The invention pertains to an electronic sweep device with integrated active lens and light source. The device includes a bundling of superimposed channels C which are separated by thin metal planes P that include, in front of a metal short-circuit plane (10), illumination organs (S) and phase displacement organs (B). The invention makes it possible to create a compact electronic sweep device which eliminates the parasitic reflection phenomena between illuminator and lens for the purpose of controlling a hyperfrequency beam.

Electronic sweep device with active lens and integrated light source

A method and apparatus for directionally coupling two technically different microwave transmission lines, one being a waveguide and the other a stripline, in which a central conductor of the stripline is plunged into waveguide through a slot in a wall of the waveguide and loaded by capacitors or inductors. The width of the central conductor and values of the capacitors and inductors determines the desired coupling coefficient.
