Description of the Invention: - Technical Field of the Invention The present invention relates to an antenna device including a miniature loop antenna for use in a wireless communication device. [Prior Art] For example, in an anti-theft sensor or the like attached to a door or window of a building, data is transmitted and received by wireless communication between a sensor body attached to each window frame and a host installed in a guard room or the like. The frequency of wireless communication performed between the sensor body and the host is fixed, and the transmitting signal of the sensor body is designed to match the frequency of the zero-pass signal. The sensor body of the anti-theft sensor is designed to be as small as possible, and in cooperation with this, a miniature loop antenna is used as an antenna for transmitting signals. The micro loop antenna shortens the total length of the loop antenna (about 1/1 〇 or less of the wavelength of the transmitted signal) and has a characteristic that it is more resistant to a noise field than the micro dipole antenna. (Electronic Information and Communication Society, ed., Antenna Engineering Handbook, ρρ62·63, 〇hm, 1st edition, issued on October 30, 1980) The frequency of wireless communication in the antenna device using a miniature loop antenna F〇, the antenna is designed to minimize the loss of the transmitted signal. However, when the conductor such as the metal plate or the human body is close to the antenna device within a certain distance, the resonance frequency of the micro-ring antenna is shifted, causing the micro-ring The impedance of the antenna and the wireless circuit unit are not accurate, and thus the ability of the antenna device to transmit signals is lowered, which is a problem. Therefore, when the conventional antenna device is applied to the anti-theft sensor, it is mounted on the aluminum frame. When a window frame or the like is used, it is necessary to use a resin frame as a spacer, and the micro-ring antenna is insulated from an electric conductor such as an aluminum frame, which makes the sensor body difficult to be miniaturized, which is a problem. No. 3735635, in order to suppress the reduction of the antenna benefit of the open-loop micro-ring antenna, the use of the capacitor and the grounding of the miniature loop antenna are disclosed. [Summary] & The third is designed for solution, and the singularity caused by the conductive Zhao is reduced. In other words, the purpose of the present invention is to provide a = ray = ϋ: or maintain - ΐ: A metal body is a state in which the metal body is free from metal or does not exist. I. The performance of the wire agency (at least the wireless reception of the solution to the problem of the lead is a solution to the problem) The antenna device according to the invention includes: a miniature loop antenna formed by straight surface; formed in the circuit ί兮雷路二wit acts as a grounding pattern for the function of the dipole antenna; and compensates for the decrease in the resonant frequency of the mounting line, thereby preventing or reducing the mismatch between the miniature city antenna and the dipole antenna and the wireless circuit portion Because of the micro-ring mode current and the dipole fit current flowing in the antenna device, the effect of the resonance frequency of the r-ring and the dipole antenna of the micro-ring antenna is mutually exclusive when the conductor is brought close to each other. The result is that the resonance is not resolved, and it can prevent or reduce the connection with the ii== 录 继 继 ) ) ) ) 实施 实施 实施 实施 实施 实施 [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ [ ★ First, a first embodiment of an antenna device according to the present invention will be described. The figure shows the basic configuration of the antenna device 1A using the micro loop antenna according to the first embodiment. The antenna device 1A is composed of a circuit board 2, a micro loop antenna n, and a wireless circuit unit 12 and a control circuit unit 13 on the substrate 2 of the S1 4 1357690. The micro-ring 2 is formed between the first conductor pattern 3 and the second body pattern 4, and the antenna element 10 is formed between the first conductor pattern 3 and the second conductor pattern 4, and the conductor pattern 3 and the second conductor pattern 4 are formed on the circuit board. Installed on the money path substrate 2 and slightly]: shape. Further, the circuit board 2 is provided with a ground pattern 6, a so-called conductor pattern 3, an acid 6 secret line 7, and a power supply line 8 for supplying a money carrier type dummy antenna.

Specifically, the capacitance of the capacitor 5 is appropriately selected, The resonance rate of the micro loop antenna u is adjusted. Further, it is assumed that the resonance frequency of the antenna is a desired frequency, and the connection point pi from the power supply line 8 and the i-th conductor pattern 3 to the ground line 7 and the second conductor pattern 3 are The distance X from the connection point P2 can be adjusted to change the antenna input impedance.
從無線電路部12輸出高頻信號時，在天線裝置1A會激發高 頻電流。如圖2所示，該高頻電流可二分為：電流(微型環狀模式 電流)Ιι ’沿構成微型環狀天線11之導電路流過，有助於作為微型 環狀天線11的發射；電流(偶極模式電流瓜，沿電路基板2之長邊 方向流過，有助於作為電路基板2之長邊方向的偶極天線之發射。 微型環狀模式電流I!沿著與微型環狀天線11所構成之矩形平行的 方向’激發與微型環狀面平行的極化波之電波(水平極化波分量 SH)。另一方面，偶極模式電流I2沿著與接地圖案6之長邊方向垂 直的方向’激發與接地圖案6之長邊方向平行的極化波之電波(垂 直極化波分量Sv)。 以往’使用微型環狀天線的天線裝置中，僅著眼於流到微型 環狀天線之微型環狀模式電流h所激發的水平極化波分量，並進 行微型環狀天線之阻抗調整，以使該水平極化波分量的振幅成為 最大。偶極模式電流I2所激發的垂直極化波分量則被忽視，或者 進行調整以盡可能變小。 1357690 員不一般之天線的發射信號頻率f及輸入阻抗的特性。 L二’ 顯示對於發射信號頻率fQ係屬理想之天線特性。於 Y &計天線特性，以使天線增益相對於發射信號頻率f〇 ^綠2上’由於零件誤差或其他原因，如圖中之虛線所示， 口此圖表之上下及/或左右方向偏移。當天線特性實際上 ΪΪΪΪ所示的特性時，則於發射信號頻率fG，天線增益將從設 汁基準值大幅降低。 再說，我們知道，導電體及天線裝置靠近時，於微型環狀天 =偶極天_示相反的特性。圖3B中，實線齡假設無零件誤 _ μ孚i時的天線特性。於此狀態下，關於微型環狀天線的天線特 ，虽導電體靠近天線裝置時，如一點鏈線所示，具有往該圖表 方偏移(共振頻率上升)的性質。另一方面，接地圖案6所形成之 f極天線，當導電體靠近天線裝置時，如二點鏈線所示，具有往 4圖表左方偏移(共振頻率下降)的性質。本發明中，利用該對於靠 近之導電體的微型環狀天線與偶極天線之相反性質，而維持天線 裝置整體的天線增益，亦即抑制發射信號能力的降低，或者維 一定位準的天線增益。 、、 班依圖1所示之第1實施形態的天線裝置1A中，由於上述之微 型，狀模式電流與偶極模式電流所合成的電流流過，因此使導電 鲁體靠近時’微型環狀天線的共振頻率之上升效果與偶極天線的共 ，頻率之下降效果相互抵銷。其結果，共振頻率的變化非常小， 能防止或減少與連接到天線(微型環狀天線U與發揮作為偶極天 線之功能的接地圖案6)之無線電路部12不匹配的情況。 其次，對於圖1所示之天線裝置1A，將其具體的尺寸設計成 圖4A所示，並針對如圖4B所示地使天線裝置1Λ靠近導電體2〇 時，以有限元素法(FEM，finite dement method)進行數值計算。圖 5係顯示對於電路基板2及導電體20之距離D的天線之共振頻率 . 之變化的圖表。 天線元件10係高10mm、寬23mm、剖面為lmmx 1mm之銅(導 電率5.8xl07Simens/m)製品。電路基板2係長邊方向120mm、寬 )90 ，而材質為FR-4(比介電常數4.4、介質損耗因數 嘗接也圖案6係電路基板2上的銅落圖案，長邊方向113inm、 4盘二2電線8、接地線7、第1導體圖案3及第2導體圖案 及望1 j案6相同，係電路基板2上的銅細案。從供電線8 接點案3之連接點P1到接地線7及第1導體圖案3之連 ”為止的距離係2.5mm。電容器5的靜電電容為4.ipf。 =5可知’從接地線7及第i導體圖案3之連接點p2到電 ϋί止的距離γ較短時，如*記號所示，相對於上述微型環 ，式電、流，偶極模式電流具有支配性；使天線裝置1Α靠近導電 之連反之，從接地線7及第1導體圖案3 到電今器5為止的距離Υ較長時，如△記號所示，相 極赋錢’微親狀赋糕具妓錄；使天線裝置 葬近導電體20時’共振頻率會上升。例如，假定以雙面膠帶 =天線裝置1A細在雜之窗框而使用的情況時，電路基板2 ，，體2。的距離可設為lmm左右。此例中，如記號所示， -7.5mm時，微型環狀模式電流與偶極模式電流可達到平衡，而 使天線裝置1A靠近導電體20時的共振頻率之變化變小。 圖6係设計天線裝置1A時的流程圖。藉由依此流糊而設 針對尺寸關關4A所^:財的鱗裝置，也能設計成在導 電體靠近時的共振頻率之變化變小。 首先，決定電路基板2、接地圖案6、天線元件10等各部的 位置^尺寸’決定供電線8的位置(# 。其次，暫定接地線7及 電谷器5的位置(#2) ’並暫定電容器5的靜電電容(#3)。於此狀 態了，對於暫時組裝之天線裝置1A的輸入阻抗進行測定(#4)。 然後，將測定到之輸入阻抗值在史密斯圖(Smithehart)上製圖，判 斷阻抗之執跡是否通過史密斯圖的中央(#5)。阻抗之軌跡未通過 史密斯圖的中央時(#5為No)，改變接地線7的位置，亦即改變 從供電線8及第1導體圖案3之連接點？丨到接地線7及第丨導體 圖案3之連接點P2為止的距離X(#6)，並反複上述步驟。 阻抗之軌跡通過史密斯圖的中央時為Yes)，則接著判斷 1357690 的鱗(微觸狀天線11與轉料錄天線之功能 5 ί，6)之共振頻率是否與所希望的發射信號頻率&-致(# 致11之共振鮮與所希望的發射信魏率&不-ίί Λ的靜電電容(#8)，反複上述步驟。微型環狀 希望的發射信號頻率fr致時，例如於使 裝置ia假定為最靠近之距離的狀態下， ^壯Ϊ裝置1A雜人阻抗(#9)。從測定到之輸人阻抗，判斷 、曰裝置1A的天狀共振鮮是雜所希望之頻率產生偏移；或 者疋否即使產生偏移’而為可容許的範圍内（#1〇)。天線震置认 的天線之共振鮮觸希望之鮮大财生偏移時(㈣為 改變電容器5的位置，亦即改變從接地線7及第丨導體圖案3之 連接點P2到電容ϋ 5為止的距離γ(#11)，並反複上述步驟。依 如此所構成之第1實施形態的天線裝置1Α，於導電體靠近 振頻率的變化也會變小，能於所希望之發射信號頻率&抑制^ 的降低。 又，圖1中，供電線8及電容器5之間配置有接地線7 ;但也 可替換供電線8與接地線7的位置，於接地線7及電容器5之間 配置供電線8。又，可將微調電容器(trimmercapacit〇r)與電容器^ 並排地插入。此時，對於起因於零件性能之差異、零件之尺寸誤 φ 差、女裝之位置誤差等的共振頻率之偏移，可藉由調整微調電容 器的電容崎正。 又’為提高微型環狀天線11之增益，一般將環路的面積加大； 但由於设计性、攜帶性、施工性與其他限制，有時並無法加大環 路的面積。圖4A所示之具體實例中，天線元件1〇的剖面採 lmmxlmm的正方形，但並不限於此，也可因應所需而改變天線 元件10的剖面尺寸(例如，加大寬度到大於厚度）。藉此，可不用 加大環路的面積而提高增益。 或者’如圖7所示，也可將天線元件1〇的剖面之寬度加大， 並在天線元件10設置狹縫l〇a。又，圖7中，構成天線元件1〇之 面中，僅在平行於電路基板2的面設有狹縫i〇a，但也可在垂直於 $路ΐϊ2 置狹縫。如上所述’在天線元件10設置狹縫10a 中，比起L所-ϊί阻值增加，共振的Q值下降。因此，圖8 振頻率偏特雜天線的共 [第2實施形態] 第2ΪΙ^ΐϋ本ί明的天線裝置之第2實施形態。圖9顯示依 絲报能久=天線裝置1Β之結構。相較於依圖1所示的第1實 其線裝置1Α ’依第2實施形態的天線裝置m中，電路 面ΐ裝基板，各在電路基板2之第1面(例如表面)設置 電職板2之第2面(例如背面)設置其他之天線 。電路基板2的第1面侧之接合區2a及第2面側 2b，各以通孔電連接。 此w ,所述’藉由使用雙面安裝基板作為電路基板2，將微型環 ^ 1與電路基板2交叉而構成，能提高電路基板2之安裝密 又而達到天線裝置1B的小型化。又，在電路基板2的第i面或第 2 ^之任-_丨如衫2面)安裝高餘高之零斜，該安裝有高 f向零件之面(第2面)側的天線元件1G，之高度，可拉高到高於 ^-面(第丄面)側的天線元件1〇之高度。藉此，能抑制天線裝置 一的整體高度。如此一來，依第2實施形態，能有效活用高度較 尚之零件所形成的空間，將天線裝置1B薄型化。 [第3實施形態] 接著，說明本發明的天線裝置之第3實施形態。圖1〇顯示依 3,實施形態的天線裝置ic之結構。相較於依圖丨所示的第j實 施形態之天線裝置1A，依第3實施形態的天線裝置1C中，使用 輔助基板21以取代天線元件1〇，利用形成於電路基板2上的導體 圖案2c、形成於輔助基板21之一面(外面)的導體圖案21 與端面通孔2lc等’而構成微型環狀天線/卜 21b 、又，也可使用多層基板作為電路基板2及輔助基板21。此時， 構成微型環狀天線11之導體圖案2c、21a、21b等並非必須形成 1357690 於各基板的表面，也可形成於内層。又，圖10所示之結構例中， 將電容器5配置在辅助基板21上，但也可將電容器5配置在電路 基板2上。而且，供電線8與接地線7經由端面通孔2id連接到 輔助基板21的導體圖案21a ;但也可將供電線8與接地線7連 到電路基板2上的導體圖案2c。 如上所述，由於使用輔助基板21以取代易變形之天線元 10 ’而構成微型環狀天線11 ’故天線裝置lc對外力的耐久性提 高。因此’不僅有安裳在建築物之窗戶的防盜感測器之用途，也 可使用於加速度或被施加衝擊的移動體内部之無線通信等。When the high frequency signal is output from the wireless circuit unit 12, the high frequency current is excited by the antenna device 1A. As shown in FIG. 2, the high-frequency current can be divided into two: current (micro-ring mode current) Ιι' flows along the conductive circuit constituting the micro-ring antenna 11, contributing to the emission as the miniature loop antenna 11; (The dipole mode current melon flows in the longitudinal direction of the circuit board 2, contributing to the emission of the dipole antenna as the long-side direction of the circuit board 2. The micro-ring mode current I! along with the micro loop antenna The rectangular parallel direction formed by 11 'excites the radio wave of the polarized wave parallel to the micro annular surface (horizontal polarized wave component SH). On the other hand, the dipole mode current I2 follows the long side direction of the ground pattern 6 In the vertical direction, the radio wave (vertically polarized wave component Sv) of the polarized wave parallel to the longitudinal direction of the ground pattern 6 is excited. In the conventional antenna device using the micro loop antenna, only the micro loop antenna is focused on The horizontally polarized wave component excited by the micro-ring mode current h, and the impedance adjustment of the micro loop antenna is performed to maximize the amplitude of the horizontally polarized wave component. The vertical polarization excited by the dipole mode current I2 Wave component Ignore, or make adjustments to be as small as possible. 1357690 The characteristics of the transmitting signal frequency f and the input impedance of the antenna are not normal. L2' shows the ideal antenna characteristics for the transmitted signal frequency fQ. For the Y & The characteristics are such that the antenna gain is relative to the frequency of the transmitted signal f〇^green 2' due to part error or other reasons, as indicated by the dashed line in the figure, the upper and lower or/or left and right direction of the graph is offset. When the antenna characteristics are actually When the characteristics shown in the top , are at the transmission signal frequency fG, the antenna gain will be greatly reduced from the set value of the juice. Furthermore, we know that when the conductor and the antenna device are close, in the micro-ring day = dipole day _ In contrast, in Fig. 3B, the solid line age assumes no antenna characteristics when there is a component error. In this state, the antenna of the micro loop antenna is particularly close to the antenna device, such as a little chain line. Shown, there is a property of shifting to the graph side (resonance frequency rise). On the other hand, the ground plane pattern 6 forms an f-pole antenna, when the conductor is close to the antenna device, such as a two-point chain line It has the property of shifting to the left of the graph of 4 (the resonance frequency is lowered). In the present invention, the antenna antenna gain of the entire antenna device is maintained by utilizing the opposite nature of the micro loop antenna and the dipole antenna for the adjacent conductor. In other words, the antenna device 1A of the first embodiment shown in FIG. 1 has a micro mode, a current mode and a dipole mode. The current synthesized by the current flows, so when the conductive body is close, the effect of the resonance frequency of the micro-ring antenna is the same as that of the dipole antenna, and the effect of the frequency is offset. As a result, the variation of the resonance frequency is very small. The case where the wireless circuit unit 12 connected to the antenna (the micro-ring antenna U and the ground pattern 6 functioning as a dipole antenna) does not match can be prevented or reduced. Next, with respect to the antenna device 1A shown in FIG. 1, the specific size is designed as shown in FIG. 4A, and the finite element method (FEM, for the antenna device 1 is brought close to the conductor 2) as shown in FIG. 4B. Finite dement method) Perform numerical calculations. Fig. 5 is a graph showing changes in the resonance frequency of the antenna for the distance D between the circuit board 2 and the conductor 20. The antenna element 10 is a copper (conductivity 5.8 x 107 Simens/m) product having a height of 10 mm, a width of 23 mm, and a cross section of 1 mm x 1 mm. The circuit board 2 has a length of 120 mm and a width of 90, and the material is FR-4 (the dielectric constant is 4.4, the dielectric loss factor is also the pattern of the copper drop pattern on the 6-series circuit board 2, and the long-side direction is 113 inm, 4 discs. The second and second electric wires 8, the grounding wire 7, the first conductor pattern 3, the second conductor pattern, and the second conductor pattern 6 are the same as the copper thin film on the circuit board 2. From the connection point P1 of the power supply line 8 to the case 3 The distance from the connection between the ground line 7 and the first conductor pattern 3 is 2.5 mm. The capacitance of the capacitor 5 is 4.ipf. = 5, it is known that 'from the connection point p2 of the ground line 7 and the ith conductor pattern 3 to the power ϋ When the distance γ is short, as indicated by the * mark, the electric current, the current, and the dipole mode current are dominant with respect to the micro ring; the antenna device 1 is close to the conductive connection, and the ground line 7 and the first When the distance 导体 between the conductor pattern 3 and the electric current device 5 is long, as indicated by the △ mark, the phase is extremely rich, and the micro-friendly shape is recorded. When the antenna device is buried near the conductor 20, the resonance frequency rises. For example, assuming that the double-sided tape = the antenna device 1A is used in a complicated window frame, the circuit substrate 2, the body 2. The distance can be set to about 1 mm. In this example, as shown by the symbol, when the voltage is -7.5 mm, the micro-ring mode current and the dipole mode current can be balanced, and the resonance of the antenna device 1A close to the conductor 20 is obtained. Fig. 6 is a flow chart when the antenna device 1A is designed. By setting a scale device for size control 4A, it is also possible to design a resonance when the conductor is close. First, the position "size" of each of the circuit board 2, the ground pattern 6, and the antenna element 10 is determined to determine the position of the power supply line 8 (#. Next, the position of the tentative ground line 7 and the electric grid 5 is ( #2) 'The capacitance of the capacitor 5 is tentatively set (#3). In this state, the input impedance of the temporarily assembled antenna device 1A is measured (#4). Then, the measured input impedance value is in Smith chart. (Smithehart) on the drawing, to determine whether the impedance trace is through the center of the Smith chart (#5). When the impedance track does not pass through the center of the Smith chart (#5 is No), change the position of the ground line 7, that is, change from Connection point between the power supply line 8 and the first conductor pattern 3? The distance X (#6) from the connection point P2 of the ground line 7 and the second conductor pattern 3 is repeated. The impedance trajectory is Yes when passing through the center of the Smith chart, and then the scale of the 1357690 is determined (micro-touch) The resonance frequency of the antenna 11 and the transfer recording antenna 5 ί, 6) is the same as the desired transmission signal frequency &- (the resonance of ##11 is fresh and the desired transmission rate is & not -ίί Λ Electrostatic capacitance (#8), repeat the above steps. When the frequency of the desired circular emission signal of the micro-ring is fr, for example, in the state where the device ia is assumed to be the closest distance, the robust device 1A hybrid impedance (#9) ). From the measured input impedance, it is judged that the natural resonance of the 曰 device 1A is not disturbed by the desired frequency; or whether it is within the allowable range even if the offset is generated (#1〇). The resonance of the antenna that is oscillated by the antenna is freshly touched by the hope of the fresh wealth offset ((4) is to change the position of the capacitor 5, that is, to change from the connection point P2 of the ground line 7 and the second conductor pattern 3 to the capacitor ϋ 5 The distance γ (#11) is repeated, and the above-described steps are repeated. According to the antenna device 1 of the first embodiment configured as described above, the change in the frequency of the proximity of the conductor is also small, and the desired signal frequency & In addition, in FIG. 1, the ground line 7 is disposed between the power supply line 8 and the capacitor 5; however, the position of the power supply line 8 and the ground line 7 may be replaced, and the ground line 7 and the capacitor 5 may be disposed between the ground line 7 and the capacitor 5. Wire 8. In addition, a trimmer capacitor (trimmercapacit〇r) can be inserted side by side with the capacitor ^. At this time, the resonance frequency is caused by the difference in the performance of the part, the difference in the size of the part, and the position error of the dress. The shift can be adjusted by adjusting the capacitance of the trimmer capacitor. In order to increase the gain of the miniature loop antenna 11, the area of the loop is generally increased; however, due to design, portability, workability and other limitations, sometimes Can't increase the loop In the specific example shown in FIG. 4A, the cross section of the antenna element 1〇 adopts a square of 1 mm×1 mm, but is not limited thereto, and the cross-sectional size of the antenna element 10 may be changed as needed (for example, the width is increased to be larger than the thickness). Thereby, the gain can be increased without increasing the area of the loop. Or, as shown in Fig. 7, the width of the cross section of the antenna element 1〇 can be increased, and the slit 10a can be provided in the antenna element 10. Further, in Fig. 7, among the faces constituting the antenna element 1 狭缝, only the slit i 〇 a is provided on the surface parallel to the circuit board 2, but the slit may be formed perpendicular to the ΐϊ 2 as described above. In the case where the slit 10a is provided in the antenna element 10, the resistance value of L is decreased, and the Q value of the resonance is decreased. Therefore, the resonance frequency of the antenna is as shown in Fig. 8. [Second embodiment] 2nd ΪΙ^ΐϋ本The second embodiment of the antenna device of the present invention is shown in Fig. 9. Fig. 9 shows the structure of the antenna device 1 frame. The antenna device 1 according to the second embodiment is different from the first antenna device 1A shown in Fig. 1. In the circuit surface armor substrate, each of the first surface (for example, the surface) of the circuit board 2 is provided with an electric board 2 The other surface is provided on the second surface (for example, the back surface), and the junction region 2a and the second surface side 2b on the first surface side of the circuit board 2 are electrically connected by via holes. The substrate is used as the circuit board 2, and the micro-ring 1 and the circuit board 2 are formed to intersect each other, and the mounting of the circuit board 2 can be improved to reduce the size of the antenna device 1B. Further, the ith surface or the second surface of the circuit board 2 ^任任-_丨如衫2面) Install the high-inclination zero-angle, the height of the antenna element 1G on the side of the high-f-face (the second side) of the part, the height can be raised above ^- The height of the antenna element 1 on the side of the face (the second side). Thereby, the overall height of the antenna device 1 can be suppressed. As a result, according to the second embodiment, the space formed by the parts having a higher height can be effectively utilized, and the antenna device 1B can be made thinner. [Third embodiment] Next, a third embodiment of the antenna device of the present invention will be described. Fig. 1A shows the structure of an antenna device ic according to the third embodiment. In the antenna device 1A of the third embodiment, the antenna substrate 1C according to the third embodiment uses the auxiliary substrate 21 instead of the antenna element 1A, and the conductor pattern formed on the circuit substrate 2 is used. 2c, the conductor pattern 21 formed on one surface (outer surface) of the auxiliary substrate 21 and the end surface through hole 21c, etc. constitute a micro loop antenna/b 21b, and a multilayer substrate may be used as the circuit board 2 and the auxiliary board 21. At this time, the conductor patterns 2c, 21a, 21b and the like constituting the micro loop antenna 11 do not have to be formed 1357690 on the surface of each substrate, and may be formed on the inner layer. Further, in the configuration example shown in Fig. 10, the capacitor 5 is disposed on the auxiliary substrate 21. However, the capacitor 5 may be disposed on the circuit board 2. Further, the power supply line 8 and the ground line 7 are connected to the conductor pattern 21a of the auxiliary substrate 21 via the end surface through hole 2id; however, the power supply line 8 and the ground line 7 may be connected to the conductor pattern 2c on the circuit board 2. As described above, since the auxiliary antenna substrate 21 is used instead of the deformable antenna element 10' to constitute the micro loop antenna 11', the durability of the antenna device lc to the external force is improved. Therefore, not only the use of the anti-theft sensor of the window of the building, but also the wireless communication inside the moving body for acceleration or impact can be used.

The auxiliary substrates 21 and 22 are provided on both sides, and the micro-loop antenna u can be formed by using the conductor patterns 21a, 21b, 22a and the end surface through holes 21c, 22c and the like on the auxiliary substrates 21 and 21: This structure is formed on the circuit board 2 It is especially effective when mounting the substrate on both sides. [Fourth embodiment] Next, a fourth embodiment of the antenna device of the present invention will be described. Fig. 12 is a schematic view showing the configuration of an antenna device 1D according to the fourth embodiment. According to the antenna device 1D of the fourth embodiment, in any one of the antenna devices 1A, 1B, 丨匚, and ic of the above-described embodiments, the non-difficult outline casing 3 accommodating the vocation is further included; The wheel slanting shell 3G _ face, at least in contact with the micro loop antenna u conductor 31. It is predicted in advance that the antenna device 1D is attached to the window glass or the table, etc., and the micro-loop antenna is mounted on the surface of the window 3, etc. 11 is inserted into the conductor 3 to design the antenna device 1D, and the desired coplanarity is matched in this state. With such a configuration, in addition to the effects of the above-described third to third embodiment shapes g, and even if the antenna is mounted to the window glass, the table, and the wall 2, it is impossible to bribe the electric conductor 31 from the micro-wei antenna 11. Since the surface side does not depend on the material of the mounting surface, it can suppress the change of the resonance solution, and the transmission signal frequency can be suppressed to suppress the decrease of the antenna gain. Further, the ferrule housing 1357690 is shown as being inserted into the conductor 31 as shown in _12B. [Seventh Embodiment] Next, a seventh embodiment of the antenna apparatus according to the present invention will be described. The seventh embodiment is a wireless communication device using the antenna device according to any one of the first to sixth embodiments. In the past, a wireless communication device such as a remote control device for a home appliance device has been put into practical use. However, in a wireless communication device using infrared rays, although reflected waves due to a wall surface or a ceiling can be used, when there is an obstacle in the optical path between the transmitter (infrared LED) and the receiver (light receiving element), the infrared rays are blocked. Signal transmission and reception cannot be performed properly. Therefore, in recent years, a wireless communication device formed by radio waves of a specific small power wireless communication type (STD-T67 or the like) has been proposed. Fig. 15, Fig. 16A, Fig. 16B and Fig. 17 each show an example of a system for switching control and dimming control of a lighting device using a wireless communication device using any of the above-described antenna devices. In the example shown in Fig. 15, the transmitter 51 and the receiver 52 are each provided on the wall surface, and the receiver 52 is connected to the illumination device 50. The transmitter 51 is integrally formed with, for example, a human body sensor disposed on the porch. When the human body sensor detects the presence of the human body, a signal for lighting the illumination device 50 is transmitted from the transmitter 51 to the receiver 52. . The receiver 52 is provided integrally with, for example, a switch of the illumination device 50 provided on the wall surface. When receiving a signal from the transmitter 51, the illumination device 50 is turned on by the wiring provided on the back side of the wall surface. When the human body enters the room, sometimes it stops when the transmitter 51 and the receiver 52 are blocked. At this time, if the door is opened to the indoor side, there is an obstacle that is more shielded to the LED light. (larger area), in the wireless communication s using infrared rays, the signal from the transmitter 51 is not completely received by the receiver %, and the noble light of the illumination device 50 may be delayed. On the other hand, in the wireless communication formed by radio waves, even if there is a human body between the transmitter 51 and the receiver 52, since the k number from the transmitter 51 is actually received by the receiver 52, the swearing can be quickly set to 50. light. Figs. 16A and 16B each show an example of a system in which a wireless communication device using any of the above-described antenna devices is applied to switch control and dimming control of a makeup device. Fig. 16A is a cross-sectional side view of the dressing room viewed from the side; the figure is a perspective view of the dressing room facing the 12 1357690 and looking straight from the right obliquely upward. In the example shown in FIGS. 16A and 16B, the transmitter 51 is disposed on the wall surface of the make-up room, and the receiver % is formed with a light switch having an operation handle connected to the illumination device 50 and the switch operation illumination device 5〇, and It is located on the outer wall of the population of the dressing room. The transmitter 51 and the human system H (not shown) form a body * setting 'the ship's ship detector detects the presence of the human body, and transmits from the transmitter to the receiver 52 for causing the illumination device 5 to 134 lights of the radio wave money. When the receiver 52 receives a signal from the transmitter 51, it passes through the wiring provided on the back side of the wall (via an illumination control unit (not shown)), and the illumination device 3 is turned off because the human body enters the dressing room. Room: There is a door of the dressing room between the transmitter 51 and the receiver 52; if the wireless signal from the transmitter 51 is LED light, there will be no transmission of the receiver 52: However, the wireless formed by the radio wave In the communication, even if the transmitter 51 and the receiver are supported, 'because the radio wave signal from the transmitter 51 is actually received by the receiver 52, the illumination device 5 can be quickly turned on. Also, not limited: can also be applied to the closet. Since the door sill is also opened and closed in the closet in which the clothes are stored, the antenna device of the present invention is suitably used similarly to the makeup room. The transmitter 51 is provided in a remote control device operated by a user. The switch or the like of the wall illuminating device 50 is formed into a body or a device 5G. The user can operate the remote control device, ': adjust the dimming level (brightness) of the illumination device 5 to the desired level. This bit exhibits a wireless signal from the t-ray = radio waves, and the directionality of the transmitter 52 is directed toward the receiver, and the transmitter 51 is directed toward the device. The wireless remote control signal can be easily received by the receiver 52' so that the operability of the transmitter 51 can be improved. Zhongcang (4) 1 human body sensor or off, etc., requires the protrusion from the wall as above; !,, when the gold body is set as small as possible and thinned, however, ί can not be smoothly sent and received. In order to overcome this situation, it is generally preferred to think that: #由赖_状天线(四)波天_直13 1357690 is large, so that radio wave communication is established; as a result, the result is reduced from the wall surface = the amount of protrusion from the wall surface 'and The remote transceiver module for sensing the 11 or the shaft-body is not included in the metal box of the wall, so it is easy to be charged; ° _ ground' we cannot predict that the remote control device will It is used in the surrounding environment; when it is used close to a conductor such as a metal, there is a problem that the frequency characteristic shifts due to the ft!! conductor. However, according to the above-mentioned ith to sixth day, the device is caused by the electric conductor. The resonance frequency offset 汾a of the antenna is small, so that a positioning communication capability can be maintained. 1 mesh i, the antenna device disposed in the transmitter 51 and the receiver 52 described above does not necessarily have the same structure. It is necessary to use an antenna device of a different structure. That is, there is no antenna of the metal body in the vicinity of the use environment of the channel transmitter 51 or the receiver 52; it is known in advance that there is a metal in the vicinity of the use environment. Designed to pay for the 51st or the (4) 52 The antenna device of the present invention. ❿ This application is based on Japanese Patent Application No. 2〇〇7_132344, the contents of which are based on the specification and schema of the above-mentioned special fund application, and finally the combination of the cost application. 51 and the receiver 52 are not limited to one-to-one, and it is also possible to add a transmission to the receiver 52 having a plurality of transmitters 51. Further, the j sensor is disclosed as the transmitter 51; however, if the private information can be kept secret, It is not limited to the f-heat type, and the image processing type human body sensing with camera photography function can also be used as a type of the transmitter 51, and the timekeeping function can also be used, and after the elapse of time, A timer for transmitting radio waves at a predetermined time. Further, the invention of the present application is fully described with reference to the embodiments of the additional drawings; however, the invention of the present application is apparently carried out by those having ordinary knowledge in the art. Various modifications or variations are therefore made without departing from the scope of the invention. Of course, it is also within the technical scope of the invention of Ke. 1357690 [Simple description of the diagram] 1 is a perspective view showing a configuration of an antenna apparatus according to a first embodiment of the present invention.
