1. a kind of high stable phase of microwave attenuation type, high-precision GNSS measurement type antenna, it is characterised in that the antenna includes covering of the fanCross-shaped oscillator, half opening cylindrical cavity, suppression diameter plate, microwave attenuation plate, guiding plate and polarization isolation work(sub-module;

  • Wherein,The half opening cylindrical cavity bottom central zones are provided with 4 support cylinder components, and the covering of the fan cross-shaped oscillator includes 4 listsFirst oscillator, each unit oscillator is installed on the top of a support cylinder, and keeps away from bottom of chamber with high;

    The conductor guiding plate is installed, the conductor guiding plate shakes with the covering of the fan cross at the top of the covering of the fan cross-shaped oscillatorSon passes through a coaxial insulating mounting of medium annulus;

    The suppression diameter plate spaced a predetermined distance and is coaxially installed on the bottom surface of half opening cylindrical cavity, and by support cylinder component withHalf opening cylindrical cavity keeps microwave ground potential;

    The microwave attenuation plate abuts and is arranged at the suppression diameter plate bottom surface;

    The suppression diameter plateIt is printed on respectively on microwave-medium plate with microwave attenuation plate, it is coaxial two-by-two to be mounted to an independent microwave module;

    The polarization isolation work(sub-module is arranged at the bottom of the microwave attenuation plate.
