Abstract

The invention provides a combined navigation positioning antenna. The combined navigation positioning antenna comprises a substrate part, a patch antenna assembly and a spiral antenna assembly, wherein the substrate part is of a flat plate shape, the patch antenna assembly comprises at least one patch antenna, the at least one patch antenna is arranged on one side surface of the substrate part, the spiral antenna assembly comprises at least one spiral antenna, and the at least one spiral antenna is arranged on one side of the substrate part and is spatially separated from the patch antenna assembly. The combined antenna is combined and formed through the patch antenna and the spiral antenna, the problem of size miniature of a multi-band antenna is solved, and the problems of relatively poor isolation degree among the multi-band antennas and relatively poor gain and bandwidth of the multi-band antenna for specific frequency band are solved.

Description

technical field [0001] The invention belongs to the technical field of antennas, and relates to a navigation and positioning antenna, in particular to a combined navigation and positioning antenna, in particular to a combined antenna formed by combining a patch antenna and a helical antenna. Background technique [0002] With the development of the satellite navigation system, especially with the development and improvement of my country's Beidou satellite navigation system, the navigation and positioning and mobile communication based on the Beidou satellite have gained more and more applications in the military and civilian fields, such as transportation monitoring , hydrological monitoring, flood control and flood control, and providing comprehensive services such as positioning, communication and timing, thus playing an increasingly important role in people's work and life. [0003] In satellite navigation technology and satellite communication technology, antennas in ter...
