Abstract
The present invention provides a high-performance helical antenna element and array thereof for use in an aircraft communication system or the like, where stringent spatial restrictions and gain requirements generally apply. The performance of the array is enhanced by connecting conductive plates to the windings of the antenna elements at the terminal ends thereof such that the conductive plates are offset from the axes of the antenna elements and toward the center of the array.
