Abstract
The present invention provides a high-performance and lightweight 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 RF performance of the array is enhanced by using ribs and sleeves to reduce the dielectric volume of the support structures of the antenna elements, and by providing apertures within the sleeves of the support structures and between the ribs thereof.
