1. An antenna array, comprising:
a first ground plane;
a second ground plane disposed below the first ground plane;
a first folded monopole antenna disposed between the first ground plane and the second ground plane, the first folded monopole antenna comprising a first driven arm, a first parasitic arm, and a first short connecting the first driven arm to the first parasitic arm;
an antenna disposed above the first ground plane; and
a first feedline in electrical communication with the antenna such that an electrical signal input to the first feedline drives the antenna, wherein the first feedline extends through a cavity formed within the first parasitic arm of the first folded monopole antenna;
a third ground plane disposed below the second ground plane;
a second folded monopole antenna disposed between the second ground plane and the third ground plane, the second folded monopole antenna comprising a second driven arm, a second parasitic arm, a second short connecting the second driven arm to the second parasitic arm, and a second cavity formed within the second parasitic arm; and
a second feedline is in electrical communication with the first folded monopole antenna such that a second electrical signal input to the second feedline drives the first folded monopole antenna, wherein the second feedline and the first feedline extend through the second cavity formed within the second parasitic arm.
