摘要:

提出了一种新的用于芯片内/芯片间无线通信系统中的基于人工磁导体(Artificial Magnetic Conductor,AMC)结构的单极子管脚天线阵列模型.印刷电路板(Printed Circuit Board,PCB)采用厚度3mm的FR4介质,形状为边长50mm正方形.4个单极子天线分布在PCB基板中心15mm×15mm的正方形各顶点上,代表4个芯片的4个管脚.天线为铜材质,长度2.6mm,直径1.5mm.在PCB介质中嵌入了一个周期性人工磁导体铜质平面,4个单极子天线形成一个4端口网络.在仿真基础上,进了实物加工测试.实测结果表明,具有AMC的天线阵列回波损耗(S11)-10dB频带为13.02GHz~15.73GHz;在14.22GHz处,S11的幅度达到最小值-27.25dB,S21S31S41分别为-26.26dB、-19.23dB、-21.14dB.与不含AMC结构的天线阵列相比,S参数得到了有效改善,其中S11改善了约3.63dB,S21S31S41分别提高了2.05dB、7.21dB、5.28dB.验证了在PCB介质中嵌入AMC结构,可以有效提高单极子天线间的电压传输系数,增加信号的功率传输增益.

Abstract:

A new type of monopole pin antenna array model based on an artificial magnetic conductor (AMC) structure is proposed in this paper,which will be potentially used in a wireless intra-/inter-chip (WⅡC) communication system.The PCB substrate is FR4 with the thickness of 3mm and its square area is 50mm by 50mm.On the PCB center,the four monopole antennas for four chips are mounted at the four corners of a square with dimensions of 15mm×15mm.The pin antennas are made of copper with the length of 2.6mm and the diameter of 1.5mm.A periodical AMC copper plane is embedded above the lower PCB plane.The four monopole antennas form a four-port network.Based on this WⅡC prototype simulation and prediction,its actual circuits are fabricated and measured.It is found that from the measurement the -10dB bandwidth of the return loss S11 ranges from 13.02GHz to 15.73GHz for this proposed antenna array.At 14.22GHz the magnitude of S11 reaches the minimum value of -27.25dB,and the measured S21,S31,S41 are -26.26,-19.23,and -21.14dB,respectively.In comparison to the antenna array without an AMC,the scattering parameters are improved effectively.The S11 is enhanced about 3.63dB and S21,S31,and S41 increase 2.05,7.21,5.28dB,respectively.Consequently,it is demonstrated that the embedded AMC structure in the PCB dielectric can significantly improve the signal voltage transmission coefficients between monopole antennas and increase the signal power transmission gains.
