研究目的
Designing resonators with high group delay for modern microwave telecommunication systems, especially in low phase noise oscillators.
研究成果
The paper concludes with the successful design and fabrication of three novel dual-band passive high group delay complementary split-ring resonators (CSRRs). The resonators demonstrate high Q-factor and group delay, making them suitable for applications in low phase noise oscillators, filters, and diplexers.
研究不足
The study focuses on a specific frequency range (4.5–5.5 GHz) and the resonators' performance may vary outside this range. The practical implementation may require precise fabrication techniques.
