Abstract: Exemplary embodiments are provided of antennas and antenna systems including the same. In an exemplary embodiment, an antenna generally includes a radiating patch element having an annular rectangular shape. An antenna ground plane is spaced apart from the radiating patch element. A feeding element electrically coupled to the radiating patch element via proximity coupling. The antenna also includes at least two shorting elements electrically coupling the radiating patch element to the antenna ground plane. In other exemplary embodiments, the antenna systems include at least one active GPS antenna, at least one passive antenna, and an isolator.

Abstract: According to various aspects, exemplary embodiments are disclosed of ground independent multi-band antenna assemblies. In an exemplary embodiment, a ground independent multi-band antenna assembly is operable within at least a first frequency range and a second frequency range different than the first frequency range. The antenna assembly generally includes an annular ground element, a feed element, a patch element, and a high band element. The feed element includes a feeding point and a shorting point electrically connected to the annular ground element. The patch element is electrically shorted to the annular ground element by the feed element. The high band element is electrically connected to the feed element.
