In the metal box housing antenna 1 with slit used in the present invention, the slit 1c of the metal box 1b is arranged orthogonal to the direction of the PHS antenna 1a as shown in FIG. Some are arranged in parallel as shown in (B). Here, the slit 1c has the same effect as that of the dipole antenna, so that the callable area which is non-directional as shown in FIG. 3 (A) has directivity as shown in FIG. 3 (B). Can do. At this time, the slit length is set to, for example, one wavelength 160 mm and a half wavelength 80 mm of the PHS signal 1.9 GHz in order to make the antenna effect appear. Furthermore, by placing the metal box-accommodating antenna 1 with slits in the metallic box 1b with slits, it is possible to reduce the electric field strength in the room and to reduce the area where communication is possible. Therefore, it is effective not only for the PHS antenna as described in FIG. 1 but also for an antenna that can be used for position information such as a wireless tag.
[0017]
The metal box 1b with a slit is made of, for example, a metal material such as SUS, and when the slit 1c having a length of one wavelength of 160 mm with a PHS signal of 1.9 GHz is provided, the width is set to 10 mm, as shown in FIG. A vertical and horizontal 300 to 400 mm metallic lid portion 1b1 and a metallic box portion 1b2 having a height of about 40 mm to 60 mm as shown in FIG. 4B.
