The invention belongs to the technical field of communication and navigation and in particular relates to a multi-frequency navigation terminal antenna. A top-layer feeding point is arranged at the center of a first-layer micro-strip patch; a central feeding hole is vertically formed in the top-layer feeding point; a first feeding point is arranged at a second-layer micro-strip patch; a first feeding hole is vertically formed in the first feeding point; a second feeding point is arranged at a third-layer micro-strip patch; a second feeding hole is vertically formed in the second feeding point; a third feeding point is arranged at a fourth-layer micro-strip patch. The antenna also comprises first short circuit metallized via holes and second short circuit metallized via holes which are used for eliminating coupling influence of feeding probes in all the feeding holes. The multi-frequency navigation terminal antenna disclosed by the invention can cover L band and S band of first-generation Beidou, B1 band and B3 band of second-generation Beidou and L1 band of a GPS (Global Positioning System); the demands on minimization and lightness of antenna size are met while good impedance bandwidth, axial ratio bandwidth and high-gain performance can be guaranteed.
