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 controlled by phase change caused by transmitting through the periodic structure in slotted waveguide. The slot array antenna on a left-handed waveguide is designed to confirm the feasibility of the transmission line 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 pattern of fabricated antenna was measured and the characteristic of a left-handed transmission line was confirmed. Moreover, it was confirmed to be able to scan the beam direction by changing the length of the capacitive series stub. |
