Abstract:
A display, such as for a touch-sensitive communication device, can include a transparent cover glass, pixels that emit light through the cover glass, and multiple antennas positioned along respective paths in an inactive area between the pixels. The antennas do not obstruct the light produced by the pixels, and can therefore be composed of opaque materials, such as metallic thin films, without affecting the optical properties of the display. In some examples, several antennas can have the same size and shape but different orientations, so that a radio can switch between or among the antennas to optimize reception. In some examples, the antennas can have different sizes and/or shapes, so that the antennas can send and/or receive radio signals in different frequency ranges of the electromagnetic spectrum. In some examples, locating the antennas in the display can allow the device to include a metallic housing.
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.
