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

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