Expanding lattice notch array antenna

摘要

The present disclosure is directed toward a notch array antenna comprised of a plurality of notch antenna elements projecting from a surface of a base plate at varying angles to provide an array having an expanding element structure. The plurality of notch antenna elements are organized in a regular spacing in one or two directions along the surface of the base plate and each of the plurality of notch antenna elements is formed by a gap between conductive parts projecting from the first surface of the base plate. The notch array antenna includes a plurality of notch antenna element axes, whereby each notch antenna element axis is defined along a centerline of one of the notch antenna elements. Each notch antenna element axis may extend from the first surface of the base plate at systematically varying angles with respect to an axis perpendicular to the base plate.

1. An expanding lattice notch antenna comprising:
a base plate having first and second opposing surfaces; a plurality of notch antenna elements organized in a regular spacing in one or two directions along the first surface of the base plate, wherein each of the plurality of notch antenna elements is formed by a gap between conductive parts projecting from the first surface of the base plate; a plurality of notch antenna element axes, wherein each notch antenna element axis is defined along a centerline of one of the plurality of notch antenna elements, each notch antenna element axis extending from the first surface of the base plate at systematically varying angles with respect to an axis perpendicular to the base plate, and each notch antenna element axis in each of the plurality of notch antenna elements having systematically varying lengths, such that a plurality of first endpoints of each notch antenna element axis lie on a plane equidistant in a perpendicular direction to the first surface of the base plate, forming a notch array antenna.
