PROBLEM TO BE SOLVED: To provide a directional beam antenna which provides an effective and precise directional transmission (and reception), is comparatively simple in configuration, and can be manufactured at a low cost. SOLUTION: This is a reconfigurable directional antenna which operates for transmission/reception of electromagnetic radiation (especially microwave and millimeter wave radiation). It is connected electromagnetically to an array of controllable antenna elements individually, and includes transmission lines each of which is oscillated by a transmission (or reception) signal having a controllable amplitude.
