英文摘要:

      In order to realize a highly integrated on-chip reconfigurable antenna system, this paper employs silicon-based 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.
