Patent ID: 11799203

Abstract:
A modified-material-based high-precision combined antenna for satellite navigation and communications includes a high-frequency satellite navigation antenna metal radiating surface, a low-frequency satellite navigation antenna metal radiating surface, a WIFI/Bluetooth antenna metal radiating surface, a PCB, a shielding metal cavity and an injection molded modified-material-based substrate. The low-frequency satellite navigation antenna metal radiating surface is located between the high-frequency satellite navigation antenna metal radiating surface and the PCB. The WIFI/Bluetooth antenna metal radiating surface is located on a side of the low-frequency satellite navigation antenna metal radiating surface. The injection molded modified-material-based substrate is made of polyphenyl ether doped with a modified material, and the modified material has a relative permittivity of 2.65 and a density of 1.06 g/cm3. The injection molded modified-material-based substrate includes a first injection molded modified-material-based substrate and a second injection molded modified-material-based substrate.
