Abstract

A bias beam occultation GNSS antenna disclosed by the present invention comprises an antenna unit, the antenna unit comprises a first layer dielectric plate, a second layer dielectric plate, a third layer dielectric plate, a fourth layer dielectric plate and a metal base plate, the first layer dielectric plate is printed with a first microstrip patch, the first layer dielectric plate is provided with a plated-through hole, and the second layer dielectric plate is printed with a second microstrip patch. A first microstrip patch is printed on the first dielectric plate, a second microstrip patch is printed on the second dielectric plate, a gap is formed in the second microstrip patch, a feed network is arranged on the third dielectric plate, and the fourth dielectric plate and the third dielectric plate are attached to form a strip line feed network. The first-layer dielectric plate, the second-layer dielectric plate, the metal bottom plate, the third-layer dielectric plate and the fourth-layer dielectric plate are sequentially stacked from top to bottom, the first-layer dielectric plate and the second-layer dielectric plate are arranged in an array mode, and each column of the first-layer dielectric plate and the second-layer dielectric plate are rotationally arranged at a fixed angle difference. According to the invention, antenna beam deflection is realized through a space phase shift method of rotating an array element angle. The cost is low and the environmental adaptability is good.

Description

technical field [0001] The invention relates to the field of space detection instruments, in particular to a partial-beam occultation GNSS (Global Navigation Satellite System, Global Navigation Satellite System) antenna. Background technique [0002] When the GNSS signal passes through the ionosphere and atmosphere and reaches the low-orbit satellite at the other end, due to the existence of the propagation medium and its gradient, additional time delay and bending will be generated. Using these additional time delay and bending information, based on certain assumptions Under certain conditions, the electron density of the ionosphere and the refractive index, temperature, density, and water vapor content of the lower atmosphere can be obtained by inversion. As an essential part of the spaceborne occultation detection system, the performance of the antenna directly affects the performance of the entire system. The atmospheric occultation antenna usually used for GNSS radio o...
