    Abstract: A waveguide architecture for a dual-polarized antenna including multiple antenna elements. Aspects are directed to dual-polarized antenna architectures where each antenna element includes a polarizer having an individual waveguide with dual-polarization signal propagation and divided waveguides associated with each basis polarization. The waveguide architecture may include unit cells having corporate waveguide networks associated with each basis polarization connecting each divided waveguide of the polarizers of each antenna element in the unit cell with a respective common waveguide. The waveguide networks may have waveguide elements located within the unit-cell boundary with a small or minimized inter-element distance. Thus, unit cells may be positioned adjacent to each other in a waveguide device assembly for a dual-polarized antenna array without increased inter-element distance between antenna elements of adjacent unit cells. Antenna waveguide ports may be connected to unit cell common waveguides using elevation and azimuth waveguide networks of the corporate type.

    Abstract: Disclosed is a shaped horn in conjunction with a dielectric tube for enhanced aperture directivity that can achieve a near optimum efficiency. The shaped horn provides additional mode control to provide an improved off-axis cross-polarization response. The horn shape can be individually optimized for isolated horns or for horns in a feed array. The feed array environment can produce results that lead to a different optimized shape than the isolated horn. Lower off axis cross-polarization can result in improved efficiency and susceptibility to interference.

    Abstract: In an example embodiment, an in-phase H-plane T-junction can comprise: a first waveguide port; a second waveguide port; a third waveguide port, wherein the third waveguide port can be a common port; and an E-plane septum. The first, second, and third waveguide ports can be in the H-plane and can be each connected to each other in a T configuration. The T-junction can be configured such that microwave signals in a first band can be in-phase with each other at the first and second waveguide ports, and microwave signals in a second band can be in-phase with each other at the first and second waveguide ports. The H-plane T-junction can be at least one of a power combiner and a power divider.

The waveguide combining portion can be configured to combine two signals that are each respectively received from the second waveguide dividing portion and third waveguide dividing portion. In general an in-phase recombinant waveguide combiner/divider can comprise more junctions than output ports of a conservative power divider network structure. In an example embodiment, for a N-way waveguide power divider, there can be at least N+1 waveguide junctions.
