Design and Development of Ortho-mode Transducer in L-Band for Satellite Applications

This paper describes a compact Ortho Mode Transducer (OMT) design and implementation for L-band. Symmetric orthogonal polarizations in common port were isolated in other ports into single linear polarization. This system is implemented to operate S -band that can be used in applications for satellite technology. A flared waveguide section is often used to couple the symmetrical radio recurrence signal to a normal port. An optimized OMT handles the recurrence band of 1.9 GHz–2.1 GHz for direct port and integrated port. It is often intended to produce good scattering outcomes with computation techniques. The coefficients of reflection of each port across the L- band (1.9-2.1 GHz) is less than −10 dB. An enacted architecture has port-to-port isolation throughout the intended S-band better than 30 dB and the quantified insertion loss is around 0.4 dB across the optimal level frequencies. The CST tool was used for the optimization and simulation of OMT. The device is designed to accommodate satellite systems feed chain specifications for antenna.
