摘要：

提出了一种基于蘑菇型电磁超材料构建的PCB(Printed Circuit Board)的芯片间/芯片内射频通信设计模型.该设计用单极子天线模拟芯片管脚,利用PCB介质作为通信信道,并填充一层超材料吸收多径传播中部分电磁波,降低天线回波损耗和改善天线之间相关度.分析电磁波在PCB介质内传播途径及超材料对其影响.对发射天线输入频率为20GHz不归零伪随机二进制信号,接收天线输出信号的眼图清晰端正.从频域和时域结果分析表明芯片-PCB无线互连可行,而且超材料能够明显改善通信信道而提高信号传输质量.

Abstract:

Based on an innovative two-layer PCB(Printed Circuit Board) medium,a monopole antenna is proposed for inter-chip wireless interconnection communications.The antenna is inserted into the PCB medium as an extended chip pin.The lower plate of the PCB is built up with a mushroom-type metamaterial to construct an electromagnetic wave absorbing layer.The interconnect communication model is analyzed and its scattering parameters are extracted.One antenna performs as a transmitter with a frequency 20GHz pseudo random binary signal with the high and low voltages at 1V and -1V,respectively.And others work as receivers whose received signals are represented through eye diagrams.The result shows that the mushroom-type metamaterial absorbs transmitted electromagnetic waves in the PCB medium,which reduces reflected waves and improves the system return loss for the two antenna system.In comparison with a metal supported PCB system,the eye-diagram derived for the metamaterial grounded PCB system can be improved.It is apparent that the proposed PCB system provides a good wireless inter-chip communication channel with the application of the absorbing feature of the metamaterials.

Key words: inter-chip wireless connection, metamaterial, chip's pin antenna, radio frequency communication, eye diagram
