これらの無線通信機器は、使用周波数帯がそれぞれ異なり、一つのアンテナで兼用できず、各々が単独のアンテナを有している。 These wireless communication devices, different use frequency bands, respectively, can not be combined in a single antenna, each having a single antenna. これらの通信機器のアンテナは、各機器において占める大きさの割合が大きく、車載通信機器類の小型化の妨げとなっている。 Antenna of these communication devices, the ratio of the size occupied in each device is large and hinders downsizing of the vehicle-mounted communication equipment. 【0003】そこで、本発明者は、これらの通信機器のアンテナを一体にまとめた統合アンテナを種々試みた。 [0003] Therefore, the present inventors have variously attempted integrated antenna summarized integrated antennas of these communication devices.
統合アンテナを効果的なものとするには、個々のアンテナ部分の小型化と共に、一体化の容易性が求められる。 To integrate the antenna with effective, along with miniaturization of the individual antenna portions, ease of integration is required.
小型アンテナとしては、フィルムアンテナやパッチアンテナ等がある。 The small antenna, there is a film antenna or a patch antenna or the like. しかし、従来のこれらのアンテナは、いずれも材質の面から、小型化と一体化の両方の条件を満たすことが難しい。 However, these conventional antennas are both in terms of material, it is difficult satisfy both miniaturization and integration. 例えば、統合する個々のアンテナとして、パッチアンテナを考えたが、一般のパッチアンテナはセラミックスを誘電体として用いるため、一体化が難しい。 For example, the individual antennas to integrate, but considered a patch antenna, generally a patch antenna for using ceramic as a dielectric integrated is difficult. 誘電体としてセラミックスに代えて合成樹脂を用いると、一体化は容易であるが、誘電率が低いため、 If instead the ceramic using a synthetic resin as a dielectric, but integrated is easy, since the dielectric constant is low,
アンテナが大型化する。 Antenna is increased in size. また、シート状の平面アンテナを積層して用いることを考えたが、誘電体が合成樹脂であるため、小型化が難しい。 Although considered to be used by laminating a sheet-like planar antenna, since the dielectric body is a synthetic resin, it is difficult miniaturization. 【0004】合成樹脂の誘電性を高めた誘電性樹脂材料としては、高誘電率の無機繊維を配合したものが種々提案されている。 [0004] As the dielectric resin material with improved dielectric synthetic resin, obtained by blending the inorganic fibers having a high dielectric constant it has been proposed. しかし、繊維は異方性があるため、これを混入した場合、表面精度等の精度が出難く、また誘電特性についても異方性が生じる。 However, the fiber because of the anisotropy, when mixed with this, hardly out accuracy such as surface accuracy and anisotropy occurs also dielectric properties. 特に、薄いフィルムとした場合に、異方性の影響が大きく、位相のずれを招く恐れが生じるなど、アンテナとしての性能に影響が考えられる。 In particular, when a thin film, greatly affects the anisotropy, etc. may result in a phase shift occurs, is considered affect the performance of the antenna. 特に高周波用のアンテナでは、波長が短いことから、寸法精度等の要求が厳しく、このため、誘電体材料として繊維を混入したものでは、性能確保が難しい。 In particular, in the antenna for high frequency, because the wavelength is short, strict requirements, such as dimensional accuracy, and therefore, is obtained by mixing the fibers as the dielectric material, it is difficult ensure performance.
今日、自動車に搭載される通信機器は、高周波化の傾向にある。 Today, communication equipment mounted in a vehicle, there is a tendency of high frequency. また、無機繊維は、材料として高価であり、これを用いるとアンテナのコストが高くなる。 The inorganic fibers are expensive as the material, the cost of the antenna becomes high when using this. 【0005】この発明の目的は、周波数帯の異なる通信が行えて、小型化、高性能化、および低コスト化が図れる誘電性樹脂統合アンテナを提供することである。 An object of the invention is to perform the different communication frequency bands, size reduction, is to provide a high performance, and dielectric resin integrated antenna cost can be reduced. 【0006】 【課題を解決するための手段】この発明の誘電性樹脂統合アンテナは、互いに異なる周波数帯に対応した複数の周波数帯別アンテナ部分を有し、これら各周波数帯別アンテナ部分は誘電性樹脂複合材の誘電体と導体とで構成されて互いに一体に統合され、上記各周波数帯別アンテナ部分の上記誘電性樹脂複合材が、合成樹脂に誘電体無機粉末の充填材を配合したものである。 [0006] SUMMARY OF THE INVENTION The dielectric resin integrated antenna of the invention has a plurality of frequency bands by the antenna portions corresponding to the different frequency bands, different respective frequency band antenna portion dielectric integrated formed integrally with each other by a dielectric and a conductor of the resin composite material, in which the dielectric resin composite material of the respective frequency bands by the antenna portion was blended filler dielectric inorganic powder synthetic resin is there. この構成によると、誘電体として誘電性樹脂複合材を用いるため、複数のアンテナ部分の一体化が容易に行え、かつ合成樹脂の単独に比べて誘電率が高く、個々のアンテナ部分の小型化が図れる。 According to this configuration, since the use of dielectric resin composite material as the dielectric, the integration of a plurality of antenna portion is easily performed, and higher dielectric constant than the single synthetic resin, the miniaturization of the individual antenna portions achieved. このように、個々のアンテナ部分の小型化と共に、複数のアンテナ部分の一体化により、統合アンテナの全体の小型化が図れる。 Thus, the size of the individual antenna portions, by integration of a plurality of antenna portion, thereby the overall size of the integrated antenna. また、充填材は、粉末を用いるため、繊維を用いる場合と異なり、異方性が生じ難く、表面精度,寸法精度の確保が容易で、誘電特性の異方性も生じ難い。 Also, the filler for use powder, unlike the case of using the fiber, anisotropic hardly occurs, surface precision, is easy to ensure the dimensional accuracy, even less likely to occur anisotropic dielectric properties. そのため、誘電特性の異方性等によって位相のずれ等を招くことのない優れた特性のアンテナとできる。 Therefore, it an antenna having excellent characteristics without causing a shift of phase equivalence by anisotropic such dielectric properties. このように高性能化も可能になる。 In this way it becomes possible performance. また、 Also,
粉末は繊維に比べて低コストであるため、アンテナのコストも低減できる。 Since the powder is a low cost compared to the fibers, it can be reduced the cost of the antenna. 【0007】この発明において、上記各周波数帯別アンテナ部分を、板状またはシート状とし、これら各周波数帯別アンテナ部分を積層状態に統合しても良い。 [0007] In the present invention, the respective frequency bands by the antenna portion, and a plate-like or sheet-like, may be integrated each of these frequency bands by the antenna portion in the stacked state. 各周波数帯別アンテナ部分は、誘電性樹脂複合材の誘電率が互いに異なるものとする。 Each frequency band by the antenna portion shall dielectric constant of the dielectric resin composite material are different from each other. このように積層することで、複数のアンテナ部分の一体化が容易に行える。 By stacking in this way, it allows the easy integration of multiple antenna portion. また、個々の周波数帯別アンテナ部分は、誘電率が互いに異なるものとするため、周波数帯が大きく異なっていても、各周波数帯別アンテナパターンの寸法差を小さくできる。 Also, the individual frequency band by the antenna portion, to shall dielectric constant different from each other, even when the frequency band is very different, it is possible to reduce the size difference of each frequency band by the antenna pattern. 【0008】この発明において、上記各周波数帯別アンテナ部分がパッチアンテナであっても良い。 [0008] In the present invention, each of the frequency band by the antenna part may be a patch antenna. この場合に、各周波数帯別アンテナ部分は誘電性樹脂複合材からなる誘電体の誘電率が互いに異なるものとする。 In this case, each frequency band by the antenna portion shall dielectric constant of the dielectric comprising a dielectric resin composite material are different from each other. これら各周波数帯別アンテナ部分は、例えば平面的に並ぶように統合する。 Each of these frequency bands by the antenna portion is integrated as for example arranged in a plane. 周波数帯別アンテナ部分をパッチアンテナとし、平面的に並べると、各周波数帯別アンテナ部分の一体化が容易に行える。 The frequency band by the antenna portion and the patch antenna, Arranging in plan, facilitates integration of each frequency band by the antenna portion. 例えば2色成形や3色成形等のように、同じ金型内で射出成形する方法や、個々の周波数帯別アンテナ部分を熱融着や超音波融着等で溶融接着する方法で、容易に一体化が行える。 For example, as such as a two-color molding or three-color molding, a method of injection molding in the same mold, a method of melt bonding the individual frequency band by the antenna portion by thermal fusion or ultrasonic fusion or the like, easily integration can be performed. 各周波数帯別アンテナ部分は、誘電性樹脂複合材の誘電率が互いに異なるものとするため、いずれの周波数帯のアンテナ部分も互いに同じ厚みに、かつアンテナパターンの寸法差を小さくでき、一体の平面的な統合アンテナとできる。 Each frequency band by the antenna portion, to shall dielectric constant of the dielectric resin composite material are different from each other, the antenna portion is also the same thickness from each other in any frequency band, and can reduce the size difference of the antenna pattern, the plane of the integral can the integration antenna. 【0009】各周波数帯別アンテナ部分をパッチアンテナとする場合に、各周波数帯別アンテナ部分の誘電性樹脂複合材からなる誘電体の厚さが互いに異なるものとし、これら各周波数帯別アンテナ部分が平面的に並ぶように統合しても良い。 [0009] In the case of the patch antenna of each frequency band by the antenna portion, the thickness of the dielectric of dielectric resin composite material is different from one another in each frequency band by the antenna portion, the respective frequency bands by the antenna portion it may be integrated so as to be aligned in a plane. このように厚さを変えると、同じ誘電率の誘電性樹脂複合材を用いることができて、製造が容易であり、より低コスト化が図れる。 With such change the thickness, and can be used a dielectric resin composite material of the same dielectric constant, is easy to manufacture, and more cost reduction can be achieved. 【0010】この発明の上記各構成の場合に、上記合成樹脂は熱可塑性樹脂とし、上記誘電性樹脂複合材は、射出形成、押し出し成形、または圧縮成形等の溶融成形が可能なものとすることが好ましい。 [0010] When the above configuration of the present invention, the synthetic resin is a thermoplastic resin, the dielectric resin composite, injection molding, be made capable of melt molding such as extrusion molding, or compression molding It is preferred. このような材質の誘電性樹脂複合材を用いることにより、溶融成形により、 By using a dielectric resin composite material of such a material, by melt molding,
誘電性樹脂統合アンテナを希望の形状に簡単に成形することができる。 A dielectric resin integrated antenna can be easily molded into the desired shape. 【0011】上記誘電体無機粉末の充填材は、誘電率が20以上でかつ誘電正接が0.005以下の誘電セラミックス粉であり、上記誘電性樹脂複合材は、この充填材を10〜40容量%配合したものであっても良い。 [0011] The dielectric inorganic powder filler is, and dielectric loss tangent at a dielectric constant of 20 or more is 0.005 or less in the dielectric ceramic powder, the dielectric resin composite, the filler 10 to 40 volume % may be obtained by blending. 充填材は、アンテナの小型化のためには、なるべく誘電率が高く、かつ無効成分となる誘電正接(Tanδ)については小さいほど良い。 Filler, in order to reduce the size of the antenna is as high as possible dielectric constant, and better less about reactive component to become the dielectric loss tangent (Tan?). 上記誘電率が20以上でかつ誘電正接が0.005以下という値は、誘電セラミックス粉として一般に得られる中で、優れた値である。 The dielectric constant value of and dielectric loss tangent at 20 or higher than 0.005, among which is obtained generally as a dielectric ceramic powder is an excellent value. 充填材の配合比率は、多いほど誘電性樹脂複合材の誘電率を高くできるが、多すぎると成形性が悪くなる。 Mixing ratio of the filler is enough to increase the dielectric constant of the dielectric resin composite material often, too moldability is deteriorated. 上記の誘電率および誘電正接を持つ誘電セラミックス粉を充填材として用い、上記配合量とすると、誘電性樹脂複合材として、例えば誘電率が5〜15程度で、誘電正接が0.0 Additional dielectric constant and using a dielectric ceramic powder having a dielectric loss tangent as a filler, if the above amount, as a dielectric resin composite material, for example, a dielectric constant of about 5 to 15, the dielectric loss tangent 0.0
008〜0.003程度のものができる。 It is of the order of 008 to 0.003. この誘電率および誘電正接の値は、フィルムアンテナとして優れたものとなる。 The value of the dielectric constant and dielectric loss tangent, and excellent as a film antenna. また、充填材の配合量が40%以下であると、誘電性樹脂複合材の成形性にも優れる。 Further, the amount of the filler is 40% or less, excellent in formability of the dielectric resin composite material. 【0012】上記誘電セラミックス粉の充填材は、未完全焼結体としても良い。 [0012] The dielectric ceramic powder filler may be incomplete sinter. 高誘電セラミックスは、焼結して初めて、優れた誘電特性が得られる。 High dielectric ceramics, only after sintering, resulting excellent dielectric properties. しかし、完全な焼結体としなくても、仮焼と言われるように、実際の焼結温度よりも少し低い温度で、完全に固まらないところで一旦焼結したものであっても、つまり未完全焼結体であっても、優れた誘電特性を得ることができる。 However, even without a complete sintered body, as is said to be calcined, the actual temperature slightly lower than the sintering temperature, even those that were once sintered in place that does not harden completely, that is unfinished burned down even sintered body, it is possible to obtain excellent dielectric properties. 【0013】 【発明の実施の形態】この発明の第1の実施形態を図1 DETAILED DESCRIPTION OF THE INVENTION The first embodiment of the present invention FIG. 1
