摘要： PROBLEM TO BE SOLVED: To obtain a small array antenna which can be used in a high frequency band of ≥1GHz, is wide in scanning range, and is higher in scanning speed than before. SOLUTION: A liquid crystal 23 is charged in the shape of a rectangular parallelepiped, and electrodes 27a and 27b are arranged on two side faces parallel to the zx plane of the rectangular parallelepiped. The two electrodes 27a and 27b are provided with lines, respectively, and an electric circuit is formed so as to apply a variably controllable voltage V2 between both of the electrodes. A grounding plate 26 is kept at a gorunding electrode (Ov). A wide width part 211a and a wide width part 211b are also connected with nearly similar lines, and each potential of them can be set variably to a desired voltage V1. Potentials of the wide width part 211 of a main line 21a and the wid width part 211b of a main line 21b are set to be the same values (V1) in any unit pattern 20 by using a circuit equivalent to the electric circuit.

摘要： PROBLEM TO BE SOLVED: To realize a small array antenna having a wide scanning range of beam directivity, and to realize a control means for freely changing a beam width and forming a null in a desired direction. SOLUTION: In each of unit patterns on a left half, all variable control members 14 are on positions moved in a positive direction of a y-axis by D. With this configuration, stubs 12 are completely covered by the variable control members 14 including branched portions in the middle part. Further, in each of the unit patterns of the left half, variable control members 13 are similarly driven by actuators 17', and gaps G1 of unit patterns are each completely covered with the variable control members 13. By doing such an operation, unit patterns in which stubs 12 or gaps G1 are covered with the variable control members 13, 14 do not operate as a minute antenna. Thus, a band gap is formed on the left half of the antenna. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To realize a downsized array antenna with so wider scanning zone as to be able to be used even at higher frequency range than 1 GHz. SOLUTION: The state diagram Fig. 4-B represents a state in which, at a point of application, an actuator 27 has depressed a change responding follow-up mechanism 28 to a lower portion on the diagram. As the result of the depressing action, since the change responding follow-up mechanism 28 turns around a supporting point 29, the working point moves upward with a result that a dielectric 23 also moves upward in parallel with the working point. In this unitary pattern 20, a distance between the working point and the supporting point is longer than that between the point of application and the supporting point. Therefore, in this turning movement, the resulting moved distance of the dielectric 23 has become longer than a distance arising from depressing the point of application by the actuator 27. In other words, by setting the relationship among the three points, i.e., the point of application, the supporting point and the working point, as described above, the change responding follow-up mechanism 28 is given an amplifying function for amplifying the action of the actuator 27.

解决方案：状态图图4-B表示在施加点处致动器27已经将改变响应跟随机构28压到图的下部的状态。作为按压动作的结果，由于变化响应跟随机构28绕支撑点29转动，工作点向上移动，结果电介质23也与工作点平行地向上移动。在该单一图案20中，工作点和支撑点之间的距离比施加点和支撑点之间的距离长。因此，在该转动中，电介质23的移动距离变得比由致动器27压下施加点所产生的距离长。换句话说，通过设定三点之间的关系，即点如上所述，变更响应跟随机构28具有用于放大致动器27的作用的放大功能。（C）2006年，JPO和NCIPI
