Abstract: A DTV receiving antenna device includes a case, a DTV receiving antenna. The case includes a top cover and a bottom cover. The antenna is situated in the case, including a metal conductor, a circuit board, a matching circuit and a conductive line. The metal conductor is disposed into the top cover. The circuit board is disposed into the bottom cover and includes a ground layer. The matching layer is formed on the circuit board, including a first metal part and a second metal part and a capacitance. The second metal part has a signal feeding point, and there is a gap formed between the first metal part and the second metal part. The capacitance is disposed on the gap and electrically connected to the first metal part and the second metal part. The conductive line is electrically connected to the first metal part and the metal conductor disposed into the top cover.
