[Problems to be solved by the invention]

 However, the conventional display device must be used integrally with the antenna of the mobile phone, and the antenna of the mobile phone is replaced with a dedicated antenna having a built-in display device. Must be mounted, which causes problems such as troublesome replacement and mounting, and a load of the display device applied to the antenna of the mobile phone.

The present invention has been made in view of such circumstances, and has as its object to increase the height of a mobile phone that can be used away from the antenna of the mobile phone and that does not require antenna replacement or attachment to the antenna tip. An object of the present invention is to provide a sensitive radio visual observation device.

[Means for Solving the Problems]

 A high-sensitivity radio-wave viewing apparatus for a mobile phone according to claim 1 is a radio-wave viewing apparatus in which a receiving antenna, a rectifying Schottky diode, and a light-emitting element are combined. Alternatively, it is characterized by combining a resonance circuit wound in a round coil shape.

According to claim 2, the length of the conductive material is about 135 to 140 [mm] for an 800 MHz mobile phone, and is about 95 to 100 [mm] for a 1.5 GHz mobile phone. It is characterized by the following.

According to a third aspect of the present invention, the radio wave viewing device is used at a position separated from an antenna of a mobile phone by increasing the reception sensitivity of the radio wave viewing device by combining the resonance circuits. .

[0008]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings. FIG. 1 shows the length of the conductive material, and FIGS. 2 to 5 show the examples.

FIG. 1 is a diagram showing the length of a conductive material 1 that forms a resonance circuit. For an 800 MHz mobile phone, it should be around 135-140 [mm], and for a 1.5 GHz mobile phone, it should be around 95-100 [mm] from the viewpoint of improving the receiving sensitivity.

FIG. 2 and FIG. 3 show a rectangular coiled resonance circuit 2 in which a conductive material is wound in a square shape or a round coiled resonance circuit 3 in which a conductive material is wound in a round shape, a receiving antenna 11 and a rectifier. FIG. 1 is a perspective view showing an embodiment in which a short-circuit shot key diode 12 and a radio wave viewing device 10 including a light emitting element 13 are combined.

FIG. 4 and FIG. 5 show that the rectangular coil-shaped resonance circuit 2 or the round coil-shaped resonance circuit 3 is formed by a substrate pattern in order to make the resonance circuit and the radio-wave viewing apparatus 10 as flat as possible. FIG. 3 is a diagram showing an embodiment in which a receiving antenna 11 of the device 10 is also configured by a substrate pattern.

[0012]

[Effects of the Invention] According to the high-sensitivity radio-wave viewing device for a mobile phone of the present invention, the reception sensitivity of the radio-wave viewing device is increased by the coil-shaped resonance circuit, and the light-emitting element emits light even at a position away from the antenna of the mobile phone. This eliminates the need to attach to the tip of the antenna of a mobile phone, and eliminates the need for antenna replacement and load on the antenna. It can also be applied to new accessory products such as mobile phone straps.
