摘　　要：对加载开路短截线的微带线的EBG特性及应用进行了研究。通过理论分析和实验证明其不仅表现出显著的阻带特性,还具有以下独特性质:阻带中心频率主要由短截线决定;周期长度可以远小于半波长;取适当参数,在特定阻带中心会出现衰减很小的尖峰。最后采用该结构研制了一个宽带低通滤波器。The EGB characteristics of a microstrip periodically loaded open-circuited stubs was analyzed and affirmed. Results of theoretical analysis and experiment indicate that the center frequency of stopband is determine by stubs, and the period-length which is far less than half wavelength. Moreover, it is found that a narrow passband could exist in some specific stop-band when parameters are proper. Based on this structure, a broad lowpass filter was developed.
