摘　　要：为了实现高度集成化的片上可重构天线系统,利用硅基固态等离子体表面PIN(S-PIN)二极管技术,设计了一种C—Ku波段频率可重构的领结型缝隙芯片天线。文中讨论了利用S-PIN二极管作为芯片天线频率可重构部件的设计标准,并对S-PIN二极管的结构参数进行了分析。通过控制S-PIN二极管的截止/导通状态,提出的缝隙芯片天线可以实现从6.7 GHz到17.97 GHz的工作频率可重构,增益分别为4.63 dBi和3.4 dBi。在实际的流片和测试过程中发现,文中研制的S-PIN二极管具有良好的伏安特性。此外,固态等离子体天线工作在C波段和Ku波段时的实际中心工作频点分别位于6.6 GHz和17.9 GHz,与仿真结果相比具有良好的一致性,验证了S-PIN二极管在制造频率可重构芯片天线方面的潜力。In order to realize a highly integrated on-chip reconfigurable antenna system,this paper employs siliconbased solid-state plasma surface PIN(S-PIN)diode technology to design a bowtie-shaped slot chip antenna capable of frequency reconfiguration across the C to Ku bands.The article discusses the design criteria for utilizing the S-PIN diode as a frequency-reconfigurable component in chip antenna and analyzes the structural parameters of the S-PIN diode.By controlling the off/on states of the S-PIN diode,the proposed slot chip antenna achieves frequency reconfiguration for operation at 6.7 GHz and 17.97 GHz,with gains of 4.63 dBi and 3.4 dBi,respectively.The S-PIN diode developed in this study exhibits excellent current-voltage characteristics during the chip tape-out and testing processes.Furthermore,the central operating frequencies of the solid-state plasma antenna in the C and Ku bands are measured to be 6.6 GHz and 17.9 GHz,respectively,which exhibit good agreement with simulation results,thereby validating the potential of S-PIN diodes in manufacturing frequency-reconfigurable chip antennas.
