An antenna device including: a first antenna assembly configured to receive first radiofrequency signals polarized according to a first polarization; a second antenna assembly configured to receive second radiofrequency signals polarized according to a second polarization orthogonal to the first polarization; and a radiofrequency signal handling assembly coupled with the first and second antenna assemblies, and configured to handle the received first radiofrequency signals separately from the received second radiofrequency signals.

Two-polarization switched-beam antenna for wireless communication systems

A tunable delay line for radiofrequency applications includes a waveguide and a dielectric perturbing member that is displaceable relative to the waveguide for varying the delay imparted by the line. The waveguide is a ridge waveguide and the perturbing member is arranged parallel to a longitudinal end surface of the ridge and is movable in the ridge plane, toward and away from the ridge end surface, or in a direction transversal to the ridge.

The waveguide polarizer is a device for microwave antenna systems consisting of a waveguide section, with circular cross-section, being equipped with two terminal flanges for connection to other circular guides. A certain number of elliptical irises are arranged inside at regular intervals, resting on parallel planes and all oriented in the same way, i.e. with their longer axes all belonging to the same axial plane.
