| A new mode transducer for converting the TE10 rectangular waveguide mode to the TM01 circular waveguide mode is presented. The novel topology is based on two T-type junctions with in-phase excitation at their input rectangular ports. The ?rst one is an H-plane T-junction in rectangular waveguide. The second one differs from the standard E-plane T-junction in the excitation, which is carried out by modes excited with ?elds having the same in-phase polarization at the input rectangular ports, and has the output port in circular waveguide. This con?guration exploits the symmetry of the modes under consideration to achieve a high-purity conversion, controlling the propagating circular waveguide TE11 mode to a maximum level of -42 dB in the whole operation band. The design bandwidth is 2 GHz centered at 12 GHz with a return loss level higher than 28 dB. In addition, the transducer can be divided in a main body plus a cover for easing the manufacturing. In order to verify the proposed geometry, a back-to-back arrangement has been measured connecting two similar aluminum transducers with four different angles between their rectangular ports (0?, 45?, 90?, and 180?). The excellent experimental results validate the novel transducer with a measured converting ef?ciency higher than 98:2% in a 16:7% relative frequency bandwidth. | |
