PROBLEM TO BE SOLVED: To provide a non-grounded terrestrial digital TV antenna which is plugged inside a side window glass of a vehicle, and acquires high sensitivity and stable receiving performance. SOLUTION: Grounding-side and hot-side feed points 3 and 4 are provided so as to be almost up and down near the middle part of the inner vertical edge of a flange of a fixed window glass 1. A vehicle glass antenna has a hot-side element that is constituted of one or more first horizontal leads which are extended from the hot-side feeding point in a direction apart from the vertical edge of the flange; one or more first vertical leads that are extended from the hot-side feeding point in the horizontal direction apart from the ground-side feeding point and along the vertical or inclined edge of the flange; and a ground-side element that is constituted of one or more second horizontal leads which are extended from the ground-side feeding point in the horizontal direction apart from the vertical edge of the flange, and a third horizontal lead which is extended from each end of one or more second vertical leads that are extended from the ground-side feeding point in a direction apart from the hot-side feeding point and along the flange in the horizontal direction apart from the vertical or inclined edge of the flange. Each feeding point is connected with the core of a coaxial cable and a sheath lead wire. COPYRIGHT: (C)2011,JPO&INPIT
