Wristwatch-type communication device and antenna therefor
First Claim
1. A wristwatch-type communication device, comprising:
- a case, an antenna housed in the case and including a first conductor portion having a generally ring shape;
a second conductor portion opposed to and spaced apart from the first conductor portion to form an internal space therebetween, said second conductor portion having a generally ring shape, a space portion for housing a component therein and interrupting the second conductor portion, and end portions sandwiching the space portion;
a third conductor portion connected between the first and second conductor portions and having two connecting conductors connected to the end portions of the second conductor portion for electrically connecting the first and second conductor portions;
a first feeder terminal connected to the first conductor portion and;
a second feeder terminal connected to the second conductor portion, and a support frame, a display panel supported by the support frame, a battery, and a circuit board stacked to the battery and electrically connected to the battery and the first and second feeder terminals, said support frame and circuit board being disposed in the internal space between the first and second conductor portions so that one of the first and second conductor portions is positioned on a side of the circuit board opposite to the support frame and outward thereof, and the other of the first and second conductor portions is positioned on a side of the support frame opposite to the circuit board and outward thereof.

Abstract
A device includes: a communication device case 2 having therein a display panel 13 supported by a support frame 12 and a circuit board 15 stacked with a battery 22 and electrically connected to the battery 22; and an antenna 6 housed in the communication device case 2, the antenna having a first conductor portion 23 formed in a ring, a second conductor portion 24 opposed to the first conductor portion 23 at a predetermined interval, and a third conductor portion 25 for electrically connecting the first conductor portion 23 and the second conductor portion 24. And a communication module assembly 3 is formed by disposing a communication device module in the antenna 6, the communication device module including the circuit board and the support frame. And the first conductor portion 23 of the antenna 6 in the communication device module assembly is positioned on a side of the circuit board 15 opposite to the support frame and outward, and the second conductor portion 24 is positioned on a side of the support frame 12 opposite to the circuit board and outward. As a result, the conductor portion of the antenna is positioned in an outermost portion of the communication device module. Therefore, the dimension of strap in the thickness direction and the dimension of the communication device case in the plane direction can be set to small values, respectively. In addition, favorable feeling of wearing the communication device can be obtained, and the size of the communication device as a whole can be made small.
