Patch antenna array for transmission of Hermite-Gaussian and Laguerre Gaussian beams
First Claim
1. A multi-level antenna array, comprising:
- a plurality of patch antennas;
a plurality of layers, each of the plurality of layers separated from each other by a distance, each of the plurality of layers further supporting a portion of the plurality of patch antennas;
a plurality of connectors, each of the plurality of connectors associated with one of the plurality of layers, for supplying a signal for transmission by the associated layer;
a feed network on each of the plurality of layers for providing 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;
wherein each layer of the plurality of layers transmits the signal having a different orthogonal function applied thereto that multiplexes each of the signals having the different orthogonal function applied thereto onto a single transmission beam; and
a parabolic reflector for reflecting the single transmission beam from the plurality of layers of the multi-level antenna array.

Abstract
An antenna array includes a plurality of patch antennas including a plurality of layers. Each of the plurality of layers are separated by a distance and each support a portion of the plurality of patch antennas. A plurality of connectors are each associated with one of the plurality of layers and 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 associated with the layer and the portion of the patch antennas located on the layer. Each layer transmits a signal having a different orthogonal function applied thereto that multiplexes each of the signals having a different orthogonal function applied thereto onto a single transmission beam. A parabolic reflector reflects the single transmission beam from the plurality of layers of the antenna array.
