Latest Patents

Morin's latest inventions include the "Orientable Antenna with Conservation of Polarization Axes" and the "Three-Access Polarization and Frequency Duplexing Device".

The orientable antenna is distinguished by its ability to be directional, serving both transmit and receive functions. It integrates at least one reflector and a source of electromagnetic radiation, equipped with mechanisms for exciting the source in two orthogonal linear polarizations. The mechanical system enhances the antenna's rotation while ensuring that the source remains fixed, thereby conserving the orientation of the polarization axes. The design employs a parabolic main reflector and a hyperbolic auxiliary reflector in a Cassegrain configuration, which is particularly beneficial in applications pertaining to radar, direct broadcast satellites, and telecommunications that utilize frequency reuse through polarization diversity—especially in space and airborne contexts.

The three-access polarization and frequency duplexing device includes a common circular waveguide that manages two polarizations within a low-frequency band and one polarization within a high-frequency band. This device's innovative design provides an efficient pathway for frequency management, featuring a secondary rectangular waveguide that aligns its narrow sides with one low-frequency band polarization. A critical short-circuit plate facilitates optimal wave alignment and performance.
