초록

본 논문은 MNG (mu-Negative) 메타 인공 물질을 이용한 T-SRR (Triple Split Ring Resonator)을 제안하여 3단의 저손실 대역통과 필터를 응용 설계를 하였다. 제안된 대역통과 필터는 낮은 유전율을 가진 기판 위에 T-SRR의 크기를 자유롭게 조절할 수 있고 ${\lambda}/4$ 전송선로를 적용하여 저손실 대역통과필터로 응용설계함. 또한 군사용 위성통신대역의 I-밴드 10 GHz 중심 주파수에서, 필터 내의 T-SRR의 QL값은 184이며, 필터의 대역폭은 10 % 일 때, 삽입손실 및 반사손실은 각각 1.44 dB 와 17.3 dB의 값을 얻었다. 향후 IPD(Integrated Passive Device)등으로 재설계가 가능할 것임.

In this paper, the T-SRR (Triple Split Ring Resonator) using MNG (mu-Negative) meta-material adapted in a low-loss bandpass filter with 3-stages is suggested. The size of the T-SRR in the proposed bandpass filter with low dielectric constant PCB can be easily controlled. And the ${\lambda}/4$ transmission line theory is applied. The proposed T-SRR and filter have the center frequency of 10 GHz with QL value of 184 for military-satellite communication system in I band. The experimental results of the filter show that the insertion and return losses are 1.44 dB and 17.3 dB with bandwidth of 10 %, respectively. The proposed filter will be redesigned by IPD material etc. should be placed here. These instructions give you guidelines for preparing papers for JICCE.
