본 논문에서는 차량 앞유리에 탈부착이 가능한 다이폴 형태의 T-DMB 수신용 안테나를 설계하였다. 안테나의 구조는 동박과 급전선의 매우 간단한 구조를 가지며, 운전자의 시야에서 완벽히 벗어날 수 있도록 차량 유리의 테두리 쪽에 존재한다. 차체의 특성과 안테나의 입력 임피던스 특성을 고려하여 제안된 미앤더 형태의 다이폴 안테나는 T-DMB 주파수 대역(174~216 MHz)을 만족한다. Common Mode Stub를 추가한 Flexible 안테나는 차량 앞유리에서 부착되는 위치에 상관없이 안테나의 입력 반사 손실은 —5 dB 이하를 가지는 것이 가장 큰 특징이다.
