Abstract
본 논문에서는 휴대 방송용 기기에 적합한 다중 대역 및 광대역 안테나를 제안한다. 제안된 안테나는 두 복사체의 공진 주파수를 인접시킴으로써 DVB-H 서비스 대역에서의 광대역 특성을 만족시키고, 체배 주파수를 이용하여 DAB 서비스 대역에서 동작 가능케 한다. 3개의 공진 주파수 조정함에 있어서 상호 영향이 적기 때문에 비교적 쉽게 대역폭을 만족시킬 수 있다. 제작된 안테나는 DVB-H 서비스 대역인 <TEX>$470{\sim}740\;MHz$</TEX>와 DAB 서비스 대역인 <TEX>$1,450{\sim}1,480\;MHz$</TEX> 대역에서 VSWR 2:1 이하의 특성을 가지며, 각각 <TEX>$1.97{\sim}4.10\;dBi$</TEX>와 <TEX>$1.98{\sim}2.04\;dBi$</TEX>의 최대 이득 특성을 갖는다. The multi-band and wide-band antenna for a portable broadcasting terminal is proposed. The proposed antenna consists of two radiators with a parallel structure. The antenna has an enough wide impedance bandwidth for the DVB-H(Digital Video Broadcasting-Handheld) service band since two radiators have adjacent resonance frequencies and operates in the DAB(Digital Audio Broadcasting) service band using the third harmonic of the radiator 1. The fabricated antenna has VSWR characteristics of less than 2:1 in the frequency band <TEX>$470{\sim}740\;MHz$</TEX> for DVB-H and <TEX>$1,450{\sim}1,480\;MHz$</TEX> for DAB. The measured peak gain of the antenna is <TEX>$1.97{\sim}4.10\;dBi$</TEX> in the DVB-H band and <TEX>$1.98{\sim}2.04\;dBi$</TEX> in the DAB band.
