Abstract
An antenna assembly a spiral antenna feed and a programmable circuit. The spiral antenna feed includes a substrate, a spiral antenna element, and a feed point. The substrate has a three-dimensional hyperbolic shaped region, which supports the spiral antenna element such that the spiral antenna element has an overall shape approximating a three-dimensional hyperbolic shape. The feed point is coupled to a connection point of the spiral antenna element. The programmable circuit produces a projected artificial magnetic conductor reflector dish that reflects an inbound RF signal to the spiral antenna feed and reflects an outbound RF signal from the spiral antenna feed.
