WAVEGUIDES FOR DIGITAL COMMUNICATION DEVICES

摘要

Various of the disclosed embodiments use ITO and ITO-like materials or structures to serve as a waveguide for device communications, e.g., for mobile phone communication. Various embodiments employ an economical design, wherein one or more wireless antennas are integrated into or in conjunction with the display of a communications device as a waveguide antenna. The waveguide may use space more economically than traditional designs. In some embodiments, the waveguide can provide a wider range of viable operational frequencies. Additionally, in some embodiments, a square surface area of the waveguide optimizes the area to length ratio, which may reduce the resistance when the structure includes a lossy material. The waveguide antenna may be composed of ITO or ITO-like materials, which facilitate waveguide propagation while retaining a visually transparent character.
