以往，在通訊機器中，為了使天線的共振頻率複共振化，提案一使用具備放射電極及介電質塊的天線、開關，控制電壓源之天線裝置。 Conventionally, in a communication device, in order to resonate the resonance frequency of an antenna, an antenna device that controls a voltage source using an antenna and a switch including a radiation electrode and a dielectric block is proposed.
例如，利用介電質塊的以往技術，在專利文獻1是提案一將放射電極形成樹脂模製體，再以接著劑來使介電質塊一體化，藉此取得高效率的複合天線。 For example, in the prior art of the dielectric material block, Patent Document 1 proposes to form a high-efficiency composite antenna by forming a resin molded body of a radiation electrode and integrating the dielectric mass with an adhesive.
又，使用開關，控制電壓源的以往技術，在專利文獻2是提案一具備第1放射電極、第2放射電極、及設在第1放射電極的途中部及第2放射電極的基端部之間，用以使第2放射電極與第1放射電極電性連接或切斷的開關之線裝置。 In addition, in the prior art, a first radiation electrode, a second radiation electrode, and a middle portion of the first radiation electrode and a base end portion of the second radiation electrode are provided in the prior art.

[專利文獻2]日本特開2010-166287號公報 [Patent Document 2] Japanese Patent Laid-Open Publication No. 2010-166287
然而，在上述以往的技術中也有以下的課題存在。 However, the above conventional techniques also have the following problems.
亦即，在專利文獻1所記載那樣的介電質塊的技術是使用激振放射電極的介電質塊，需要按每個機器設計介電質塊、放射電極圖案等，依其設計條件，而有天線性能劣化，或不安定要素增加的不良情形。 In other words, the technique of the dielectric mass as described in Patent Document 1 is to use a dielectric mass that excites the radiation electrode, and it is necessary to design a dielectric mass or a radiation electrode pattern for each device, depending on the design conditions. There is a problem that the performance of the antenna is degraded, or the unstable elements are increased.
又，由於放射電極被形成於樹脂模製體的表面，因此需要在樹脂模製體上設計放射電極圖案，需要按照安裝的通訊機器或其用途來天線設計、金屬模具設計，導致大幅度的成本增大。又，由於以接著劑來使介電質塊與樹脂模製體一體化，因此接著劑的Q值以外也會依接著條件(接著劑的厚度、接著面積等)，而有天線性能劣化，或不安定要素增加的不良情形。 Further, since the radiation electrode is formed on the surface of the resin molded body, it is necessary to design the radiation electrode pattern on the resin molded body, and it is necessary to design the antenna and the metal mold according to the mounted communication device or its use, resulting in a large cost. Increase. Further, since the dielectric mass is integrated with the resin molded body by the adhesive, the antenna performance is deteriorated depending on the bonding conditions (thickness of the adhesive, the subsequent area, etc.) in addition to the Q value of the adhesive, or Bad circumstances in which the factors of instability are increased.
並且，像在專利文獻2記載那樣使用開關，控制電壓源的天線裝置時，為了以開關來進行共振頻率的切換，而需要控制電壓源的構成或電抗電路等，天線構成會按機器而複雜化，無設計的自由度，有難容易調整天線的問題。 In addition, when the antenna device of the voltage source is controlled by using a switch as described in Patent Document 2, in order to switch the resonance frequency by the switch, it is necessary to control the configuration of the voltage source or the reactance circuit, and the antenna configuration is complicated by the device. There is no design freedom, and it is difficult to adjust the antenna easily.
本發明是有鑑於前述的課題而研發者，其目的是在於提供一種可彈性調整複共振化後的各共振頻率，可便宜且容易地確保對應於用途或每個機器的天線性能， 且可小型化或薄型化之天線裝置。 The present invention has been made in view of the above problems, and an object of the present invention is to provide an elastic frequency-adjustable resonant frequency of each resonance, which can inexpensively and easily ensure antenna performance corresponding to use or each machine.

而且，對於各共振頻率，可利用第3被動元件P3來彈性地進行最終的阻抗調整。 Further, for each resonance frequency, the final impedance adjustment can be elastically performed by the third passive element P3.
因此，第1共振頻率f1是主要在以圖4中的虛線A1所包圍的部分被調整。 Therefore, the first resonance frequency f1 is mainly adjusted in a portion surrounded by the broken line A1 in Fig. 4 .
又，第2共振頻率f2是主要在以圖4中的虛線A2所 包圍的部分被調整。 Further, the second resonance frequency f2 is mainly at the broken line A2 in Fig. 4 The enclosed part is adjusted.

又，由於第1輔助天線部6及第2輔助天線部7是以可撓性的薄膜導體形成且被折返，因此可適當變更第1及第2輔助天線部6，7與基板本體2的間隔，即使在設置處的間隙變化時或必須使第1及第2輔助天線部6，7彎曲而配置時，還是可彈性地對應於所安裝的框體的配置條件。特別是在第1及第2輔助天線部6，7不安裝天線元件AT或被動元件，只在基板本體2側安裝該等，可充分地確保第1及第2輔助天線部6，7的可撓性。 Further, since the first auxiliary antenna unit 6 and the second auxiliary antenna unit 7 are formed of a flexible thin film conductor and are folded back, the interval between the first and second auxiliary antenna portions 6 and 7 and the substrate main body 2 can be appropriately changed. Even when the gap at the installation is changed or the first and second auxiliary antenna portions 6, 7 must be bent and arranged, it is possible to elastically correspond to the arrangement condition of the mounted casing. In particular, the first and second auxiliary antenna portions 6, 7 are not provided with the antenna element AT or the passive element, and the first and second auxiliary antenna portions 6 and 7 can be sufficiently ensured only by attaching the antenna element AT or the passive element to the substrate main body 2 side. flexibility.

The size of the antenna element AT of the dielectric antenna can be reduced and the performance can be improved. Moreover, the cost incurred by the metal mold, design change, and the like is not required, and low cost can be achieved.
又，由於第1輔助天線部6及第2輔助天線部7是在絕緣性薄膜以金屬箔形成圖案，因此可取得高的可撓性，且適當選擇高的介電常數者作為絕緣性薄膜的材料，藉此可取得第1及第2輔助天線部6，7的圖案縮短效果，且所望的頻帶低時或被要求更小型化時也可對應。而且，可利用泛用的可撓性印刷基板，可謀求成本的低減。 In addition, since the first auxiliary antenna unit 6 and the second auxiliary antenna unit 7 are patterned in a metal foil on the insulating film, high flexibility can be obtained, and a high dielectric constant is appropriately selected as the insulating film. The material can thereby obtain the pattern shortening effect of the first and second auxiliary antenna portions 6, 7 and can also be used when the desired frequency band is low or when it is required to be more compact. Further, it is possible to use a general-purpose flexible printed circuit board, and it is possible to reduce the cost.
又，由於第1輔助天線部6及第2輔助天線部7的開放端是彼此朝相反方向配置，因此彼此的阻抗高的部分彼此間會成逆向，可抑制結合，且可有效地利用彼此間所產生的浮遊電容。 Further, since the open ends of the first auxiliary antenna unit 6 and the second auxiliary antenna unit 7 are arranged in opposite directions to each other, the portions having high impedances are reversed from each other, and the combination can be suppressed, and the mutual use can be effectively utilized. The resulting floating capacitance.
又，由於第1輔助天線部6的開放端對於天線元件AT的開放端是朝相反方向配置，因此彼此的阻抗高的部分彼此間會成逆向，可抑制結合，且可有效地利用彼此間所產生的浮遊電容。 Further, since the open end of the first auxiliary antenna unit 6 is disposed in the opposite direction to the open end of the antenna element AT, the portions having high impedances are reversed from each other, and the combination can be suppressed, and the mutual use can be effectively utilized. The resulting floating capacitance.
又，由於在第1輔助天線部6及第2輔助天線部7與基板本體2之間設置有間隔物8，因此可藉由設 定成所定厚度的間隔物8來將第1及第2輔助天線部6，7與基板本體2的間隔保持於一定。並且，藉由將間隔物8的材料設為高介電質材料，可取得第1及第2輔助天線部6，7的圖案縮短效果。而且，藉由採用橡膠等的彈性材料，亦可取得衝撃吸收效果。 Further, since the spacers 8 are provided between the first auxiliary antenna unit 6 and the second auxiliary antenna unit 7 and the substrate main body 2, it is possible to provide The spacer 8 having a predetermined thickness is fixed to keep the interval between the first and second auxiliary antenna portions 6, 7 and the substrate main body 2 constant. Further, by setting the material of the spacer 8 to a high dielectric material, the pattern shortening effect of the first and second auxiliary antenna portions 6, 7 can be obtained. Further, by using an elastic material such as rubber, a flushing and absorbing effect can be obtained.

並且，在垂直配置而將間隔物8的厚度設為6mm時(圖8的(c))是將間隔物8設置於基板本體2的端邊附近，圖1的天線元件AT的右側。 Further, when the thickness of the spacer 8 is set to 6 mm in the vertical direction ((c) of FIG. 8), the spacer 8 is provided in the vicinity of the end side of the substrate main body 2, and the right side of the antenna element AT of FIG.
由此結果可知，對於各配置，共振頻率是被抑制於900/1800MHz頻帶皆±1%程度的些微變化，第1及第2輔助天線部的配置所帶的頻率變動少，容易對應所安裝的每個機器。 As a result, it is understood that the resonance frequency is suppressed to a slight variation of about ±1% in the 900/1800 MHz band for each arrangement, and the frequency variation of the arrangement of the first and second auxiliary antenna sections is small, and it is easy to cope with the installation. Every machine.
另外，本發明並非限於上述實施形態及實施例，亦可在不脫離本發明的主旨範圍內實施各種的變更。 The present invention is not limited to the above-described embodiments and examples, and various modifications may be made without departing from the spirit and scope of the invention.
例如，上述實施形態是在第2延伸部設置天線元件，但即使在第4延伸部亦設天線元件也無妨。此情況，可藉由第4延伸部的天線元件來縮短第2元素的長度，適於天線佔有面積窄的情況等。並且，藉由對第4延伸部之天線元件的採用，亦可取得大的浮遊電容Ca。 For example, in the above embodiment, the antenna element is provided in the second extension portion, but the antenna element may be provided even in the fourth extension portion. In this case, the length of the second element can be shortened by the antenna element of the fourth extension portion, and it is suitable for a case where the antenna occupation area is narrow. Further, by using the antenna element of the fourth extension portion, a large floating capacitance Ca can be obtained.
而且，像上述實施形態那樣利用可撓性印刷基板來設置第1及第2輔助天線部為理想，但即使以其他可撓性的導體薄膜來形成也無妨。例如，即使使用具有可撓性的薄型的玻璃環氧基板在其上以銅箔等的金屬箔來形成第1及第2輔助天線部圖案也無妨。 Further, it is preferable to provide the first and second auxiliary antenna portions by the flexible printed circuit board as in the above-described embodiment, but it may be formed by using another flexible conductive film. For example, even if a thin glass epoxy substrate having flexibility is used, the first and second auxiliary antenna portion patterns may be formed by a metal foil such as copper foil.
並且，上述實施形態是將設置第1及第2輔助天線部的可撓性印刷基板安裝於間隔物上而設置在基板本體上方，但其他例如圖10所示般，不使用間隔物，以接著劑或雙面膠帶等來將設置第1及第2輔助天線部6，7的可撓性印刷基板貼附於內藏有天線裝置的通訊機器等的框體20的內面，藉此設置成延伸至基板本體2上方也無妨。 Further, in the above-described embodiment, the flexible printed circuit board on which the first and second auxiliary antenna portions are provided is mounted on the spacer and is disposed above the substrate body. However, as shown in FIG. 10, for example, no spacer is used, and then The flexible printed circuit board on which the first and second auxiliary antenna portions 6 and 7 are provided is attached to the inner surface of the casing 20 of the communication device or the like in which the antenna device is housed, by using a double-sided tape or the like. It is also possible to extend above the substrate body 2.
