Abstract
The radio-over-fiber (RoF) transponder includes a converter unit adapted to convert RF electrical signals into optical signals and vice versa, and an antenna system electrically coupled to the converter unit. The antenna system includes first and second Z-shaped patch antenna elements formed on an antenna substrate. These patches are adapted to respectively transmit and receive radio-frequency (RF) electromagnetic radiation at a first frequency f(e.g., 2.4 GHz) over a first picocell. The antenna system also includes a square patch antenna element formed atop the antenna substrate surface between the first and second Z-shaped patch antenna elements. The square patch antenna is adapted to transmit and receive RF electromagnetic radiation at a second frequency f(e.g., 5.2 GHz) over a second picocell substantially co-located with the first picocell. One or more spaced-apart transponders can be supported by one or more optical fibers to form an array of picocells.
