Rectangular/circular-to-radial waveguide transformers through a ring slot have been proposed for the feeder of radial line slot antennas(RLSAs)in millimeter wave application. Rotating electric modes are excited by a set of ring slot and perturbation dog bone slot. Basic operation is observed in 12GHz band. Concentric array radial line slot antennas fed by these transformers are fabricated and the antenna gain of 26.9dBi with the efficiency more than 60% is measured. The applicability for millimeter wave is verified for 38GHz band RLSA fed by the rectangular waveguide. The measured gain of the antenna is 22.5dBi with the efficiency of 53% with the diameter of 46mm and 26.4dBi with 61% with the diameter of 66mm.
