First Claim
Patent Images
1. An antenna comprising:
- a parallel plate waveguide having a top plate, a bottom plate, and a transmission port transmitting a planar electromagnetic wave; and
,at least one radiating element extending from the top plate of the waveguide over a coupling aperture formed in the top plate, the element comprising a sidewall forming a distal opening spaced apart from the top plate of the waveguide, and the coupling aperture is located such that it couples part of the wave energy of the planar electromagnetic wave from the waveguide and into the radiating element and the remaining part of the planar electromagnetic wave continues to propagate inside the parallel plate waveguide beyond the element.

Abstract
An antenna is provided. The antenna may include at least one open-ended structure extending from a surface of a waveguide. The open-ended structure may have a cross section of many different shapes. The walls of the structure may be movable. The antenna structure may be rotated. The antenna may incorporate a number of different wave feeds. The antenna may provide two-dimensional beam steering.
