MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541123098 A) filed by Cvr College Of Engineering, Hyderabad, Telangana, on Dec. 6, 2025, for 'broadband septum polarizer for dual circular polarization for satellite earth stations.'
Inventor(s) include Ch V R S Gopala Krishna; and Dr L Nageswara Rao.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "Septum polarizer is a passive microwave component with broad bandwidth operating from 5.85 to 6.425 GHz for transmission of signals to satellite from earth station. The signals coming from the orthomode transducer are split into two equal halves and one of them is given a phase lead or lag of 90-degree by the introduction of the septum. At the end of the waveguide when these two components are added vectorially, the loci of electric vector from the loci of a circle resulting in circular polarization. The effectiveness of splitting the power into two equal halves and the phase shift provided by septum close to 90-degree determines the axial ratio. At the same time power impedance match provides low VSWR and surface finish the low insertion loss. The sense of polarization i.e. LHCP or RHCP is determined by phase lead or lag given to the signal split into two halves."
