Systems and methods for expanding the axial ratio bandwidth at very low elevations are provided. In certain implementations, a system comprises an antenna having a first group of antenna elements and a second group of antenna elements, wherein elements in the first group of antenna elements are reflectively symmetrical about a plane with corresponding elements in the second group of antenna elements; and a global navigation satellite system receiver configured to drive the antenna and process received signals from global navigation satellite system satellites, wherein the global navigation satellite system receiver operates elements in the first group of antenna elements with a first phase delay and the second group of antenna elements with a second, different phase delay and drives the first group of antenna elements and the second group of antenna elements at different power levels. |
