In addition, described the 1st, refer at the perpendicular direction in the plane that is positioned at described flat board member 12 towards the face of side's side, following the 2nd face refer to towards with the face of described the 1st opposition side.
That is, in described antenna element 1, on described the 1st of dielectric basement membrane 11, be equiped with the conductive plate parts 12 and the antenna 13 of the non junction shape of central opening.Described antenna 13 with and the inner peripheral 12a of described conductive plate parts 12 between have the state of gap S, with being installed in like that on the basement membrane 11 of the opening that is positioned at these conductive plate parts 12.
In the present embodiment, described antenna element 1 is installed on the discoid detected body 2.
In detail, described detected body 2 has and is configured to the aluminium-vapour deposition layer 21 as electroconductive component roughly coaxial with rotating shaft X, and this aluminium-vapour deposition layer 21 is non junction shapes that central authorities are made as opening.
Described antenna element 1, is installed in the 2nd face of basement membrane 11 on the 1st of described detected body 2 in the mode that strides across the inner peripheral 21a of described aluminium-vapour deposition layer 21 in the vertical view of described rotating shaft X with at least a portion of described conductive plate parts 12.
Promptly, described antenna element 1, with described aluminium-vapour deposition layer 21 not overlapping state on vertical view, be installed on the described detected body 2 with the overlapping mode of described conductive plate parts 12 on the vertical view with at least a portion of this aluminium-vapour deposition layer 21 with the central opening of described conductive plate parts 12.
Described antenna element 1, for example, film by conductivity such as lamination aluminium on the basement membrane 11 that is formed by various resin flakes with insulating properties etc. is etched into described conductive film the shape of regulation and forms conductive plate parts 12 and antenna 13, thereby form.
In described antenna 13, store the information (information of detected body 2, for example data folder name, identiflication number, memory time etc.) of regulation.And then, on described antenna 13, be equipped with and can send the IC chip 131 that receives described information.
In addition, described antenna 13 both can constitute sent-received message always, also can constitute and send the described information that receives when receiving the signal of solicited message.
On the other hand, discoid detected body 2 is made as disc storage media such as CD-ROM, DVD-ROM.
Described disc storage medium; for example have polycarbonate resin 22a, by AM aluminum metallization etc. and lamination on the part of this resin bed 22a electroconductive component 21 and with the polycarbonate resin 22b of the protection usefulness of the mode lamination that covers described electroconductive component 21, described electroconductive component 21 is by resin bed 22a, 22b clamping.
In addition, discoid detected body 2 generally is made as the data read face with a face among the 1st and the 2nd of electroconductive component 21, another face is made as the label surface that is formed with label 23 (printing or paste thin slice).
In the present embodiment, described antenna element 1 is installed in the label surface side.
In addition, can be described basement membrane 11 and described detected body 2 is bonding by bonding agent, perhaps also described basement membrane 11 itself can be made adhesive bond layer, this basement membrane 11 directly is bonded on the detected body 2.
In described wireless communication structure, described antenna 13, with and the inner peripheral 12a of described conductive plate parts 12 between have state, being installed in like that on the described detected body 2 of gap S with the opening that is positioned at these conductive plate parts 12.That is, described antenna 13 is configured to not contact with conductive plate parts 12 on vertical view and by the state of its encirclement.
And then in the present embodiment, described conductive plate parts 12 with such at the inner peripheral 21a of the described electroconductive component 21 that strides across described detected body 2 around the whole circumference of described rotating shaft X ground on vertical view, are installed on the detected body 2.That is to say, described antenna element 1, with the inner peripheral 21a of the described electroconductive component 21 in the described detected body 2 (with reference to Fig. 1) on the vertical view between the inner peripheral 12a of described conductive plate parts 12 and outer peripheral edges 12b like that, be installed on the described detected body 2.
In described antenna element 1, described antenna 13 is surrounded by described conductive plate parts 12, the signal that makes 12 pairs of described conductive plate parts be sent reception by described antenna 13 interact (interference).Promptly, by being carried out interactional described conductive plate parts 12 with described antenna 13 encirclements by described antenna 13 sending the signal that receives, thereby substantially will get rid of by the electroconductive component 21 or the caused interactional influence of other electroconductive component of the outside that is present in described conductive plate parts 12, thus, determine uniquely that by the physical property of described antenna 13 and described these conductive plate parts 12 signal that is undertaken by described antenna 13 sends the resonance frequency when receiving.
And then, in described antenna element 1, be configured to: the described electroconductive component 21 in the detected body 2 on vertical view not with the central opening overlaid of described conductive plate parts 12, and described conductive plate parts 12 stride across the inner peripheral 21a of described electroconductive component 21 with the state of described basement membrane 11 of clamping and resin bed 22 on vertical view.Therefore, overlooking overlapping part (by the inner peripheral 21a of the electroconductive component 21 of detected body 2 and the outer peripheral edges 12b institute area surrounded of conductive plate parts 12) works for dielectric capacitor as the described resin component 22 with described insulating properties basement membrane 11 and detected body 2.
Thus, produce electrostatic capacitance between the electroconductive component 21 in described conductive plate parts 12 and described detected body 2, therefore described conductive plate parts 12 and described electroconductive component 21 can be regarded as the state of electric property ground combination.
Therefore, the transmission of described antenna 13 is received electric wave exert one's influence (interaction), in fact just the described conductive plate parts 12 that leave predetermined gap S in advance and dispose around this antenna 13 can prevent effectively that electroconductive component 21 or other the electroconductive component in the described detected body 2 from producing interact (interference) to sending the reception electric wave.
Like this, surround by the described conductive plate parts 12 of non junction shape by the described antenna 13 that will form in the plane, and on vertical view, be not positioned at the state of the central opening of described conductive plate parts 12 with the described electroconductive component 21 of described detected body 2, it is overlapping on vertical view to make described conductive plate parts 12 and described electroconductive component 21 dielectric state with clamping, can prevent effectively that thus the communication characteristic of described antenna 13 is subjected to the influence of the described electroconductive component 21 of described detected body 2, thereby can determine the communication characteristic of this antenna 13 uniquely.
In addition, in the present embodiment, conductive plate parts 12 are installed in the mode of the whole circumference of the inner peripheral 21a of the electroconductive component 21 that strides across detected body 2 on vertical view, so can increase the overlapping region of the parts of conductive plate described in the vertical view 12 and described electroconductive component 21.According to such formation, can increase the zone (electrostatic capacitance) of electric property ground combination, can make described conductive plate parts 12 and described electroconductive component 21 electric property ground assimilations, thereby more effectively reduce the interactional influence that produces by described electroconductive component 21.
Electrostatic capacitance between described conductive plate parts 12 and the described electroconductive component 21 is big more, just can reduce the interactional influence that produces by described electroconductive component 21 more, so preferred described conductive plate parts 12 increase in the overlapping region on the vertical view as much as possible with described electroconductive component 21 on the direction of footpath.According to such formation, can increase the area (area of overlapping region) of relative to each other described conductive plate parts 12 and described electroconductive component 21, thereby electrostatic capacitance can increase also pro rata with this area.
But,, then can damage the function as storage medium of described detected body 2 if described conductive plate parts 12 arrive the data storage areas in the described electroconductive component 21 on vertical view.Therefore, the outer peripheral edges 12b of preferred conductive plate parts 12 is arranged in the inboard of inner peripheral 21b of data area of the electroconductive component 21 of detected body 2.
Because the distance of electrostatic capacitance and described conductive plate parts 12 and described electroconductive component 21 is inversely proportional to, so preferred described distance (i.e. the dielectric thickness that is formed by the resin component 22 of basement membrane 11 and detected body 2) is as much as possible little.
In addition, it is different preferably to constitute the resonance frequency of the resonance frequency of described antenna 13 and described conductive plate parts 12.According to such formation, become and be provided with 2 resonance frequencys, when integrally seeing described antenna element 1, can enlarge the frequency band of antenna.The resonance frequency of described antenna 13 and described conductive plate parts 12, length that can be by changing described antenna 13 and/or described conductive plate parts 12, width, thickness etc. and suitably determine.
In the present embodiment, described antenna 13 is set as dipole antenna.
Described conductive plate parts 12, have and be configured to annulus 121 roughly coaxial with the rotating shaft X of described detected body 2 on vertical view, with be configured to center (center of gravity) X with described detected body 2 be benchmark and with the described dipole antenna 13 balance portion 122 of symmetry roughly, and described annulus 121 and described balance portion 122 connect via connecting portion 123 electric property ground.In addition, described annulus 121, described balance portion 122 and described connecting portion 123 are to carry out etching by the film to conductivity such as aluminium to form as mentioned above.
At this moment, the described annulus 121 of conductive plate parts 12, stride across described detected body 2 described electroconductive component 21 inner peripheral 21a and dispose.And, described balance portion 122 be configured in center X with described detected body 2 be benchmark and with described antenna (dipole antenna) 13 roughly on the position of symmetry.And described annulus 121 is connected via connecting portion 123 electric property ground with described balance portion 122.
Like this, be configured to the rotating shaft X of described detected body 2 roughly coaxial by described annulus 121 with described conductive plate parts 12, and with the rotating shaft X that described antenna 13 and described balance portion 122 are configured to described detected body 2 is roughly symmetry of benchmark, can the dynamic balancing when making discoid described detected body 2 rotations keep even on whole wireless communication structure thus.
In addition, described balance portion 122 via described connecting portion 123 with described annulus 121 electric property combine.Therefore, can prevent that described balance portion 122 from bring influence for the communication characteristic of described antenna 13.
In addition, in the present embodiment, the both ends of described balance portion 122 and central portion are connected with described annulus 121 electric property ground via described connecting portion 123, but the present invention is not limited to this state.
In addition, described balance portion 122 also can replace making it to be connected with described annulus 121 electric property ground, and make it can not influence the resonance frequency that sends the signal of receptions by described antenna 13 its panelization.

In addition, shown in Fig. 9 (b), for reactive component, peak value (resonance) frequency that does not have the wireless communication structure of described electroconductive component 21 is about 2.35GHz, and peak value (resonance) frequency with wireless communication structure of described electroconductive component 21 is about 2.40GHz.Therefore, both side-play amounts are 0.05GHz.
Comparative example
As a comparative example, have described antenna 13 and do not have the wireless communication structure of described conductive plate parts 12, carried out the parsing identical with described embodiment for formation.
At first, described antenna 13 is resolved for the wireless communication structure of dipole antenna (having removed the formation of described conductive plate parts 12 in Fig. 8).
The analysis result of expression comparative example in Figure 10.Figure 10 (a) represents frequency-resistance components characteristic, and Figure 10 (b) represents frequency-reactive component characteristic.
Shown in Figure 10 (a), for resistance components, peak value in the wireless communication structure that does not have described electroconductive component 21 (resonance) frequency is about 2.35GHz, and peak value in the wireless communication structure with described electroconductive component 21 (resonance) frequency is about 1.90GHz.Therefore, both side-play amounts are 0.45GHz.
In addition, shown in Figure 10 (b), for reactive component, peak value in the wireless communication structure that does not have described electroconductive component 21 (resonance) frequency is about 2.25GHz, and peak value in the wireless communication structure with described electroconductive component 21 (resonance) frequency is about 1.85GHz.Therefore, both side-play amounts are 0.40GHz.
