Abstract: An orthomode junction for separating and/or combining orthogonally-polarized radiofrequency wave signals, comprises a body which has a main cavity forming a main waveguide, which has a blind end, and auxiliary cavities forming auxiliary waveguides, which communicate laterally with the main cavity in the vicinity of the blind end thereof, and a deflection insert situated at the blind end of the main cavity and facing the auxiliary cavities, the deflection insert having different shapes on the side of the auxiliary cavities respectively.

Abstract: An integrated optoelectronic or optical device is formed by a polarization-splitting grating coupler including two optical waveguides, a common optical coupler and flared optical transitions between the optical coupler and the optical waveguides. The optical coupler is configured for supporting input/output of optical waves. A first region of the optical coupler lies at a distance from the flared optical transitions. The first region includes a first recessed pattern. Second regions of the optical coupler lie between the first region and the flared optical transitions, respectively, in an adjoining relationship. The second regions include a second recessed pattern different from the first recessed pattern.

Abstract: A connector includes a first antenna configured to transmit first signals in a first direction and with a first polarization, a second antenna coupled to the first antenna and configured to transmit second signals in a second direction that is parallel to the first direction and with a second polarization that is orthogonal to the first polarization, and a third antenna coupled to the first and second antennas and configured to transmit third signals in a third direction that is parallel to the first direction and with the first polarization, wherein the second antenna is positioned between the first and third antennas.

Abstract: A coplanar waveguide electronic device is formed on a substrate. The waveguide includes a signal ribbon and a ground plane. The signal ribbon is formed of two or more signal lines of a same level of metallization that are electrically connected together. The ground plane is formed of an electrically conducting material which includes rows of holes.
