광대역 안테나는 DTV(디지털 지상파 텔레비전) 서비스에서 다양한 용도로 사용됩니다. 노트북 디스플레이 테두리를 따라 길고 좁은 공간에 배치하려면 소형 광대역 안테나가 필요합니다. 광대역 안테나를 구현하기 위한 후보 중 하나는 CRLH-TL(Composite Right/Left-handed Transmission Line)을 사용하는 누설파 안테나입니다. 그러나 UHF 대역용 CRLH-TL을 이용한 소형 누설파 안테나 설계 가이드라인은 부족한 실정이다. 본 논문에서는 광대역 및 간단한 구조를 위해 래더 네트워크로 구성된 CRLH-TL을 제안한다. 또한 이 논문에서는 DTV 대역에서 작동하는 CRLH-TL을 사용한 누설파 안테나 설계에 대해서도 논의합니다. CRLH-TL의 동작 대역폭과 감쇠 상수 사이의 관계가 논의됩니다. 이동 단말기의 제한적이고 좁은 공간에 수용할 수 있는 안테나가 설계되어야 한다. 따라서 안테나의 소형화를 목적으로 셀 수와 유한한 접지면의 영향을 논의한다. 본 연구에서는 제작된 안테나의 투과 및 방사 특성을 측정하였다. 제작된 안테나의 이득은 동작 주파수를 변화시켜도 거의 일정하게 유지되는 것을 확인하였다. 본 연구에서 달성된 최대 이득 및 작동 대역은 각각 약 -0.6dBi 및 약 54%입니다.

Abstract: Broadband antennas have various applications in digital terrestrial television (DTV) services. Compact broadband antennas are required for arranging in long and narrow space along the rim of a laptop display. A leaky-wave antenna using the composite right/left-handed transmission line (CRLH-TL) is one of the candidates for achieving the broadband antenna. However, there are not enough to design guideline of small leaky wave antennas using the CRLH-TL for UHF band. In this paper, a CRLH-TL comprising a ladder network is proposed for broadband and simple structure. The paper also discusses the design of a leaky-wave antenna with the CRLH-TL operating in the DTV band. The relation between the operating bandwidth and attenuation constant of the CRLH-TL is discussed. An antenna that can be accommodated in the limited and narrow space available in mobile terminals has to be designed. Hence, the effects of the number of cells and a finite ground plane are discussed with the purpose of achieving the miniaturization of the antenna. In this study, the transmission and radiation characteristics of the fabricated antennas are measured. The gain of the fabricated antenna is confirmed to remain almost constant even when the operating frequency is varied. The maximum gain and operating band achieved in this study are approximately -0.6 dBi and about 54%, respectively.

Compact broadband antennas are required for arranging in long and narrow space along the rim of a laptop display.

However, there are not enough to design guideline of small leaky wave antennas using the CRLH-TL for UHF band. In this paper, a CRLH-TL comprising a ladder network is proposed for broadband and simple structure.

The relation between the operating bandwidth and attenuation constant of the CRLH-TL is discussed.
