Abstract
An electronically steerable helical or spiral antenna includes a monopole antenna element disposed within at least one helical or spiral antenna element. The antenna can be electronically steered, i.e., its radiation pattern can be altered, such that the antenna radiates in a desired direction, without mechanically changing a direction in which the antenna is aimed and without mechanically changing orientation of any of the antenna's elements, by adjusting amplitude and phase of a signal fed to the monopole antenna element, relative to a signal fed to the at least one helical or spiral antenna element.
