Latest Patents

Grosbois's latest patents include an antenna with circular polarization, specifically designed for antenna arrays. This innovative antenna system is capable of both circular and linear polarization, featuring a symmetrical stripline 90-degree hybrid coupler. The design incorporates first and second dipolar radiating elements, each with two quarter wave branches formed by folding the stripline conductors. The first dipolar element has its peripheral conductors folded in the same direction, while the second dipolar element is similarly configured. Additionally, a second 90-degree hybrid coupler connected in cascade allows for the selection of either rectilinear or circular polarization.

Another patent focuses on an antenna excited by a symmetrical strip line, which includes two peripheral conductors positioned above and below a central conductor. This design features a first dipolar radiating element with quarter wave branches and a second dipolar radiating element that is orthogonal to the first. The system also includes distributor and phase-shifter means to excite the dipolar radiating elements with similar signals that are phase-shifted by 90 degrees.
