FIG. 2 is a partially enlarged sectional view of FIG. 1, and the same parts as those of FIG. 1 are denoted by the same reference numerals.

In FIG. 1 and FIG. 2, an antenna device 101 for a mobile phone according to the present embodiment has a linear antenna body 106 and an upper part of an antenna body 106 which are linearly formed by, for example, a shape memory alloy. Is provided with a case member 104 disposed in the case. The antenna body 106 is colored and inserted into a cylindrical tube member 107 formed of a translucent resin or the like, and is covered by the tube member 107.

When the antenna body 106 is housed in a mobile phone (not shown), the antenna main body 106 is electrically connected to a power supply circuit (not shown) of the mobile phone via the fixing member 108. The upper contact portion 105 and the conductive lower contact portion 110 electrically connected to the power supply circuit of the mobile phone via the fixing member 108 when the antenna main body portion 106 is pulled out of the mobile phone and made to protrude, and a through hole thereof. (Not shown), the antenna body 106 and the tube member 107 are inserted therethrough. The antenna body 106 is attached to the mobile phone so as to be able to protrude and retract from the mobile phone by being screwed into the mobile phone. A conductive fixing member 108 fitted to the upper contact portion 105 and the lower contact portion 110 is provided.

The upper contact portion 105 and the lower contact portion 110 are formed integrally with the antenna main body 106. The case member 104 is attached to the tip of the upper contact portion 105 to be integrally attached to the antenna main body 106, and at least a part of the case member 104 is formed of a member having translucency. There is a case top 102 formed of a light-transmitting resin and a case bottom 103 formed of a non-light-transmitting conductive metal.

Screws (not shown) are formed on the case top 102 and the case bottom 103, respectively, and these are integrated by screwing them together. A female screw part 208 is formed at the center of the case bottom part 103, and the case member 104 is screwed with a male screw part 207 integrally formed on the upper part of the upper contact part 105, so that the case member 104 is connected to the upper contact part 105. Then, the case member 104 is attached to the antenna body 106 via the upper contact portion 105.

On the other hand, as shown in FIG. 2, in the case member 104, the helical antenna 201 which functions as an antenna and also functions as a spring member, a conductive pedestal 206, and is fixed to the pedestal 206 by soldering or caulking. A printed circuit board 203 is provided which is electrically connected. The pedestal 206 is electrically connected to the antenna body 106 via the case bottom 103, the screw 207, and the upper contact 105.

A light emitting diode (LED) 202 as a light emitting element, two rectifying diodes 204 and a smoothing capacitor 205 are fixed to the printed circuit board 203 by soldering.

The pedestal 206 is held in a state of being placed in the case bottom 103, and electrical contact between the pedestal 206 and the upper contact portion 105 is made by attaching the helical antenna 201 as described later. Realized by the power. The LED 202, the rectifying diode 204 and the smoothing capacitor 205 constitute a light emitting display circuit.

One (upper) of the helical antenna 201 contacts the inner wall of the case member 104 and the other (lower) contacts the pedestal 206, and the pedestal 206 is pressed downward by the extension force of the helical antenna 201. The pedestal 206 is electrically connected to the antenna body 106 via the case bottom 103 and the screw 207. Thus, the light emitting display circuit provided on the helical antenna 201 and the printed circuit board 203 is electrically connected to the antenna main body 106 via the pedestal 206.

When the mobile phone transmits a radio wave, the one end of the helical antenna 201 is set to a point where the maximum voltage is reached (in other words, a point where the current is zero). Connected to the midpoint.

When assembling the antenna device for a mobile phone configured as described above, the upper contact portion 105 and the lower contact portion 110 are caulked while the antenna main body 106 is inserted into the tube member 107. The antenna body 106 is attached to the antenna body 106 by a method such as that described above, and the antenna body 106 is covered with the tube member 107.

The rectifier diodes 303 and 304 and the smoothing capacitor 305 constitute a drive circuit. The rectifying diodes 303 and 304 are constituted by Schottky barrier diodes having a small voltage drop, and constitute a half-wave current circuit.

When transmitting a radio wave from a mobile phone, for example, when answering an incoming call of the mobile phone, an AC signal is output from a connection point between the antenna body 301 and the helical antenna 302, whereby the rectifying diodes 303 and 304 are output. An alternating current is supplied to the connection point. The AC current is rectified by the rectifying diodes 303 and 304, and then smoothed by the smoothing capacitor 305. The DC current is supplied to the LED 306, and the LED 306 emits light. Therefore, when the mobile phone responds to the incoming call, the LED 306 emits light, so that the incoming light emission is substantially displayed.
