Problems solved by technology

[0002] Navigator is a product of modern technology, generally used for car and ship navigation. It is a kind of smart map, and can update the map data in it. At the same time, it can be used as a guide to prompt the driving route during use. Now some navigation The instrument uses the global satellite positioning and communication system independently developed by my country - the Beidou satellite navigation system. The working principle of its global positioning is to form a communication between the navigator and the navigation satellite, but buildings and metals will have certain influence on the navigation signal. At the same time, because of the small size of the navigator, its antenna is small and its ability to receive navigation signals is limited. Therefore, star loss or drift may occur in some environments

Abstract

The invention discloses a Beidou satellite navigator with multiple microstrip antennas. The Beidou satellite navigator comprises a shell, a supporting plate, a supporting frame and the three microstrip antennas. One side of the supporting plate is connected with one end of the shell through a hinge in a rotating mode, one end of the supporting frame is connected with the rear side surface of the shell in a rotating mode, a supporting groove fixing the supporting frame is formed in the upper side surface of the supporting plate, and the three microstrip antennas are arranged on the rear side surface in the shell, the upper side surface in the supporting plate and the lower side surface in the supporting plate respectively. By arranging the multiple microstrip slot antennas, the navigator has 120% of impedance bandwidth and the good radiation characteristic within the frequency coverage area, is small in size and can carry out navigation accurately in the environment that satellite signals are weak.

Description

technical field [0001] The invention relates to a navigator, in particular to a Beidou satellite navigator adopting multi-microstrip antennas. Background technique [0002] Navigator is a product of modern technology, generally used for car and ship navigation. It is a kind of smart map, and can update the map data in it. At the same time, it can be used as a guide to prompt the driving route during use. Now some navigation The instrument uses the global satellite positioning and communication system independently developed by my country - the Beidou satellite navigation system. The working principle of its global positioning is to form a communication between the navigator and the navigation satellite, but buildings and metals will have certain influence on the navigation signal. At the same time, because of the small size of the navigator, its antenna is small, and its ability to receive navigation signals is limited, so in some environments, star loss or drift may occur. ...
