Claim 0:
1. A mechanically reconfigurable antenna radiator system comprising: an antenna and a moiré radiation pattern actuated by a low power actuation mechanism; wherein the moiré radiation pattern includes an intersection of repeated patterns altering the antenna's characteristics including tuning the operating frequency, changing the antenna moiré radiation pattern, and altering the antenna's polarization between an elliptical or circular polarization; wherein the low power actuation mechanism comprises a small mechanical motion to create a geometric variation in the moiré radiation pattern to significantly change the antenna's characteristics; the small mechanical motion comprises a fixed rotation to change the polarization of the antenna or reconfigure the radiation pattern; the rotational change allows for continuous steering of the radiation pattern of the antenna with fine tuning over a 360° range; and the low power actuation mechanism is a ratchet mechanism driven by a shape memory alloy actuator.
