This is the first invention to attach an independent antenna to the band section. It is characterized by having each band separated, making it ideal for use as a pager or personal identification device. However, due to the four precepts of separate antenna FI, there is a drawback that it is inevitably limited to applications at high frequencies (100 MHz or higher).Also, although it is possible to lower the resonant frequency by transmitting ferrite to the antenna, the effect is It is not as good as a coil antenna with a magnetic core made of magnetic material.

Furthermore, reference B is a published patent published in Showa 5.
No. 9-108264 is an invention related to a band type battery device. When such a battery device or the like is attached to one of the watch sides, it is desirable that the antenna can be constructed from only one side of the watch side.

１２−２の特性と合致するからである。The other end on the watch side has a normal connection hole 2-8,
It has a function that allows the watch body 2-1 to be easily worn on the wrist. The flexible printed circuit board 2-7 of the present invention is composed of a two-layer conductor plate, and each conductor is connected to a male connector 2-9 formed inside the tongue piece 2-3 and connected to a tuning circuit or a high-frequency signal source within the watch body. -4 and female connector 2-1 on the watch body side
0, and the entire conductor plate realizes a spiral coil 2-11 in a two-dimensional manner. However, in Figure 2, it is a double-wound coil, and the connector at the end of the coil is 2.
1! It is. The spiral coil 2-11 is configured to surround a hole formed in the center of the printed circuit board, and a rubber ferrite 2-12 according to the present invention is placed there approximately in the center. Rubber ferrite is used in watches that require flexibility and toughness, although ferrite does not have high magnetic permeability and high loss.
This is because it matches the characteristics of 12-2.

の湾曲に対し、その伸縮に余裕を与える働きをする。This makes it possible to significantly lower the resonant frequency of the antenna of the present invention. If the loss of the rubber ferrite 2-12 is large, it has the disadvantage that the Q value of the coil decreases, but it also has the advantage of widening the frequency band. To ensure flexibility, the rubber ferrite is thin and flat (it is also possible to cut grooves perpendicular to the length to increase flexibility). Since some variation in the resonant frequency is unavoidable due to distortion of the tongue, it is rather desirable to increase the frequency band.
3 is electrically and mechanically connected to the female connector 2-10 on the watch body side through the male connector 2-9 formed in a part thereof, so the watch side 2-2 can be separated from the watch body 2-1. and can be distributed independently in the market. In addition, a bellows-shaped crease 2-13 is formed at the center of the tongue, that is, at the middle between the watch side and the watch body, which serves to provide room for expansion and contraction of the watch body when it is bent when worn. .
