摘要： PROBLEM TO BE SOLVED: To provide an antenna device in which degradation of antenna characteristics, e.g., expansion of beam width or decrease in front back ratio, can be minimized while reducing the weight of a reflective plate of meta-material structure.SOLUTION: Since the dielectrics 121, 131 of meta-material reflective plates 120, 130 have cavities 123, 133 formed in the longitudinal direction, the volume is 75% or more and less than 100% when compared with the volume of solid reflective plates. Since the cavities 123, 133 penetrate the dielectrics 121, 131, weight of the meta-material reflective plates 120, 130 can be reduced. But since the volume of the meta-material reflective plates 120, 130 is 75% or more that of solid reflective plates, expansion of beam width of an antenna device 100 can be prevented. Furthermore, since the cavities 123, 133 are formed on the outside of the central parts 122, 132 of a cross-section orthogonal to the longitudinal direction of the dielectrics 121, 131, decrease in front back ratio of the meta-material reflective plates 120, 130 can be prevented.
摘要翻译：要解决的问题：为了提供天线特性的劣化（例如，波束宽度的扩大或前后比的减小）可以最小化，同时减少超材料结构的反射板的重量。解决方案：因为超材料反射板120,130的电介质121,131具有沿纵向方向形成的空腔123,133，与固体反射板的体积相比，体积为75％以上且小于100％。由于空腔123,133穿透电介质121,131，所以可以减少超材料反射板120,130的重量。但是，由于超材料反射板120,130的体积为固体反射板的体积的75％以上，因此能够防止天线装置100的波束宽度的膨胀。此外，由于空腔123,133形成在与电介质121,131的纵向正交的横截面的中心部分122,132的外侧，所以超材料反射板120的前后比的减小，130可以防止。

摘要： PROBLEM TO BE SOLVED: To solve the problem that a radar-use antenna device, in which a primary radiator using a coaxial line is fixed to a feed line and a reflection mirror is rotated at the outer circumference of the primary radiator, becomes expensive because the number of components is increased when being made high in gain and that the high output of a radar device is limited because transmission loss is increased in a high frequency by using the coaxial line and power-proof characteristics are more degraded than that in a waveguide path. SOLUTION: A waveguide is used for a feeding path, and an electromagnetic horn is used for a radiating part as a fixed primary radiator 12. A conical reflector is installed at an upper part of the electromagnetic horn, and an antenna forms a horizontally non-directional beams when the conical reflector reflects a beam by the electromagnetic horn. Reflectors (main and sub reflectors) 11a and 11b are rotated at the outer circumference of the primary radiator. COPYRIGHT: (C)2008,JPO&INPIT
