- W2022205144 abstract "본 논문에서는 집중소자인 캐패시터 및 저항을 사용하여 특성조절이 가능한 소형 역-F 안테나를 제안하였다. 캐패시터는 안테나 크기 및 공진주파수의 조절을 위해 안테나 종단과 접지면 사이에 삽입된다. 반면에 <TEX>$0{Omega}$</TEX> 저항은 접지면과 단락되는 선로를 대체하여 구현한 것으로써, 단락점의 위치 이동은 안테나의 입력임피던스를 변화시킬 수 있다. 따라서 구조의 재설계 없이도 적절한 캐패시터 및 단락점 위치 선택으로 최적의 안테나 특성을 얻을 수 있다. 이와 같은 본 논문의 타당성 검증을 위하여 2.4 GHz 대역용 안테나를 설계 및 제작하여 지그비 무선 리모컨의 한 제품에 적용하였다. 적용된 안테나의 크기는 <TEX>$8.5{times}4.5mm^2$</TEX>이며 재설계 없이도 대역폭 150 MHz 및 이득 2 dBi의 측정결과를 얻을 수 있다. In this paper, a small inverted-F antenna with adjustable characteristics is proposed with use of lumped elements, capacitor and resistor. Capacitor is inserted between end of the antenna and ground for size reduction and tuning of resonant frequency. On the other hand, <TEX>$0{Omega}$</TEX> resistor is replaced as the short line connected to ground. The movement of short point due to use of <TEX>$0{Omega}$</TEX> resistor results in providing variation of input impedance. Therefore optimum characteristics can be obtained only by proper choice of capacitor and short point without redesign of it's geometry. In order to check the validity, the proposed antenna is designed and fabricated for 2.4 GHz frequency band, and then is applied to a product of Zigbee wireless remote controller. As a result, the size of applied antenna is <TEX>$8.5{times}4.5mm^2$</TEX> and it is observed that the measured bandwidth and antenna gain are 150 MHz and 2 dBi respectively without redesign of the antenna." @default.
