In an example embodiment, a waveguide device comprises: a first common waveguide; a polarizer section, the polarizer section including a conductive septum dividing the first common waveguide into a first divided waveguide portion and a second waveguide divided portion; a second waveguide coupled to the first divided waveguide portion of the polarizer section; a third waveguide coupled to the second divided waveguide portion of the polarizer section; and a dielectric insert. The dielectric insert includes a first dielectric portion partially filling the polarizer section. The conductive septum and the dielectric portion convert a signal between a polarized state in the first common waveguide and a first polarization component in the second waveguide and a second polarization component in the third waveguide.

A system, device, and method for a broad-band array antenna are presented. More particularly, the application relates to a broad-band fragmented aperture phased array antenna for the Ka, K, and/or Ku frequency bands. In various exemplary embodiments, the antenna system may support dynamic polarization degradation correction. In one exemplary embodiment a method and system for a broad-band fragmented aperture phased array antenna for the Ka, K, and/or Ku frequency band is presented. In one exemplary embodiment, the fragmented aperture design functions in one or more of the Ku-band, K-band, and/or Ka-band. In another exemplary embodiment, the antenna system may include full electronic polarization agility. In one exemplary embodiment, the antenna system may further comprise a printed circuit board radiating element. The printed circuit board radiating element may be configured to function as an antenna. In one exemplary embodiment, the antenna system may support operation over multiple frequency bands.

A partially dielectric loaded divided horn waveguide device for a dual-polarized antenna is described. The partially dielectric loaded divided horn waveguide device may include a polarizer, a waveguide horn, multiple individual waveguides dividing a horn port of the waveguide horn, and multiple dielectric elements partially filling the individual waveguides. The dielectric elements may include a dielectric member extending along a corresponding individual waveguide and one or more matching features for matching signal propagation between the partially dielectric loaded individual waveguides and free space. Various components of the partially dielectric loaded divided horn waveguide device may be tuned for enhanced signal propagation between the waveguide horn and the individual waveguides, and between the individual waveguides and free space.

In an example embodiment, an airborne radio frequency (RF) antenna device can comprise: a radiating portion; a waveguide portion connected to the radiating portion; a desiccant airflow channel; and an internal air volume located within the RF antenna device and associated with the desiccant airflow channel. The desiccant airflow channel can be integral with the RF antenna device. The internal air volume can be vented to the environment outside of the RF antenna device through the desiccant airflow channel.

A method, system, and device relating to a broad-band fragmented aperture tile and antenna system are disclosed. In one exemplary embodiment, an aperture tile comprises a plurality of unit cells. The plurality of unit cells individually comprise a driven radiating element layer, a module layer having a printed circuit board, wherein the module layer comprises one or more of a time delay module, a radio frequency distribution module, a radio frequency module, or a digital signal processor. Furthermore the aperture tile is coupled to a cold plate configured for heat transfer.

The present invention is directed to a circuit assembly that includes an integrated circulator assembly. The circuit assembly has a first substrate, which contains a continuous circuit trace that includes a circulator component from the circulator assembly and at least one electrical component from the circuit assembly. A second substrate is disposed beneath the first substrate and includes a cladding on one surface. The second substrate contains an aperture that accepts a ferrite element, which is axially aligned with the circulator component of the circuit trace. A conductive material is placed across the ferrite element so that it forms a continuous ground plane with the cladding, which is common to the entire circuit trace. The circulator assembly also contains a magnet bonded to the ferrite element. The circulator assembly may also include a yoke disposed below the magnet to shield the circulator from external magnetic fields.
