Title: Conceptual design of $X$ band waveguide dual circular polarizer

Article Details
Other Related Research

We present in this paper a new design of dual circular polarizer. This innovative design converts radiofrequency (rf) energy from TE10 mode in a rectangular waveguide to two polarized TE11 modes in a circular waveguide. A reflection less than ₋20 db is achieved and breakdown field is less than 42 MV/m at input of 1 MW. Meanwhile, this polarizer has a megahertz bandwidth, and the thermal stability is also discussed. This device can be used for broadcasting and receiving the circular polarized signals.
