Abstract: First and second electrically conductive rods are provided inside a shielded electromagnetic test chamber. These rods are energized to radiate electromagnetic energy inside the chamber. The rods are mounted inside the chamber at right angles to one another, the first rod is movable through the interior volume in a first direction perpendicular to its long axis, and the second rod is movable through the chamber in a second direction perpendicular both to its own long axis and to the first rod's direction of motion. Energy is supplied to the two rods in a way that enhances the uniformity of the electromagnetic field applied to a working volume inside the chamber as the two rods move through the chamber.

Abstract: An antenna employs cylindrical Fresnel zone plate (CFZP) construction in combination with a reflective ground plate and a sectorial reflector to enhance antenna gain, while lowering assembly cost and improving antenna placement flexibility. By forming a surface of symmetry for the antenna, the ground plate allows the antenna to mimic the operation of a symmetrical CFZP antenna using only half the nominal number of Fresnel elements. Further, the sectorial reflector restricts radiated emissions over a desired sector angle, minimizing radiation in undesirable directions, such as toward mounting walls or other nearby surfaces that would cause unwanted signal reflections, such as might aggravate multipath signal phenomenon.
