摘要： A wide band antenna tracking modulator and method is disclosed. The system includes a common port for receiving an electromagnetic signal, a waveguide connected to the common port, at least a pair of side arms and a pair of coupling slots separated along an axis of the waveguide coupling the electromagnetic signals between the waveguide and the pair of side arms. The pair of coupling slots substantially coupled a higher order TE mode signal while substantially not coupling a primary TE mode signal. The method includes substantially coupling a higher order Transverse Electric (TE) mode signal of the electromagnetic signal while substantially not coupling a primary TE mode signal of the electromagnetic signal to at least a pair of side arms coupled to the wave guide though a pair of coupling slots separated along the axis of the waveguide.

摘要： An ortho mode transducer (OMT)/multiplexer assembly having a corrugated junction and a coaxial dual mode waveguide resonator disposed around a central cylindrical waveguide. The corrugated junction diplexes signals, the higher frequencies passing through the central cylindrical waveguide and the lower frequencies passing through the coaxial dual mode resonator. Apertures in the dual mode resonator couple to an exit port and extract a first polarization from the lower frequencies passing through the dual mode resonator. The assembly may include a second aperture in the dual mode resonator for extracting a second polarization in a manner similar to the operation of the first aperture.

摘要： A beam waveguide may include a first set of dual offset reflectors and a second set of dual offset reflectors. The first set of dual offset reflectors and the second set of dual offset reflectors may each include reflector geometries to produce a radiation pattern that is symmetric about a first axis between the first and second set of dual offset reflectors and to produce an axi-symmetric beam from the second set of dual offset reflectors that is unaffected by any rotation of the first and second set of dual offset reflectors relative to one another about the first axis.
