Abstract: 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.

Abstract: 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.

Abstract: 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.
