Abstract:
A communication device includes at least one radio that comprises signal processing circuitry, and at least one antenna coupled to the signal processing circuitry to send and receive radio signals. A component of the communication device requires user visibility and includes an isolator for isolating the at least one antenna, the isolator comprising at least one film that includes a transparent conductor. The component that requires user visibility may be a display screen or part of the chassis of a transparent communication device. The transparent conductor comprises a transparent conducting oxide such as indium tin oxide, indium tin oxide ink, graphite material, carbon nanotubes, or a conductive polymer.
Abstract:
Some demonstrative embodiments include devices, systems and/or methods of wireless communication via a dual directional antenna. For example, a device may include a hinge to connect between first and second elements to allow rotating the first element between first and second rotational states with respect to the second element, and a rotatable dual directional wireless communication antenna coupled to the hinge. The dual directional wireless communication antenna may be configured to communicate wireless communication signals in a first direction, when the first element is at the first rotational state, and to communicate the wireless communication signals in a second direction, different from the first direction, when the first element is at the second rotational state.
Abstract:
Embodiments of millimeter-wave antenna structures are generally described herein. The antenna structure may include an a radiating-element layer comprising a patterned conductive material, a ground layer comprising conductive material disposed on a dielectric substrate, and a feed-line layer comprising conductive material disposed on a dielectric substrate. In some embodiments, the antenna structure may include an air-gap layer disposed between the radiating-element layer and the ground layer. The air-gap layer may include spacing elements to separate the radiating-element layer and the ground layer by a predetermined distance. In some other embodiments, the radiating-element layer may be disposed on a radiating-element dielectric substrate which may include one or more cavities between the radiating-element layer and the ground layer.
