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(S_(11))-10d B频带为13.02GHz~15.73GHz;在14.22GHz处,S_(11)的幅度达到最小值-27.25d B,S_(21)、S_(31)、S_(41)分别为-26.26d B、-19.23d B、-21.14d B.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S_(11)改善了约3.63d B,S_(21)、S_(31)、S_(41)分别提高了2.05d B、7.21d B、5.28d B.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.
A new monopole antenna array model based on artificial magnetic conductor (AMC) is proposed for the IC / IC wireless communication system. Printed Circuit Board (PCB) The thickness of 3mm FR4 medium, the shape of the side length of 50mm square .4 monopole antenna distributed in the center of the PCB substrate 15mm × 15mm square vertices, representing four pins of the four chips. Antenna is made of copper, length 2.6mm, diameter 1.5mm. Embedded in the PCB medium, a periodic planar magnetic conductor of the magnetic conductor, 4 monopole antenna to form a 4-port network. Based on the simulation, into the physical processing test. The measured results show that, The antenna array return loss with AMC (S_ (11)) - 10d B band is 13.02GHz ~ 15.73GHz; at 14.22GHz, the amplitude of S_ (11) reaches the minimum value of -27.25d B, S_ (21) (31) and S 41 (41) respectively -26.26d B, -19.23d B and -21.14d B. Compared with the antenna array without AMC structure, the S-parameters are effectively improved, and S 11 is improved About 3.63d B, S 21, S 31 and S 41 increased by 2.05d B, 7.21d B and 5.28d B. It is verified that the AMC structure is embedded in the PCB medium , Which can effectively improve the voltage transmission coefficient between monopole antennas and increase the signal transmission power gain.
