Abstract

A light emitting antenna of a cellular phone comprises an insulative guided light scattering/radiating member arranged within a transparent or translucent antenna top protection cap fixed with the main body portion. The surface of the guided light scattering/radiating member is made coarse, and a helical antenna is wound around and held by the main body portion. A light introducing portion is held by the antenna top protection cap. A light source is arranged in a position as opposed to an end surface of the guided light scattering/radiating member. Power of the light source is supplied from a battery without using a transmitted/received electric wave.

Claims

1. A wireless communication device, comprising an antenna whose top emits light, wherein

the antenna comprises

an antenna top having a transparent or translucent light guiding nature,

a guided light radiating member that is arranged within said antenna top, and holds an antenna, and

a light source which is arranged close to a bottom of said guided light radiating member, and emits a light independently of an electric wave transmitted/received by the antenna, and inputs said light to said guided light radiating member.

3. The wireless communication device according to claim 1 or 2, wherein

said light source has two or more light-emitting elements whose emitted light colors are different.

4. The wireless communication device according to claim 1, 2, or 3, further comprising

a control unit controlling a color, brightness, or an illumination interval of light emitted from said light source based on a program or an external instruction input operation.

5. The wireless communication device according to claim 4, wherein

said control device controls the color, the brightness, or the illumination interval of the light emitted from said light source based on a transmitted/received electric wave state, a remaining amount of a battery, a time, and a communication duration of a local main body device, or proceeding contents of a game played by the local main body device.

2. A wireless communication device, comprising an antenna whose top emits light, wherein

the antenna comprises

a tube-shaped antenna accommodating portion whose inner surface is processed to be a mirror,

a light source arranged at a bottom end of said antenna accommodating portion,

a stick antenna portion that is held, to be freely extended or retracted, by said antenna accommodating portion, comprises a top portion having a transparent or translucent light guiding nature, and comprises guided light radiating member, which externally radiates input light from a surface, within the top portion, and

an optical fiber, which is included only within said stick antenna portion, light emitted from said light source or light reflected from the mirror of the inner surface of said antenna accommodating portion is input to, and guides and relays the input light to the guided light radiating member within the top portion.
