본 논문에서는, Glass 안테나의 특성과 휴대성 및 제작상의 장점이 있는 다이폴 형태의 Flexible T-DMB 안테나를 제안하였다. 차량의 전면 유리 최외각에 위치하는 안테나를 구현하기 위하여 차체의 영향에 따른 안테나의 특성과 안테나의 부착 위치에 따라 달라지는 안테나 특성을 고려하여 급전 선로 사이에 매칭 회로를 추가하여 안테나의 입력 정합 특성을 높였다. 차량의 전면 유리에서의 실험 결과, T-DMB(174~216 MHz) 대역에서 안테나의 입력 반사 손실은 —6 dB 이하를 기준으로 모두 만족하였으며, 위치 변화에도 T-DMB 대역을 만족하였다.
