Abstract
An exemplary aperiodic antenna array comprises a plurality of first elements radiating electromagnetic energy over a first bandwidth including a first frequency. Each of the first elements is spaced apart from a pattern center by an element distance and from the nearest first element by an element spacing in a regulated pattern. In the regulated pattern, the element spacing increases as the element distance increases. The plurality of first elements are configured to generate a first radiation pattern. The antenna array also comprises a second element positioned within a group of first elements from the plurality of first elements. Each element distance between the first elements in the group of first elements is greater than one-half of a first wavelength corresponding to the first frequency. The second element is configured to generate a second radiation pattern. The second radiation pattern combines with the first radiation pattern to form a composite radiation pattern.
