The ground terminal 111 is connected to the negative electrode of the battery 160, for example, via the via conductor and the first conductor 120.

  The RF circuit 110 outputs an RF signal from the RF signal output terminal 114. The RF signal is, for example, a signal generated based on the identification information described above or the information such as the biological information described above.

  The antenna includes a first conductor 120 provided on the back surface of the substrate 101, and conductor portions (a second conductor 130 and an erecting portion 131) spaced apart from the first conductor 120.

The second conductor 130 is provided at a position facing the first conductor 120 with respect to the substrate 101 as described above.

The substrate 101 has electrical insulation.
The battery 160 supplies power to the RF circuit 110 by the movement of the conductor portion (the second conductor 130 and the standing portion 131). The battery 160 is, in this example, a button battery or a coin battery. The battery 160 is an example of a power supply unit. The positive electrode of the battery 160 in the first state is electrically connected to the second conductor 130 via the contact surface 190. For example, the battery 160 may be disposed in advance in a state of being electrically connected to the pattern 121, and may be electrically connected to the moved second conductor 130. Also, the battery 160 may be provided in advance in a state of being electrically connected to the second conductor 130, and may be moved together with the second conductor 130 to be electrically connected to the pattern 121.

  Also, in this example, a low pass filter 170 is connected in series between the battery 160 and the power input terminal 113 of the RF circuit 110. The low pass filter 170 suppresses the inflow of high frequency noise to the power supply input terminal 113. The low pass filter 170 includes, for example, an inductive element such as an inductor, and the inductor is connected in series between the battery 160 and the power input terminal 113 of the RF circuit 110.

  Further, in this example, a high pass filter 180 is connected in series between the standing portion 131 (conductor portion) and the RF signal output terminal 114 provided in the RF circuit 110. The high pass filter 180 suppresses the inflow of low frequency noise to the RF signal output terminal 114. The high pass filter 180 includes, for example, a capacitive element such as a capacitor, and the capacitor is connected in series between the standing portion 131 (conductor portion) and the RF signal output terminal 114 provided in the RF circuit 110. It is preferable that a second matching circuit is connected between the erected portion 131 (conductor portion) and the RF signal output terminal 114 provided in the RF circuit 110, and the high pass filter 180 is one of the second matching circuits. It is preferable to connect in series between the standing portion (conductor portion) as a portion and the RF signal output terminal 114 provided in the RF circuit 110. The second matching circuit is provided, for example, for impedance matching between the conductor portion (the second conductor 130 and the standing portion 131) and the second output line 141 and the first output line 140, and as an example, It further includes a capacitive element such as a capacitor connected to at least one of the one output line 140 and the second output line 141 and the first conductor 120 or an inductive element such as an inductor. The communication device 100 may include a band pass filter instead of the high pass filter 180.

  The communication device 100 including the antenna having the above-described configuration uses the potential of the first conductor 120 as a reference potential to the second conductor 130 and the erecting portion 131 from the RF circuit 110 via the first output line 140 and the second output line 141. An RF signal is applied. Here, it is desirable that the electrical length of the antenna be designed to be equal to half (λ / 2) of the wavelength λ of this RF signal. The electrical length of the antenna can be designed to be equal to half the wavelength λ of the RF signal by adjusting the inductance of the inductive element and the capacitance of the capacitive element included in the second matching circuit.

Next, the start of the operation of the communication device 100 will be described with reference to FIG.
FIG. 3 is a diagram illustrating an example of the method of starting the operation of the communication device 100.

  The communication device 100 illustrated in FIG. 3 is in a state in which the second conductor 130 and the erected portion 131 described above and the substrate 101 are separated. In this example, the battery 160 is previously fixed to the second conductor 130. A conductive adhesive or the like is used to fix the battery 160. The communication device 100 also includes a housing 10. The housing 10 is provided at a position covering the communication device 100. The second conductor 130 or the substrate 101 is fixed to a part of the housing 10, and a part of the housing 10 is movable together with the second conductor 130 and the erected portion 131 or the substrate 101. The shape of the housing 10 is a rectangle corresponding to the shapes of the second conductor 130 and the substrate 101.

The housing 10 includes, for example, a cover 20 and a base 30. The cover 20 and the base 30 fit together.
The second conductor 130 and the standing portion 131 are fixed to the cover 20. The base 30 is provided with a substrate holding unit 31 for holding the substrate 101 inside. The substrate holding portion 31 is a groove having a size capable of accommodating the substrate 101. The substrate holding unit 31 restricts the movement of the substrate 101 in the direction parallel to the XY plane and the movement in the direction parallel to the Z-axis direction. The substrate 101 is held by the substrate holding unit 31.

  The second conductor 130 and the standing portion 131 are movable in a direction including a direction component parallel to the surface of the substrate 101. The second conductor 130 and the erected portion 131 move, for example, in the direction from the Y-axis negative side to the Y-axis positive side with respect to the substrate 101. By the movement of the second conductor 130 and the erected portion 131, the end on the Z-axis negative side of the erected portion 131 contacts the conductor connection portion 142, and is electrically connected to the second output line 141 and the first power line 150. Connected to In addition, the negative electrode of the battery 160 is electrically connected to the pattern 121 and electrically connected to the first conductor 120 by the movement of the second conductor 130 and the standing portion 131. Thus, power is supplied from the battery 160 to the RF circuit 110. The RF circuit 110 supplied with electric power from the battery 160 has the erecting portion 131 and the second conductor 130 via the first output line 140, the high pass filter 180 and the second output line 141 from the RF signal output terminal 114. And output an RF signal. The RF signal is emitted as a radio wave from the standing portion 131 and the second conductor 130. In other words, the cover 20 is moved from the Y-axis negative side of the base 30 toward the Y-axis positive side. By moving the cover 20 from the Y-axis negative side of the base 30 toward the Y-axis positive side, the cover 20 and the base 30 are fitted, and the second conductor 130, the standing portion 131, and the conductor connection portion 142 are engaged. (Substrate 101) is fixed.

In addition, although the case where the 2nd conductor 130, the standing part 131, and the conductor connection part 142 (board | substrate 101) were fixed by the housing | casing 10 was demonstrated in this example, it is not restricted to this. The second conductor 130 and the erected portion 131 may be fixed by a conductive adhesive in a state of being electrically connected to the conductor connection portion 142 (substrate 101).

  In this example, although the case where battery 160 was beforehand fixed to the 2nd conductor 130 was explained, it is not restricted to this. The battery 160 may be fixed to the pattern 121 in advance.

[Operation of Communication Device 100 (2)]
Next, the start of the operation of the communication device 100 will be described with reference to FIGS. 4 and 5.
FIG. 4 is a diagram illustrating an example of the method of starting the operation of the communication device 100.
FIG. 5 is a diagram showing an example of the first state of the communication device 100. As shown in FIG.

  The communication device 100 illustrated in FIG. 4 is in a state in which the second conductor 130 and the erected portion 131a described above and the substrate 101 are separated. In this example, the negative electrode of the battery 160 is fixed in advance to the pattern 121 provided on the substrate 101 and electrically connected. A conductive adhesive or the like is used to fix the battery 160.

The standing portion 131a includes a convex portion 135a. The convex portion 135a is provided at the end on the Z axis direction negative side of the standing portion 131a.
The substrate 101 is provided with a conductor connection portion 142a having a concave portion 143A fitted with the convex portion 135a. The concave portion 143A is, for example, a hole penetrating the substrate 101. The convex portion 135a fitted to the concave portion 143A restricts the movement of the second conductor 130 and the standing portion 131a in a direction parallel to the X-axis direction and a direction parallel to the Y-axis direction. The recess 143A is not limited to the hole penetrating the substrate 101, and may be a groove.

  The second conductor 130 and the standing portion 131 a are movable in a direction including a direction component perpendicular to the surface of the substrate 101. The second conductor 130 and the standing portion 131 a move, for example, in the direction from the Z-axis positive side to the Z-axis negative side with respect to the substrate 101. By the movement of the second conductor 130 and the standing portion 131a, as shown in FIG. 5, the convex portion 135a of the standing portion 131a engages with the concave portion 143A of the conductor connection portion 142a. Thus, the erected portion 131 a and the conductor connection portion 142 a are electrically connected to the second output line 141 and the first power supply line 150. Further, the positive electrode of the battery 160 is in contact with the second conductor 130 and is electrically connected by the movement of the second conductor 130 and the standing portion 131a. Thus, power is supplied from the battery 160 to the RF circuit 110. The RF circuit 110 supplied with power from the battery 160 outputs an RF signal from the RF signal output terminal 114. The RF signal is radiated as a radio wave from the standing portion 131 a and the second conductor 130. The erected portion 131a may be fixed by a conductive adhesive in a state of being electrically connected to the conductor connection portion 142.

  In addition, although the case where the battery 160 was previously fixed to the pattern 121 was demonstrated in this example, it is not restricted to this. The battery 160 may be previously fixed to the second conductor 130.

  In the present embodiment, the conductor portion (the second conductor 130 and the standing portion 131) moves relative to the substrate 101 to connect the conductor portion and the RF signal output terminal 114 of the RF circuit 110, and The pattern 121 on the substrate 101 and the battery 160 are electrically connected, and the battery 160 and the power input terminal 113 of the RF circuit 110 are electrically connected via the conductor portion. The communication device 100 in the first state outputs an RF signal from the conductor. That is, the battery 160 supplies power to the RF circuit 110 through the conductor connection portion 142 by moving the conductor portion to a predetermined position. Thus, the communication device 100 does not generate an RF signal until the conductor moves to a predetermined position. That is, the communication device 100 can suppress the power consumption of the battery 160 until the wireless communication operation is performed.

  In the above description, although the case where the end on the Z-axis negative side of the standing portion 131 and the conductor connection portion 142 are directly connected to each other is connected, the present invention is not limited thereto. The end on the Z-axis negative side of the standing portion 131 and the conductor connection portion 142 may be connected via an adhesive having conductivity, a connector having conductivity, or the like.
