Abstract

The application provides a GNSS antenna, comprising: a ground plate; an inner ring-shaped radiator arranged above the ground plate, the inner ring-shaped radiator having a high-frequency working frequency band, the high-frequency working frequency band being 1560-1610 MHz; and an outer ring-shaped radiator arranged above the ground plate, the outer ring-shaped radiator being coaxial with the inner ring-shaped radiator and being arranged in a spaced manner to form a ring-shaped structure, the outer ring-shaped radiator having a low-frequency working frequency band, the low-frequency working frequency band being 1160-1300 MHz; and the inner ring-shaped radiator and the outer ring-shaped radiator both being center-symmetrical structures. The GNSS antenna provided by the application can realize wide-band coverage in a compact and simple structure, and can ensure high gain and good radiation performance in the whole working frequency band.
