The authors present the measured performance of a linearly polarized radial line antenna with reflection canceling slot sets. A model antenna was fabricated for the 12 GHz band with a diameter of 600 mm. The gain of 35.4 dBi and the antenna efficiency of 67% demonstrate good antenna operation. Further improvement of return loss is expected by the joint use of beam-tilt design and radome reflection.<
