FIELD: radio engineering.
SUBSTANCE: stacked multi-band antenna for a satellite positioning system comprises a stack of conducting radiators, dimensions of each of which are so as to be respectively operative in a dedicated frequency band. An excitation line section comprising pairs of conductive strips is arranged underneath the stack of conducting radiators. Each pair of conductive strips is adapted for radiatively coupling to an associate conducting radiator of the stack of conducting radiators. A high frequency channel with at least one electric circuit is arranged in a triplate section underneath the excitation line section for operatively connecting the pairs of conductive strips to a satellite positioning receiver. The at least one electric circuit includes filters and amplifiers for respectively filtering and amplifying signals from the pairs of conductive strips, during antenna operation.
EFFECT: high accuracy of finding the position of an object.
