【 摘 要 】

This paper studies design of a full-band waveguide polariser using iris for satellite communications. Operation theory and design parameters of a full-band polariser are introduced, and a systematic design method has been proposed. The performance of the polariser is analysed using the well-known commercial electromagnetic simulation software high-frequency structure simulator. Using the proposed method, a full-band polariser operating in WR-22 waveguide band (33–50 GHz) is designed, fabricated and tested. Measurements of the fabricated polariser show that the phase difference is <10° as a reference point by 90°, the axial ratio is <1.3 dB, insertion loss is <0.1 dB and return loss is >25 dB in the required overall band.
