Abstract: An antenna system includes a first antenna operational to transmit a first radio-frequency signal, a second antenna operational to receive a second radio-frequency signal and receive the first radio-frequency signal, a first electromagnetic polarizer disposed between the first antenna and the second antenna and operational to change a polarization of the first radio-frequency signal, a second electromagnetic polarizer disposed between the first electromagnetic polarizer and the second antenna and operational to further change the polarization of the first radio-frequency signal, and a conductive ground plane disposed on a ground side of the first antenna and the second antenna. The conductive ground plane defines a gap between the first antenna and the second antenna. The gap extends under the first electromagnetic polarizer. The gap extends under the second electromagnetic polarizer. A horizontal component of the second polarization of the first radio-frequency signal is maintained across the gap.

Abstract: An antenna arrangement having a stacked layered structure. The antenna arrangement includes a radiation layer including one or more radiation elements, and a distribution layer facing the radiation layer. The distribution layer is arranged to distribute a radio frequency signal to the one or more radiation elements. The distribution layer includes at least one distribution layer feed and a first electromagnetic bandgap, EBG, structure arranged to form at least one first waveguide intermediate the distribution layer and the radiation layer. The first EBG structure is also arranged to prevent electromagnetic propagation in a frequency band of operation from propagating from the at least one first waveguide in directions other than through the at least one distribution layer feed and the one or more radiation elements. The distribution layer includes a plurality of distribution modules and a positioning structure, the positioning structure is arranged to fix the distribution modules in position.

Abstract: A filter component for an aircraft insert can include a non-conductive body having an outer surface and an inner surface. The inner surface can be configured to be hidden from view when installed on the insert. The filter component can include a surface filter disposed on the inner surface such that when the non-conductive body is installed on the insert the surface filter is not visible. The surface filter can be configured to filter out one or more predetermined filter frequencies.
