Abstract:
A hardware front-end for a software-defined GNSS receiver, which includes an antenna connected to a transmission line that is connected to a pair of separate circuits, one for receiving L1 signals and one for receiving L2 signals. Each circuit includes at least one bandpass filter, at least one LNA, and a single-chip GNSS receiver that receives analog RF signals and provides digitized I and Q signals. The pair of circuits differ in that a first one is designed to receive, filter, and amplify RF signals at the L1 frequency corresponding to the designed input frequency of the receiver and the second one is designed to receive, filter, and amplify RF signals at the L2 frequency, which is significantly different from the first frequency. The second circuit also includes a mixer to convert the L2 frequency to the L1 frequency, so that a similar receiver can be used in each circuit.

Claim (Index 20):
A GNSS antenna assembly, comprising:\n a multilayer antenna board containing an L1 patch antenna of a first width, an L2 patch antenna of a second width that is greater than the first width, a ground plane of a third width that is equal to or greater than the second width, and one or more electrical contact pads on a first surface of the antenna board, the contact pads being in conductive contact with the ground plane of the antenna board; a ground plane board containing a ground plane of a fourth width that is greater than the third width and one or more electrical contact pads on a first surface of the ground plane board, the contact pads being in conductive contact with the ground plane of the ground plane board; wherein the contact pads of the antenna board and the contact pads of the ground plane board are in conductive contact with each other.
