Beam shaping for reconfigurable holographic antennas
First Claim
1. A method of shaping an antenna beam pattern of an antenna, the method comprising:
- driving a first holographic pattern onto a layer of the antenna while a feed wave excites the layer;
receiving an antenna pattern metric representative of a first antenna pattern generated by the antenna while the first holographic pattern is driven onto the layer;
generating a modified holographic pattern in response to the antenna pattern metric; and
driving the modified holographic pattern onto the layer of the antenna.

Abstract
A reconfigurable holographic antenna and a method of shaping an antenna beam pattern of a reconfigurable holographic antenna is disclosed. A baseline holographic pattern is driven onto a reconfigurable layer of the reconfigurable holographic antenna while a feed wave excites the reconfigurable layer. An antenna pattern metric representative of a baseline antenna pattern is received. The baseline antenna pattern is generated by the reconfigurable holographic antenna while the baseline holographic pattern is driven onto the reconfigurable layer. A modified holographic pattern is generated in response to the antenna pattern metric. The modified holographic pattern is driven onto the reconfigurable layer of the reconfigurable holographic antenna to generate an improved antenna pattern.
