PATCH ANTENNA ARRAY FOR TRANSMISSION OF HERMITE-GAUSSIAN AND LAGUERRE GAUSSIAN BEAMS

摘要

A multi-level antenna array includes a plurality of patch antennas. A plurality of layers are separated from each other by a distance. Each of the plurality of layers further supports a portion of the plurality of patch antennas. A plurality of connectors is each associated with one of the plurality of layers to supply a signal for transmission by the associated layer. A feed network on each of the plurality of layers provides a connection between a connector of the plurality of connectors associated with the layer and the portion of the plurality of patch antennas located on the layer. A length of the connection between the connector and each of the portion of the plurality of patch antennas applies a different phase to each of the portion of the plurality of patch antennas on the layer.
