A through-glass antenna system ( 10 ) includes a patch antenna ( 14 ) mounted on a horizontal flat surface ( 51 ) of a three-dimensional conductive structure ( 16 ). The structure can serve as a ground plane for the patch antenna and further include bent and folded sides ( 52, 54 , and 56 ) where one side includes a conductive surface ( 52 ) that extends below the horizontal flat surface and if necessary further bends at an approximate angle of a vehicle's front or rear window ( 30 ), a substantially planar external coupler ( 26 ) having an inside portion ( 63 ) and an edge portion ( 67 ) where the patch antenna is connected to the inside portion ( 63 ) of the external coupler, a substantially planar internal coupler ( 32 ) having an inside portion ( 7 ) 3 and an edge portion ( 77 ), and a low noise amplifier ( 36 ) where the low noise amplifier is connected to the edge portion of the internal coupler.
