Other Abstract

The invention relates to an L-band four-ridge ortho-mode transducer. The ortho-mode transducer is a modified index gradually-changing curve loaded with ridge diaphragms and a coaxial excitation structure, the operating frequency is 1-2GHz, and the ortho-mode transducer is applied to a radio telescope L-band receiver system. The ortho-mode transducer is composed of a circular waveguide, a four-ridge waveguide gradually-changing transformation segment, a four-ridge circular waveguide, ridge diaphragms, a short-circuit back cavity, a first coaxial probe and a second coaxial probe, and is characterized in that the diameter of the circular waveguide is designed according to the lowest operating frequency; the four-ridge waveguide gradually-changing transformation segment selects a modified index gradually-changing type impedance transformation mode so as to ensure transmission from a dominant mode of the four-ridge circular waveguide dominant mode to a dominant mode of the circular waveguide; chamfer modification is performed on the four-ridge cross section inside the four-ridge circular waveguide so as to ensure that a phenomenon of mutual interference between the ridge diaphragms does not occur; and a four-ridge waveguide coaxial transformer adopts a coaxial feed mode, and the short-circuit back cavity thereof selects a conical design. Measurement and simulation results of the ortho-mode transducer in reflection loss and isolation are basically identical, and radio astronomical observation requirements can be met.
