초록

본 논문에서는 지능형 주차검지센서에 장착하기 위한 ISM-대역(중심주파수 447 MHz) 소형화된 역 F 안테나를 제안하였다. 먼저 제한된 크기를 가진 지능형 주차검지센서 모듈(72 mm × 70 mm)내에 안테나를 내장하기 위해, ISM-대역의 낮은 주파수 447 MHz(파장 λ : 670mm)에서 폴디드 형태의 역 F 안테나를 설계하였다. 그 결과, ISM 대역(중심주파수 447 MHz)에서 공진하며, -10 dB 대역폭 13 MHz(2.9%)로 적합한 특성을 얻었다. 또한, 수직·수평소자에 의한 H-plane 패턴은 null point가 제거된 전방향성 패턴을 나타내며, E-plane은 특정 방향으로 지향성을 가지므로, 주차장에서의 차량 관리용 안테나로써 적합함을 확인하였다.

In this paper, we proposed a miniaturized folded inverted F antenna with ISM-band (center frequency : 447 MHz) for mounting in intelligent parking sensor. First, to mount the antenna in the intelligent parking sensor module (72 mm × 70 mm) with limited size, a folded inverted F antenna was designed at low frequency 447 MHz (wavelength λ : 670 mm) of the ISM-band. As a result, it resonates in the ISM band and obtains suitable characteristic with a -10 dB bandwidth of 13 MHz (2.9%). In addition, the H-plane pattern by the vertical and horizontal elements represents the omni-directional patterns from which the null point is removed, and the E-plane has directivity in a specific direction. Finally, it is suitable as and antenna for vehicle management in parking lots.
