Composite material of microstrip antenna substrate, preparation method and application
The invention discloses a composite material of a microstrip antenna substrate and a preparation method and application thereof. A main phase of the material is Co2Y type hexagonal ferrite with the mass fraction of 40-60%, an auxiliary material is pma organic glass microspheres with the particle size of 1-2 microns, the pma organic glass microspheres are compounded according to the mass fraction of 40-60%, and the preparation method comprises the following steps: 1) proportioning, primary ball milling and mixing, and drying; and 2) pre-sintering. And 3) secondary ball milling and drying. And 4) mixing the materials in a mortar according to the ratio, adding 20% of pva, pressing into a ring, and bonding at 180-220 DEG C. The prepared composite material has relatively low magnetic loss and dielectric loss at 1M-1GHz and frequency bands required by GPS and Bluetooth, and the gain and return loss of the simulated antenna substrate are better than those of the antenna substrate made of the existing FR4 material. Meanwhile, the preparation method is simple, the process is relatively short, and the bonding temperature required by a sample is relatively low.
本发明公开了一种微带天线基板的复合材料及制备方法、应用。材料主相为质量分数为40％‑60％的Co2Y型六角铁氧体，辅助材料采用粒径为1μm‑2μm的pmma有机玻璃微球，按照质量分数为40％‑60％复合，制备方法包括:1)配料，一次球磨混合，烘干。2)预烧。3)二次球磨，烘干。4)研钵中按配比混料，并加入20％pva后压环，180℃‑220℃黏结。所制备的复合材料在1M‑1GHz及在GPS和蓝牙所需频段有较低的磁损耗和介电损耗，仿真出的天线基板的增益及回波损耗比现有的FR4材料所做成的天线基板好。同时其制备方法简单，过程较短，样品所需黏结温度较低。
