Abstract
Antenna systems for receiving right and left hand circularly polarized signals are disclosed. An antenna system embodiment includes a top printed circuit board (PCB), a ground plane, and an antenna array including four conductive antenna elements positioned at relative zero, 90, 180, and 270 degree increments radially about a shared center point on the PCB, with each antenna element sloping upward in a left-handed direction from the ground plane towards the top PCB and connected to the ground plane and top PCB.
