6, the dimensions of the antenna 5 are a1 = 0.22 mm, a2 = 1.14 mm, a3 = 1.48 mm, a4 = 0.1 mm, a5 = 1.11 mm, a6 = 1.1 mm, a7 = 0.1 mm, a8 = 1.8 mm, b1 = 2.5 mm, b2 = 0.69 mm, b3 = 1.14 mm, b4 = 0.69 mm, b5 = 0.3 mm, b6 = 0.1 mm, b7 = It is formed to 1.11 mm. In the antenna 5 having such a folded structure, a reduction of about 20% can be realized as compared with the case where the folded structure is not used. Further, the maximum operating gain of the antenna 5 is 8.4 dB. By arranging eight antennas in an area of 20 to 35 mm (4 to 7 wavelengths) in the broadside direction, the directivity gain becomes about 15 dB. Note that the dimensions and the like of the antenna 5 shown here are examples, and are not particularly limited, and can be appropriately designed according to the size and shape of the frame 3. When the antennas 5 are arranged, parallel and series feeding can be applied as feeding methods. Here, the conductor width and the primary line and the secondary line of the primary line (side to which the feed line is connected) and the secondary line (side to which the feed line is not connected), which are constituent elements of the radiating element having the folded structure of each single antenna. It is possible to adjust the input impedance of each single antenna by adjusting the interval of the next line. Thereby, it is possible to control the power distribution ratio to each arrayed antenna. If necessary, a partially folded radiating element having a structure in which only a part of the radiating element is folded may be used as the folded structure.

  Further, in the eyeglass-type communication device 1 according to the present embodiment, an example in which the antenna 5 is disposed on the upper part of the frame 3 as illustrated in FIG. 1 has been described, but the position where the antenna 5 is disposed is However, the present invention is not limited to this, and it may be arranged on the frame 3 so as to have directivity in the front direction of the frame 3. For example, it may be arranged on the outer peripheral surface of the lower part of the frame 3. In the eyeglass-type communication device 1 according to the present embodiment, by providing both the endfire antenna 4 and the broadside antenna 5, the reliability of wireless communication is improved and the communication capacity is improved. However, the present invention is not limited to this, and only one of the antenna 4 and the antenna 5 may be provided.

  The line-of-sight detection unit 7 is for detecting the line-of-sight direction of the user wearing the glasses-type communication device 1. In the eyeglass-type communication device 1, as shown in FIG. 1, the line-of-sight detection unit 7 is attached to the upper part of the frame 3 positioned in front of the right eye so as to detect the direction of the user's right eye. . As the line-of-sight detection unit 7, for example, a method of irradiating the eyes with infrared light from an infrared light emitting diode or the like, and detecting the reflected infrared light with an image sensor or the like to detect the direction of the line of sight, laser light is used. Conventionally known line-of-sight detection means such as a method of scanning and detecting the direction of the line of sight by detecting reflected light from the eyes of the laser beam with an image sensor or the like can be used.

  In the eyeglass-type communication device 1, the user moves the head while wearing the eyeglass-type communication device 1 on the head, and the beam directing directions of the antenna 4 and the antenna 5 are automatically linked accordingly. Can be made. On the other hand, the viewing angle that a human can view without moving the viewpoint is about 10 degrees, and this angle range corresponds to a directivity gain of about 26 dB. Therefore, for example, when using the antenna 4 or the antenna 5 having such a higher directivity gain, it is necessary to detect the user's line-of-sight direction and scan the beam direction. In addition, since the angle range in which the viewpoint is moved by rotating the eyeball without rotating the human head is about 30 degrees, when using the antenna 4 or the antenna 5 having a directivity gain of 26 dB, If the scanning angle range of the beam is at least about ± 20 degrees, the directivity is appropriately adjusted by moving the head so as to face the direction of the base station 10 that supplies the video signal or the like that the user wants to acquire. Wireless communication can be performed.

  In the eyeglass-type communication device 1 according to the present embodiment, when the line-of-sight detection unit 7 detects the user's line-of-sight direction, the detection signal is sent to the control unit 8. The control unit 8 is for performing various controls such as a conversion process for causing the image display unit 6 to display a video signal or the like obtained by wireless communication using the antenna 4 and the antenna 5 or wireless communication. Although not shown, for example, it is configured by a microcomputer having a CPU (Central Processing Unit), a hard disk, an arithmetic processing unit, a RAM (Random Access Memory) 9 and the like. These units are mutually connected to the system bus, and various data and the like are input / output via the system bus, and various processes are executed under the control of the CPU.

  The hard disk also stores a processing program for controlling the beam directing directions of the antenna 4 and the antenna 5 based on the measurement result of the user's line-of-sight direction detected by the line-of-sight detection unit 7. Various processing programs may be stored in a readable storage medium instead of the hard disk, and the processing program may be read from the recording medium. The arithmetic processing unit performs beam scanning of the antenna 4 and the antenna 5 based on the measurement result of the user's gaze direction detected by the gaze detection unit 7 under the control of the CPU based on the processing program stored in the hard disk. Arithmetic processing and the like are performed.

  In such a control unit 8, when the line-of-sight direction of the user is detected by the line-of-sight detection unit 7 and the detection signal is transmitted, the beam of the antenna 4 and the antenna 5 is processed by the arithmetic processing unit based on the detection signal. A control signal for scanning is generated, and the antenna 4 and the antenna 5 are scanned based on the control signal so that the beam directing direction coincides with the viewing direction of the user as shown in FIG. In the antenna 4 and the antenna 5, for example, the phase of the supplied voltage or current is controlled based on the control signal generated by the control unit 8, and the directing direction of each beam is electrically scanned over a predetermined angular range. Is done. The beam scanning method of the antenna 4 and the antenna 5 is not particularly limited. For example, the antenna 4 can be configured to be beam tilted by changing the length of the ground plane 41, or a separate antenna. A switch or the like for changing the inclination of 4 may be provided.

  In such a glasses-type communication device 1, the user wears the head or eyeball so that the user faces the direction of the base station 10 that supplies a video signal or the like to be acquired with the glasses-type communication device 1 mounted on the head. By simply moving, it is possible to appropriately perform wireless communication with the base station 10 in the pointing direction, and to receive a video signal or the like to be acquired. Here, when a plurality of radio base stations 10 can be used around the user, the user selects the base station 10 with less head movement / rotation necessary for beam steering, It is reasonable to communicate. In order to realize this, a display for instructing the user to move and rotate the head may be performed on the image display unit 6. In order to efficiently realize such a function, a low-speed control circuit that can always exchange low-speed data between the base station 10 side and the glasses-type communication device 1 is provided separately from the high-speed communication circuit in the millimeter wave band. It is preferable. Further, in such an environment, even if it is difficult to perform high-speed communication in the millimeter wave band due to the direction and state of the head and line of sight, the radio base station 10 side makes the head or By displaying on the image display unit 6 an instruction for prompting movement / rotation of the line of sight, a communication path in the millimeter wave band can be established. This is a significant feature that can be realized by integrating the image display unit 6 and the antennas 4 and 5 as a glasses-type device. Instead of the image display unit 6, a voice output unit (not shown) such as a speaker or an earphone may be used to instruct the user to move or rotate the head by voice. In the wireless communication device 1 according to the present embodiment, an example in which moving image information and the like obtained by wireless communication between the antenna 4 and the antenna 5 and the base station 10 is displayed on the image display unit 6 has been described. However, the present invention is not limited to this, and the obtained moving image information or the like may be stored in the RAM or the like of the control unit 8 and reproduced by another image display device or the like.

  The embodiment of the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the scope of the idea of the present invention.
