平板裂缝天线阻抗匹配设计的研究

内容简介：本文对平板裂缝天线阻抗匹配设计方法进行了讨论。采用微波网络理论，在内部馈电情况下，分别对一条辐射波导上辐射裂缝的归一化导纳和为2的匹配设计准则，以及对串－并形式馈电装置，对耦合裂缝的归一化阻抗和为2的匹配设计准则进行了证明。按照同样方法，对串－串、并－串形式的馈电装置，导出了新的耦合裂缝匹配设计准则。

Abstract：The design method of impedance matching for planar slot antenna is discussed in this paper. The impedance matching criterion that the sum of all the radiating slot normalized conductances is equal to 2 for the inner feed, and also the sum of all the coupling slot normalized impedances for the series-shunt inner feeder is equal to 2 are verified by using microwave network theory. According to this method , a new matching criterion of coupling slots is derived for the series-series feeder and the shunt-series feeder.
