Abstract
An antenna assembly (10) includes a substrate (24) and an array of antenna elements (26). Each antenna element is supported by the substrate at respective locations so that the antenna elements are arranged in space in a helix pattern (28). The helix pattern has a pitch along an axis about which the helix pattern turns. An arc length spacing of the antenna elements along the helix pattern and the pitch are arranged so that, in a transmit mode, a radio frequency (RF) signal fed to each of the antenna elements results in emission of a radiated signal with a rotational wave front from the antenna assembly at a first frequency and a first mode.
