Circular Waveguide Polarizer for Weather Radars and Satellite Information Systems

This research presents the design and main electromagnetic characteristics of novel compact microwave waveguide polarizer. The developed device's structure is based on a circular anti-phase conducting posts located in it. application instead square one allowed simple integration polarizer with corrugated horn antennas. obtaining required phase difference using posts-based provides possibility fine tuning after its manufacturing process. In addition, simultaneous adaptive operation at orthogonal linear polarizations available antenna system including posts. An automatic control height must be applied order to provide this option. Numerical simulation, optimization, manufacture measurements polarizer's were carried out operating band 7.4-8.5 GHz. Measured proved that suggested good matching polarization performance. Developed can integrated systems modern weather radars satellite information systems.
