Abstract
A frequency beam-steered leaky wave antenna suitable for integration in a substrate such as a printed circuit board includes a waveguide formed from a first electrically-conductive surface and a second electrically conductive surfaces forming upper and lower surfaces of the waveguide and electrically-conductive vias form first and second sidewalls disposed between the upper and lower surfaces along a length of the waveguide. The waveguide has slotted openings distributed along the upper surface and a width of the waveguide is defined by a distance between the two sidewalls that varies along the length of the waveguide. A portion of radiofrequency energy travelling along a length of the waveguide is radiated away from the waveguide through the slotted openings. Performance characteristics of the antenna such as its directivity and operational bandwidth can be tuned by adjusting the geometry of the slotted openings and positioning of the vias.
