| 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. |
