1. An antenna system, comprising:
a ground plane at a first layer of a printed circuit board (PCB), wherein a first edge of the ground plane is perpendicular to and longer than a second edge of the ground plane;
a phased array comprising an array of radiator stacks overlapping the ground plane, wherein a first radiator stack in the array comprises a first radiator at a second layer of the PCB, the first radiator having a first edge that is parallel with the first edge of the ground plane and a second edge that is parallel with the second edge of the ground plane, and wherein the first radiator stack further comprises a second radiator at a third layer of the PCB, the second radiator having a first edge that is nonparallel with the first edge of the ground plane and with the second edge of the ground plane;
a first feed and a second feed coupled to the first radiator, the first feed configured for signals having a first polarization, the second feed configured for signals having a second polarization; and
a third feed and a fourth feed coupled to the second radiator, the third feed configured for signals having the first polarization, the fourth feed configured for signals having the second polarization,
wherein the array of radiator stacks comprises a second radiator stack, a third radiator stack and a fourth radiator stack, each comprising a radiator having a first edge that is parallel with the first edge of the ground plane and a second edge that is parallel with the second edge of the ground plane, and each comprising another radiator having a first edge that is nonparallel with the first edge of the ground plane and with the second edge of the ground plane.
