摘要： A tuneable impedance surface for steering and/or focusing a radio frequency beam. The tunable surface comprises a ground plane; a plurality of elements disposed a distance from the ground plane, the distance being less than a wavelength of the radio frequency beam; and a capacitor arrangement for controllably varying the capacitance of at least selected ones of adjacent elements. A method of tuning the high impedance surface allows the surface to mimic, for example, a parabolic reflector or a diffraction grating.

摘要： A method and apparatus for creating uniform heating of an microwave absorptive target. A microwave housing has a longitudinal axis and propagates a waveguide mode at an operating frequency. The target is located in an axial cross-sectional area relative to the longitudinal axis. First layer conductive strips are layered proximal to an inner wall of the microwave housing, substantially parallel to the longitudinal axis and being separated from an adjacent first layer conductive strip by a respective first layer gap, the inner wall acting as a ground plane. Second layer conductive strips are layered proximal to the first layer of conductive strips, parallel to the longitudinal axis and being separated from an adjacent second layer conductive strip by a respective second layer gap. Each first layer gap is centered under a respective second layer conductive strip and each second layer gap is centered over a conductive layer.

摘要： A low-profile dual-band antenna includes a ground plane. An “E”-shaped metal plate is located a first distance from the ground plane and includes first and second outer extensions and an inner extension of the metal plate. A feed tab connects the inner extension and the ground plane. A shorting tab connects the inner extension and the ground plane. The low-profile dual-band antenna communicates first radio frequency (RF) signals in a first RF band and second RF signals in a second RF band. The first RF signals and the second RF signals are vertical polarized signals. The low-profile dual-band antenna produces a radiation pattern that is omnidirectional in the azimuth plane and vertically polarized in a horizontal plane when communicating the first RF signals and the second RF signals. The first RF band and the second RF band can be independently tuned.
