Abstract:
1. An antenna for receiving satellite signals, comprising: a ground plane; a first antenna element and a second antenna element, wherein the first antenna element and the second antenna element are electrically separate from one another; a first impedance matching circuit coupled to the first antenna element, wherein the first impedance matching circuit includes a first plurality of filters; and a second impedance matching circuit coupled to the second antenna element, wherein the second impedance matching circuit includes a second plurality of filters, wherein the first and second antenna elements each include: a first segment substantially perpendicular to the ground plane; a second segment coupled to the first segment, extending away from a central vertical axis of the antenna, and substantially parallel to the ground plane; a third segment coupled to the second segment and substantially perpendicular to the ground plane; and a fourth segment coupled to the third segment and substantially parallel to the ground plane, the fourth segment extending from the third segment toward the central vertical axis of the antenna; wherein the first and second antenna elements are configured for receiving radiation that is circularly polarized.
