PROBLEM TO BE SOLVED: To lower the cost with simple constitution and to avoid the influence of a multipath by providing a moving means which moves a reflector along the periphery of a plate. SOLUTION: A PCMCIA card package 1 is connected to antennas 2. The antennas 2 are arranged on the plate 3 surrounding the antennas. In a semicircular plate 3, a long guide 6 is arranged. The reflector 9 in a plane or another shape is arranged in the guide 6 with metal or other materials, and this reflector 9 is equipped with a reflection part and a pin 10. The reflector 9 can be moved around the plate 3 along the guide 6. In a normal state, the reflector 9 has an angle 11 to the longitudinal axis of a PCMCIA card. The pin is fixed to a reflection part, and consequently the reflection part rotates on a horizontal axis. |
