1. A phase array antenna system, comprising:
a first panel comprising a first array of antennas in a first grid pattern for transmitting first signals, wherein the first panel comprises a first edge having a first vertex at an end and a second vertex at an opposing end; and
a second panel comprising a second array of antennas in a second grid pattern for receiving second signals, wherein the second panel comprises a second edge having a third vertex at an end and a fourth vertex at an opposing end, and the third vertex being located closer to the first vertex as compared to the second vertex;
wherein the first panel and the second panel are fixedly disposed in a plane and co-located along a direction in the plane;
wherein the first grid pattern is the same as the second grid pattern; and
wherein the first panel and the second panel are rotated by an angle such that (i) the first edge of the first panel is adjacent to and nonparallel with the second edge of the second panel and (ii) a distance between the first vertex of the first panel and the third vertex of the second panel is different than a distance between the second vertex of the first panel and the fourth vertex of the second panel.
