Abstract (in Japanese) (See Japanese page) 
(in English) Left-handed transmission line supports waves with anti-parallel phase and group velocities. It has peculiar characteristic of backward leaky-wave radiation. Generally, we have phase delay in transmitting along the ordinary transmission lines. The traveling phase delay is canceled by the phase perturbation due to the periodic structure in transmission line and more phase advance achieves feature of left-handed transmission line. The purpose of this research is to improve design flexibility of array antenna operating on traveling-wave excitation. Beam direction can be controled by phase change caused by transmitting through the periodic structure in slotted waveguide. The slot array antenna with a left-handed waveguide is designed to confirm the feasibility in this paper. The antenna was composed of slots on a left-handed waveguide in which pairs of capacitive series stub on H-plane and inductive iris are periodically arranged to give the phase advance in the waveguide. Radiation characteristics of fabricated antenna was measured and the characteristic of a left-handed transmission line was confirmed. Wide beam scanning angle from forward to backward due to frequency change are confirmed experimentally.
