Multimode Circular Antenna Array for Spatially Encoded Data Transmission

We present a new technique for data transmission by wireless. We show how a circular array can have each of its major radiating modes orthogonally encoded with data. These data-impressed radiating modes are concurrently excited, and then spatially combined, in order to give a structured far-field ra...

Zusammenfassung:We present a new technique for data transmission by wireless. We show how a circular array can have each of its major radiating modes orthogonally encoded with data. These data-impressed radiating modes are concurrently excited, and then spatially combined, in order to give a structured far-field radiation pattern. Also discussed is how a receiver can recover these orthogonal data streams. A proof of principle multimode circular array (MMCA) is designed, simulated, and tested at 900 MHz.
