Abstract
An antenna array may be constructed using a plurality of tubes of electrically conducted material in conjunction with an additionally electrically conductive component which covers the front faces of tubes and at least part of the sides. Between the structures, a further electrically conductive material may be placed separated by dielectric material, and may be used to provide radiating elements and a feed structure by producing stripline structures. This structure is thereby able to reduce cavity back slots fed with triplate stripline along the sides of the tubes. This structure, particularly when made from plastics material, is low in complexity and cost and lightweight. These features overcome many of the disadvantages of the existing designs.
