초록

본 논문에서는 직렬 inter-digital 커패시터와 이중 병렬 인덕티브 쇼트 스텁으로 구성된 double negative(DNG) 전송 선로를 설계하였다. 이러한 DNG 전송 선로는 특정한 주파수 이상에서는 double positive(DPS) 전송 선로의 특성을 가진다. 다시 말해서, 설계된 전송 선로는 DNG와DPS전송 선로의 특성을 주파수에 따라서 동시에 가진다. 누설파 대역에서의 DPS/DNG 전송 선로는 주파수 스캐닝 안테나로 이용되어 질 수 있다. 대칭 누설파 안테나의 분산 특성과 원거리 방사 패턴을 모의실험하였고 제작 및 측정하였다. 모의실험 결과는 측정결과와 대략 일치하였다.

In this paper, we have designed artificial double negative(DNG) transmission line composed of series inter-digital capacitor and two shunt inductive short stubs. This artificial DNG transmission line has the property of double positive (DPS) transmission line over some frequency ranges due to RF nature. In detail, this transmission line simultaneously has the contrary properties of DNG and DPS transmission line depending on operation frequency. DPS/DNG transmission line at leaky region is utilized to design frequency scanning antenna with backfire-to-endfire. We have simulated and measured the dispersion and for-field radiation beam patterns of symmetrical leaky wave antenna. The results show rough agreement.
