摘要
根据小型化的要求,提出了可以用于小型化L波段磁绝缘线振荡器的一体化辐射天线的模型,即介质+插板移相型模式变换器,该模型可以有效缩短模式变换器的物理长度,并基于该模型研究了一体化辐射天线的方向图、增益、物理长度等特性,初步优化设计了一体化辐射天线,为结构紧凑的小型化磁绝缘线振荡器的研究提供了方便。
According to the requirement of miniaturization, a kind of radiation antenna model integrated with mode converter for the compact L-band magnetically insulated transmission line oscillator（MILO） is put forward. The model uses dielectric and metal board for phase shift. It can greatly shorten the physical length of the mode converter. Based on this model, an integrated radiation antenna is investigated. The radiation antenna is designed and optimized by numerical calculation. The antenna’s characteristics such as far-field patterns, gains and physical length are also obtained.
