Abstract
A stacked multi-band antenna for a satellite positioning system comprises a stack of conductive patches, which are each dimensioned 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 conductive patches. Each pair of conductive strips is adapted for radiatively coupling to an associate conductive patch of the stack of conductive patches. An RF front end 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.
