Abstract
1. 인공 전자기 구조를 이용한 차세대 전파 센서 개발을 위하여 인공전자기구조 기반의파장 이하의 분해능을 갖는 원거리 이미징용 전파 렌즈, 소형안테나 및 광대역 고이득 안테나에 대한 설계 기술 연구를 수행하였음.
2. 원거리 이미징용 고분해능 전파렌즈에서는 인공전자기 구조를 기반으로 파장의 1/6 에 해당하는 해상도를 보이는 실린더형 원거리상 전파렌즈를 설계 및 제작함.
3. SRR 와 CRLH 구조를 이용하여 소형화 및 정합 달성. λ/33 x λ/33 (5mm x 5mm)크기의 소형 안테나를 설계함. 안테나의 동작 주파수는 이동통신 주파수 (1.75GHz ~ 1.87GHz)으로 설계됨. 안테나 효율과 -10dB 대역폭이 각각 80%, 6.35%로 우수한 성능을 보임
4. HGA( hybrid genetic algorithm) 을 이용한 FPC(Fabry—Perot cavity) 안테나 superstrate 의 배열 주기를 깸으로써 PCS 주파수 대역 내에서 15dB 이상의 이득을 1.59GHz~1.94GHz(19.8%) 대역에 걸쳐 얻음
