Design a C_X Dual-band Dual-mode Rotary Joint
A novel C- and X- dual-band dual-mode rotary joint is proposed. The C-band rotary joint operated in TM<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">01</inf> mode and the X-band rotary joint operated in TE<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">01</inf> mode are united during the design. The two modes with orthogonal field components transmit in the circular waveguide simultaneously. The TM<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">01</inf> mode in the C -band is excited by a rectangular waveguide H plane T which is located at the end of the circular waveguide. The TE<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">01</inf> mode in the X -band is obtained by three rectangular waveguide E-plane Ts which are located at the side wall of the circular waveguide. The design results show that the rotary joint has a simple structure and a compact size. Meanwhile, the simulated reflection coefficients in dual-bands are superior to 20 dB.
