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.
