Technical field
What the present invention relates to is a kind of microwave composite material of ceramic base, the microwave composite material that specifically is a kind of ceramic-base high-molecular form reaches by its components and parts shape product of making that is used for microwave or cableless communication, its characteristics are to adjust and to obtain meeting the material and/or the components and parts goods of the range of frequency of service requirements in the wide frequency ranges of 0.1-30GHz, and under the prerequisite that does not increase product substrate thickness, can make the specific inductivity can be, and significantly increase amplitude of bandwidth up to 50.
Background technology
Along with the fast development of highly integrated, the subminiaturization and the transmitting high speedization of electronics, also impel microwave communication, microwave device and Microwave Net accordingly to the development and the fast development of ultralight, extra small and ultra-thin direction.Traditional microwave-medium base material commonly used has forms such as microwave-medium ceramics and dielectric materials base material.Wherein microwave-medium ceramics be with purity be 99.99% pottery behind high temperature sintering, make substrate at metals such as surface-coated chromium and copper again.Though it can have high dielectric constant and low-loss characteristics, the manufacturing process complexity, and matter is crisp firmly, and difficulty of processing is big, costs an arm and a leg.Dielectric materials class base material is to mix with tetrafluoroethylene after hot-forming and be laminated with copper sheet and form with titanium dioxide, barium titanate or strontium titanate.Be characterized in certain specific inductivity, but specific inductivity is usually less than 15, and the dielectric parameter on the substrate also often has anisotropic problem, the frequency band of goods such as the antenna that is made into is very narrow; Though its processing is relatively easy, quality is crisp firmly too.Directly with tetrafluoroethylene or polystyrene as dielectric substrate, though processing is convenient, its specific inductivity is 2～3 only, the geometrical dimension that causes making behind the electron device is too big, thereby it only can be applicable to the communications service on some ground.
In the reported in literature of relevant microwave material, U.S. Patent number US 5,922,435 and US 5,936,025 disclose a kind of shock-resistant dielectric materials that can be used as guided missile microwave wireless shielding modulator material respectively, are by TiO 2Powder mixes institute with polyureas and isocyanates superpolymer and becomes, and its specific inductivity is about 10, and dielectric loss factor is about 0.03-0.1.In the document of U.S. Patent number US 5,552,210, disclose a kind of be used to produce microwave wire contain Ti, Al, Mg 2O 3On the polymer-based carbon pottery of mineral compound, this matrix material is made up of the thermoplasticity or the thermosetting resin of the stupalith of filling more than one at least.In the document of european patent number EP 1,041,051, also disclose a kind of organically-modified stupalith, but its specific inductivity is little based on Ba base glass.Have report at present and use these above-mentioned microwave-medium base materials, can remain on 10 for making its dielectric loss tg δ -3-10 -4Low scope in, its DIELECTRIC CONSTANT ' generally all less, only be 2.5-25.As will obviously improving specific inductivity, can only be that cost realizes to increase its dielectric loss usually.In addition, publication number is that the Chinese patent literature of CN1267893A also discloses a kind of polymer magnetic polymer base material material of being made up of jointly the metal complexes and the thermoplastic resin material of metal organo-metallic material composition and small molecules glycol, diamines, diamino, two hydrazines or dioxime.Its still suspicion complexity on synthetic and manufacturing process of discovery in the practice, and when widening frequency band, yet existence can cause the loss increase of goods and the tendency that gain reduces.
