Abstract: A connection arrangement comprises an antenna adapted to transmit and/or receive electromagnetic waves and a waveguide member adapted to transport the electromagnetic waves. An end section of the waveguide member is arranged at the antenna in a transmission state such that an electromagnetic radiation can be transmitted between the antenna and the waveguide member. The waveguide member has a recess extending from a free end of the waveguide member into the waveguide member. The antenna is at least partially inserted in the recess in the transmission state.

Abstract: An antenna comprises a pair of planar layers that are stacked in a direction perpendicular to a pair of layer planes along which the pair of planar layers extend and a separation layer at least partially separating the pair of planar layers. The pair of planar layers each end at a common layer end face and each provide a waveguide for transmission of electromagnetic waves parallel to the pair of layer planes. The waveguides end at the common layer face.

Abstract: A switching module for establishing a controllable propagation path for a high-frequency modulated signal in response to a switching information comprises a controllable switch and a link-management unit. The controllable switch is adapted to couple a first port to one of a second port and a third port. The link-management unit is operable to generate a control signal for controlling the switch based on the switching information. The link-management unit has a detector unit adapted to receive the control signal with the high-frequency modulated signal and to generate a pulse for controlling the switch depending on the control signal.
