Abstract
The utility model relates to the application in satellite navigation field. At present, satellite navigation signal receiver antenna do not adopt the mode that Big Dipper, GPS and GLOONASS antennae output three satellite navigation signals by using one output port. The utility model provides a community antenna with one-way output for a satellite navigation receiver, and aims to solve the problemsthat navigation systems in Big Dipper areas and GPS and GLOONASS global navigation systems can not share antennae, and output by one way. The utility model adopts the technical solution that two microstrip antenna receiving plates are installed in the rectangular antenna, and respectively receive Big Dipper, GPS and GLOONASS satellite navigation signals, a low-noise amplifying circuit enlarges the received satellite navigation signals in two ways, and the three satellite navigation signals are input to a frequency combiner which is provided with a 50-ohm output port, and are sent to the satellite navigation receiver for use.
Description
The utility model antenna can be done the reception of satellite navigation field signal, especially can use a delivery outlet to receive the satellite navigation signals of three kinds of different systems of BD/GPS/GLOONASS simultaneously.
Background technology
At present, known satellite navigation signals reception antenna is the mode that adopts single Big Dipper, single GPS, single GLOONASS or the output of GPS+GLOONASS single channel, or the Big Dipper adds the GPS/GLOONASS two-way way of output, also do not have the document proof that the Big Dipper is added GPS and adds the GLOONASS antenna is exported three kinds of satellite navigation signals with a delivery outlet mode.
Summary of the invention
The problem of can not common antenna in order to solve existing Big Dipper RNAV system and GPS, GLOONASS Global Navigation System, can not a shared bars output cable, the utility model provides a kind of three kinds of satellite navigation signals is integrated, and single channel output is used for satellite navigation receiver.
The technical scheme that its technical problem that solves the utility model adopts is: on the substrate in the squaerial cover, two microstrip antenna dash receivers are installed, receive Beidou satellite navigation signal and GPS/GLOONASS satellite navigation signals respectively, the satellite navigation signals that is received is divided that two-way amplifies, filtering with low noise amplifier circuit.Then with Beidou satellite navigation signal and GPS/GLOONASS satellite navigation signals incoming frequency mixer, three kinds of satellite navigation signals are integrated, one 50 Ω output port is set, and is that the radio frequency cable of 50 Ω sends satellite navigation receiver to by characteristic impedance.
The beneficial effects of the utility model are: 1, simplified structure, dwindle the volume of the receiving antenna of satellite navigation; 2, signal is integrated, reduces and disturbs; 3, make things convenient for setting up of circuit; 4, reduce the quantity of satellite navigation receiver internal radio frequency socket, make that receiver internal components, cable reduce, the receiver outward appearance is neat, attractive in appearance, it is more convenient to install; 5, every receiver can be saved 30～100 meters long, that price is very high radio frequency cables, significantly reduces cost.
