Field of the Invention The present invention relates to a dielectric composition, and more particularly, to a composite dielectric composition for an ultra-high frequency wave which is used as a core material for various high power radio communication components. In recent years, with the development of wireless communication such as mobile communication and satellite communication, the demand for communication has increased, and the utilization rate of microwave is also increasing due to expansion of digital communication. As a core part enabling the above-described microwave radio communication, a duplexer, a band pass filter, a voltage controlled oscillator, a flat antenna for a GPS (Global Positioning System), an LC- Chip filters, and each component is manufactured using a low-loss dielectric, a so-called 'high-frequency dielectric,' as its main material.

In other words, BaO (barium oxide) is generally used in a wireless communication part for high-power systems, pbO (lead oxide) based, Nd 2 O 3 (oxidation video rhodium) or Sm 2 O 3 (samarium oxide) type, TiO 2 (titanium oxide ) system and, a printing digital Mg (Ca) which is mainly used in the communication part TiO 3 (calcium magnesium titanate) type, (ZrSn) TiO 4 (zirconium tin titanate) systems and satellite seconds are generally used to for communication components loss A dielectric material, Ba (MgTa) O 3 (barium magnesium tantalate), is a typical high-frequency dielectric material already developed.
또한, 상기 초고자파용 유전체는 각종 고출력용 무선 통신 부품에 이용될 수 있도록 다음과 같은 유전 특성을 충족시키고 있다. 첫째, 높은 주파수 선택성을 위하여 높은 품질계수(1㎓에서 3000이상)를 가져야 하고, 둘째, 부품의 소형화를 위하여 높은 유전율(r＞20)을 가져야 하며, 셋째 회로의 온도 안정성을 위하여 공진주파수의 온도계수가 0을 기준으로 조절이 가능해야 한다.In addition, the dielectric material for ultra low frequency has the following dielectric properties so that it can be used for various high power radio communication components. First, for high frequency selectivity, it should have a high quality factor (more than 3000 at 1 GHz), and second, it should have a high dielectric constant r> 20). For the temperature stability of the third circuit, the temperature coefficient of the resonant frequency should be adjustable based on zero.
본 발명도 상기와 같이 높은 품질계수와 높은 유전율을 가지는 동시에 공진주파수의 온도계수의 안정되어 있어 고출력용 무선 통신 부품의 핵심 재료로 사용될 수 있는 초고주파용 복합 유전체 조성물을 제공함에 그 목적이 있다.The object of the present invention is to provide a composite dielectric composition for a microwave having a high quality factor and a high dielectric constant as described above, and a stable temperature coefficient of a resonance frequency, which can be used as a core material of a high-output wireless communication component.
