    • It is an object of the invention to provide an antenna with small side-lobe while narrowing the beam width to a desired one without the antenna increased in weight. Besides, it is also an object of the invention to decrease the manufacturing process less than ever before and reduce the cost. Furthermore, it is also an object of the invention to improve stability when the antenna is turned.In order to solve the above-mentioned problems, the antenna of the invention is characterized by comprising a radiator which is configured to radiate electromagnetic wave inside of an antenna housing, at least one dielectric which is configured to be contributory to directivity angle of the electromagnetic wave in the vertical direction, and characterized in that the dielectric is attached to the antenna housing ahead of the radiator.
    • 本发明的目的是提供一种具有小侧波瓣的天线,同时将波束宽度变窄到所需的波长,而天线的重量增加。 此外,本发明的另一个目的是减少制造过程比以往更少,并降低成本。 此外,本发明的另一个目的是提高天线转动时的稳定性。 为了解决上述问题,本发明的天线的特征在于包括:散热器,其被配置为辐射天线壳体内部的电磁波;至少一个电介质,被构造成与电磁波的方向角有关 在垂直方向上波动,其特征在于,所述电介质附着到所述散热器前面的天线壳体。

    • A process for producing a periodic structure comprises the steps of preparing a working object, the property of which changes in view of a photoreaction caused by an exciting energy, generating a light having a photonic energy of intensity of one fraction of natural number divisions of the exciting energy by each of the light sources of light-source groups arranged regularly in a two-dimensional arrangement, and concentrating the light emitted from the light source group at each of the light-concentrating points arranged at regular intervals in the working object to cause a photoreaction at and around the light-concentrating point to form a periodic structure comprised of regions each of which has a changed property in the working object.
    • 制造周期性结构的方法包括以下步骤:准备加工对象,其特性是由激发能量引起的光反应的变化,产生光强度为自然数分割的一部分的光子能量的光 通过以二维排列规则地排列的每个光源组的每个光源激发能量,并且将从光源组发射的光聚集在工作对象中以规则间隔排列的每个聚光点,使得 在光聚集点处和周围的光反应以形成由工作对象中具有改变的性质的区域组成的周期性结构。
