Abstract: A transparent antenna system is disclosed that reduces or removes optical artifacts when used in connection with devices through which a user can view content. For example, the transparent antenna system utilizes a transparent conductive mesh (e.g., metal mesh) that includes randomized patterns of apertures. Thus, when such meshes are overlaid on an LED display (e.g., as with a pair of AR glasses), the randomized patterns of apertures reduce or eliminate the occurrence of optical artifacts. Moreover, the transparent antenna system can maintain a minimum average pitch over the transparent conductive mesh such that performance levels of the transparent antenna system is also maintained. Various other methods, systems, and computer-readable media are also disclosed.
