  According to the present invention, there is provided a reflector that reflects radio waves on a radio unit body that is used by inserting and connecting a wireless unit that is mounted with an antenna having an omnidirectional or relatively weak directional characteristic such as a PCMCIA card. Since the wireless unit antenna is disposed at the focal position of the reflector, the wireless communication device operates as an antenna having a relatively strong directional characteristic in a specific direction due to electromagnetic interaction between the wireless unit and the reflector. As a whole, the effect of exhibiting relatively strong directivity can be obtained.

  As described above, according to the first embodiment of the present invention, a reflector that reflects radio waves is provided on a wireless device body in which a wireless unit such as a PCMCIA card is inserted and connected, and an electromagnetic wave between the wireless unit and the reflector is provided. Because it is configured to act as an antenna having a relatively strong directional characteristic in a specific direction due to dynamic interaction, the wireless unit's omnidirectional or relatively weak directional characteristic can be changed without replacing it with a highly directional antenna. The antenna can be used as an antenna having a relatively strong directional characteristic.

  Therefore, when the wireless communication device of the present invention is used as a wireless LAN terminal, the antenna directivity can be matched with the direction of the access point.

  Further, according to the fourth embodiment, since the reflector has a parabolic mirror surface with a concave horizontal section, it is possible to obtain stronger directivity in the horizontal direction.

First, a first embodiment of the present invention will be described with reference to the drawings.
1A and 1B are diagrams showing a configuration of a wireless communication device according to the present invention, where FIG. 1A is a front view and FIG. 1B is a side view. 2A and 2B are diagrams for explaining the structure of the reflector. FIG. 2A is a front view, FIG. 2B is a plan view, and FIG. 2C is a side view. FIGS. 3A and 3B are diagrams for explaining the mounting positions of the reflector and the wireless unit of the wireless communication device body. FIG. 3A is a front view, FIG. 3B is a plan view, and FIG.

  Referring to FIG. 1, a connector 1 for mounting a wireless unit, an antenna 2, a wireless unit 3, a reflector 4, and a wireless device body 5 are configured. The wireless unit 3 assumes the shape of a PCMCIA card, and the antenna 2 is mounted inside the wireless unit.

  The antenna 2 has a radiation characteristic of omnidirectionality or a relatively weak unidirectional characteristic close to omnidirectionality.

  As shown in FIGS. 2A, 2B, and 2C, the reflector 4 forms a parabolic mirror surface having a concave vertical cross section.

  A wireless unit insertion hole 10 for inserting the antenna 2 of the wireless unit 3 is provided below the horizontal central axis of the parabolic mirror surface. Further, a reflector fixing plate 11 having a predetermined width, length, and thickness is provided in the vertical direction from the outer wall of the parabolic mirror surface.

  As shown in FIGS. 3 (A) and 3 (B), the radio unit main body 5 has a radio unit slot 6 for attaching / detaching the edgeless unit 3 to / from the connector 1 and a reflection for attaching / detaching the reflector 4 to the upper end surface. It has a device slot 7.

  The wireless unit 3 is inserted into the wireless unit slot 6 and connected to the connector 1 inside the wireless device main body. The reflector 4 is fixed by a frictional force by inserting the reflector fixing plate 11 into the reflector slot 7. The structure in which the reflector 4 is held by the frictional force of the reflector slot 7 is because the ease with which the wireless unit 3 can be attached to and detached from the wireless device main body is taken into consideration, but this holding method is not limited. Any method may be used as long as it is fixed.

  Next, the operation of the first embodiment will be described.

  First, a wireless unit 3 having an antenna 2 having omnidirectionality or relatively weak directivity is inserted into a wireless unit slot 6 of the wireless communication device body 5 shown in FIG. After the fitting, the reflector 4 is inserted and fixed in the reflector slot 7.

  At this time, as shown in FIG. 2, the wireless unit 3 is inserted through the wireless unit insertion hole 10 of the reflector 4 so that the antenna 2 is positioned within the parabolic mirror surface of the reflector 4. In other words, the antenna 2 of the wireless unit 3 is disposed at a substantially focal position on the parabolic mirror surface of the reflector 4.

  Therefore, among the radio waves radiated from the antenna 2 of the wireless unit 3, the radio waves radiated forward (in the direction opposite to the parabolic mirror surface of the reflector) propagate forward as they are because there are no obstacles. The radio wave radiated in the specular direction is reflected by the mirror surface and propagates forward as a parallel radio wave because the position of the antenna 2 is arranged at the focal point of the reflector.

  The directivity characteristic of the antenna 2 in this case is strong directivity in the vertical direction because the vertical cross section of the reflector 4 is a parabolic mirror surface.

  Thus, the wireless communication device of the present invention can easily radiate radio waves having relatively strong directional characteristics.

A radome 8 is arranged so as to do this.

  A metal foil serving as a director 9 is fixed to the radome 8 at a predetermined position on the front surface facing the antenna 2.

  Since the radome 8 is made of a dielectric material such as plastic that allows radio waves to pass therethrough, the improvement in directivity due to the electromagnetic interaction between the antenna 2 and the reflector 4 is the same as in the first embodiment. However, the directivity is further improved by the action of the director 9 positioned in front of the propagation direction of the radio wave.

  In the above configuration, the directivity can be improved even if the reflector 4 is deleted and the metal foil serving as the director 9 is fixed to a predetermined position on the front surface of the radome 8 facing the antenna 2. Although possible, the directivity is inferior to that of the case where the reflector 4 is provided.

  The support base 13 has a trapezoidal long side having U-shaped grooves 14 on the short side on the left and right ends of the flat plate so as to be perpendicular to the flat plate to form a side plate. A support shaft 12, which is a cylindrical protrusion disposed on both side surfaces of the side plate 5, is fitted into a U-shaped groove 14 on the short side of the side plate so as to be rotatably supported.

  In this state, the wireless communication device main body 5 is rotated back and forth to adjust the antenna 2 in a desired direction, and as shown in FIG. 5C, a direction orthogonal to the U-shaped groove 14 on the end surface of the side plate. It fixes with the fixing screw 15 arrange | positioned. This fixing method is not limited, and any method can be used as long as the wireless communication device body 5 can be fixed at a desired position. For example, a method of fixing by the frictional force of the U-shaped groove 14 may be used.

  When the wireless communication device body 5 with the wireless unit and the reflector thus mounted is mounted on the support base 13 and used on the desk, the azimuth direction of the wireless communication device can be adjusted by the direction of the support base. In addition, by adjusting the direction of the antenna 2 by the tilt mechanism, it is possible to easily fix a relatively strong directional characteristic direction toward the communication partner (access point).

Next, a fourth embodiment will be described with reference to the drawings.
6A and 6B are diagrams for explaining the structure of the reflector according to the fourth embodiment. FIG. 6A is a front view, FIG. 6B is a plan view, and FIG.

  As shown in FIGS. 6A, 6B, and 6C, the reflector 4 forms a parabolic mirror surface having a concave horizontal cross section.

Further, a reflector fixing plate 11 having a predetermined width, length, and thickness is provided in the vertical direction from the outer wall of the parabolic mirror surface.
