1. An antenna configured to produce a variable phase response, the antenna comprising:
a single antenna structure configured to receive electromagnetic radiation and comprising an antenna geometry,
wherein the antenna geometry is configured to cause a variable phase shift in the electromagnetic radiation based on an angular position of a direction of propagation of the electromagnetic radiation relative to azimuth.
