<P>PROBLEM TO BE SOLVED: To provide a frequency dispersion line capable of setting a main beam direction for respective different frequency bands. <P>SOLUTION: The frequency dispersion line includes: a metal ground plate; N (N≥2) first metal plates arranged on a first plane parallel with the metal ground plate in an array at predetermined intervals, and opposed to the metal ground plate; N short-circuit lines short-circuiting the metal ground plate and the respective first metal plates; two lines drawn at both ends of the array of the first metal plates at predetermined intervals with the metal plates positioned at both ends respectively, and drawn in the array direction; N-1 second metal plates arranged in a second plane parallel with the metal plates in an array at predetermined intervals, the second metal plates being arranged so that a projection of the second metal plates on the first plane partially overlap with two adjacent first metal plates, and the second plane being positioned between the metal ground plate and the first plane or the first plane being positioned between the metal ground plate and second plane. <P>COPYRIGHT: (C)2013,JPO&INPIT |
