    摘要: When illuminated with a plane wave a variable cross-coupling partial reflector reflects a specific amount of a cross-polarized field and a specific amount of a co-polarized field and transmits the remaining power with low attenuation. This is achieved with a pair of frequency selective surfaces (FSS) that are rotated with respect to the incident plane wave. The FSSs can be fixed with a given alignment for a particular application or a tuning mechanism can be provided to independently rotate the surfaces and adapt the reflected co- and cross-polarized fields to changing requirements. Of particular interest is the ability to provide a specific amount of cross-polarized reflected power while reflecting no co-polarized field over a certain range of wavelengths. This will be useful to increase power efficiency in, for example, wave power sources that utilize quasi-optical power by causing oscillations in reflection amplifier arrays.

    摘要: Steering of an electromagnetic beam of energy in the upper plate of a plate waveguide of a traveling wave antenna concurrently with the formation of a flat phase front and collimation of the electromagnetic beam is achieved by providing a second waveguide beneath the lower plate of the first waveguide and providing a 180% bend parabolic main reflector to reflect the energy beam to the upper plate of the upper waveguide. A feed horn is located in the lower waveguide and illuminates a pivotal subreflector which reflects the energy to the parabolic main reflector. By rotating the subreflector about its pivot point, the beam which is radiated to the upper waveguide is angularly shifted or steered.

    摘要: A microstrip transmission line to waveguide transmission line transition. A microstrip transmission line is separated from a ground plane by a dielectric therebetween. The microstrip transmission line terminates at a microstrip transmission line open circuit end. A waveguide channel having narrow dimension waveguide walls and a broad dimension base waveguide wall connected therebetween is provided. The waveguide channel has a waveguide short circuit wall located along the channel. The narrow dimension waveguide walls are coupled with the ground plane to provide a broad dimension top waveguide wall for the waveguide transmission line. An aperture is located transverse to the microstrip transmission line and passes through an aperture ground plane opening in the ground plane. The aperture is located proximate to the microstrip transmission line open circuit end to provide a microstrip transmission line open circuit stub and proximate to the waveguide short circuit wall to provide a waveguide transmission line short circuit stub.
