Abstract
Various antenna assemblies are disclosed. In one example, an antenna assembly includes a reflector including a first ground plane, a second ground plane below and spaced apart from the reflector, an antenna adjacent a surface of the reflector opposite the second ground plane, and a grounding post galvanically connecting the first ground plane and the second ground plane.
Claims22
An antenna assembly comprising:
- a reflector including a first ground plane;
- a second ground plane below and spaced apart from the reflector;
- an antenna adjacent a surface of the reflector opposite the second ground plane;
- a strip transmission line positioned between the first ground plane and the second ground plane for coupling with the antenna;
- and
- a grounding post galvanically connecting the first ground plane and the second ground plane, the grounding post configured to maintain a spatial separation of the first ground plane and the second ground plane.

A crossed dipole antenna assembly comprising:
- a first antenna member;
- a second antenna member;
- a third antenna member;
- a fourth antenna member;
- a first ground plane;
- a non-conductive carrier disposed above the first ground plane;
- wherein:
