摘要

研究了宽带偶极子天线在电磁带隙反射器上的辐射特性。采用蘑菇状的EBG结构作为EBG反射器。采用矩量法进行分析。结果表明，得到了驻波比(VSWR)的宽带特性。然而，即使使用宽带EBG反射器，也不一定能在宽频率范围内获得良好的辐射方向图。随后，分析了辐射机理。分析结果表明，辐射图的形状取决于电子束贴片的尺寸。

Radiation characteristics of a wide-band dipole antenna over an electromagnetic band-gap reflector

Radiation characteristics of a wide-band dipole antenna over an electromagnetic band-gap (EBG) reflector are investigated. The mushroom-like EBG structure is used as the EBG reflector. The analysis is performed using Method of Moment. It is shown that wideband characteristics of the voltage standing wave ratio (VSWR) are obtained. However, good radiation patterns in the wide frequency range are not always obtained even though the wideband EBG reflector is used. Subsequently, the radiation mechanism is analyzed. The analysis results show that the shape of the radiation pattern depends on the dimension of the EBG patch.
