Abstract

In this paper, a new split ring resonator using left-handed meta-material adapted in a bandpass filter with 2-stages is suggested. In this proposed bandpass filter, the size of the novel resonator can be easily controlled. Also, the bandwidth can be adjusted with the position of the tapped-line. The proposed resonator and filter has the center frequency of 10 GHz for I-band in military-satellite communication system with the Qe value of 184. The experimental results of the filter show that the insertion and return losses are 1.43 dB and 16.8 dB with bandwidth of 10 %, respectively.

본 논문에서는 메타 인공 물질을 이용한 스플릿 링 공진기를 새롭게 제안하여 2단 필터를 설계 하였다. 제안된 필터는 새로운 공진기의 크기를 자유롭게 조절할 수가 있고, 탭-선로의 위치를 이용하여 대역폭을 쉽게 조절할 수가 있다. 제안된 공진기 및 필터는 군사용 위성통신 대역인 I-밴드의 10 GHz 중심 주파수에서, 공진기의 Qe값은 184이며, 필터의 대폭은 10 %이고, 삽입손실 및 반사손실은 각각 1.43 dB 와 16.8 dB의 값을 얻었다.
