Abstract

An antenna device comprises a reflecting plate, a top shielding cover arranged on one side of the reflecting plate, a first frequency band feed network, a substrate, a first frequency band radiating face, a first frequency band medium layer, a second frequency band radiating face, a second frequency band medium layer, at least one first frequency band feed probe, a second frequency band feed probe, a second frequency band feed network arranged on the other side of the reflecting plate and a low-noise amplifying circuit. The top shielding cover is fixed on the substrate, the first frequency band radiating face is connected to the first frequency band feed network through the first frequency band feed probe, the second frequency band radiating face is larger than the first frequency band radiating face and positioned on the second frequency band medium layer, the second frequency band radiating face is connected to the second frequency band feed network through a second frequency band feed probe, and the first frequency band feed network and the second frequency band feed network are connected with the low-noise amplifying circuit. The invention further provides a receiving system. By means of the antenna device and the receiving system, mutual interference between all frequency points is avoided, the phase stability of an antenna is improved, and the measuring accuracy is improved.

Description

technical field [0001] The invention relates to the field of satellite antennas, in particular to a novel feeding antenna device and a receiving system. Background technique [0002] With the continuous development of satellite navigation and measurement technology, satellite positioning system has also been widely used. At present, many countries around the world have established their own satellite positioning systems, such as China's Beidou system BDS, the United States' GPS system, Russia's GLONASS system, and Europe's Galileo GALILEO system. [0003] As the key equipment for satellite signal reception, the antenna has gradually matured. With the continuous maturity of these satellite systems and the deepening of the civilian application process, high performance has become the object pursued by consumers. [0004] Chinese Patent Publication No. CN202503105U discloses a measurement-type GNSS receiving antenna, which can effectively improve beam bandwidth, axial ratio ba...
