Analytical modeling and optimization of new Ku‐band tunable square waveguide iris‐post polarizer

Abstract: A novel design of the polarizer based on a square waveguide with four posts and four irises for Ku‐band 10.7–12.8 GHz is proposed. The main advantage of the developed polarizer design is the option to tune its polarization characteristics by variation of the posts height. The equivalent circuit of the polarizer has been obtained using scattering and transfer matrices technique. Using this model, the polarization and matching characteristics of the suggested polarizer were optimized simultaneously using the tru… Show more

“…Typically, polarization transformers and orthomode transducers are based on circular and coaxial waveguides [41], and square waveguides [42][43][44][45][46][47][48][49][50][51][52][53][54][55]. The main advantage of the iris polarization transformer is its most wideband operation compared to other designs.…”
