一种新型一维微带PBG单元结构

A Novel 1-D PBG Cell Structure Microstrip Transmission Line

通过对传统二维微带 PBG 结构的研究,针对微带线的传播常数是微带线相对于接地板上周期孔眼的两个主轴的位置和方向的敏感参数而不能根据实际情况任意布线的缺点,提出了一种新型一维微带 PBG(photonic bandgap)单元结构及其等效 L-C 电路模型。本文提出的 PBG 传输线可以应用于微波集成电路中,能够减小电路尺寸,且可以抑制高次谐波的产生。

In the study of a traditional 2-D microstrip PBG structure, it is found that the propagation constant strongly depends on the orientation and location of the line with respect to the two principal axes of the periodic perforation. A novel one-dimensional microstrip photonic bandgap （PBG） cell structure and an equivalent L-C circuit used to model the PBG cell are proposed. The proposed PBG transmission line PBG cell is used in the microwave integrated circuits for size reduction and rejection of higher-order harmonics.
