Patent ID: 8289213

Claim:
A stacked multi-band antenna for a satellite positioning system comprising: a stack of conductive patches, each respective conductive patch being dimensioned so as to be operative in a dedicated frequency band; an excitation line section arranged underneath said stack of conductive patches, said excitation line section comprising pairs of conductive strips, each pair of conductive strips for radiatively coupling to an associate conductive patch of said stack of conductive patches; and at least one electric circuit for operatively connecting said pairs of conductive strips to a satellite positioning receiver, said at least one electric circuit being arranged in a triplate section arranged underneath said excitation line section, said triplate section comprising a first dielectric disk and a second dielectric disk plated with a conductive layer, said at least one electric circuit being sandwiched between the first dielectric disk plated with a conducting layer on a side facing away from the at least one electric circuit and the second dielectric disk plated with a conductive layer on a side facing away from the at least one electric circuit, said at least one electric circuit including filters and amplifiers for respectively filtering and amplifying signals from said pairs of conductive strips.
