    • A vehicular glass antenna includes a core wire-side power supplying section (20), a core wire-side antenna element (30) electrically connected to the core wire-side power supplying section, a ground-side power supplying section (40), and a ground-side antenna element (50) electrically connected to the ground-side power supplying section. The core wire-side antenna element includes a core wire-side first element (31) and a core wire-side second element (32). The core wire-side first element extends from the core-side power supplying section as a starting point along an edge of a window opening (5) of a vehicle body (1) in such a manner as to keep a first predetermined distance relative to a closest part of the edge of the window opening. The core wire-side second element extends from the core wire-side first element in a substantially vertical direction at a position (h1) separated by more than a prescribed distance from each of left and right edges (5b, 5d) of the window opening. The ground-side antenna element has a ground-side first element (51) extending from the ground-side power supplying section as a starting point along the core wire-side first element in such a manner as to keep a second predetermined distance relative to the core wire-side first element.

    • A vehicular glass antenna that allows disposition of a DAB antenna having an AM antenna is disclosed. The glass antenna (30) includes a first antenna (31) having a plurality of horizontal elements (31 a to 31l) and vertical elements (33a, 33b), and a second antenna (32) capacitatively coupled with a topmost one (31 a) of the horizontal elements of the first antenna and arranged in an upper part of a region in which the first antenna is mounted. The first antenna includes the topmost horizontal element (31 a), a first vertical element (33a) held in contact with the topmost horizontal element (31 a), and a second vertical element (33b). The first vertical element (33a) and the second vertical element (33b) are disposed so as to be substantially in parallel across a gap (d) for which the reception sensitivity of each of the first antenna (31) and the second antenna (32) is set to be in an optimal range, and a slit (33) having a predetermined height is formed by the gap (d). An electrical connection is established at a bottommost end of each of the first vertical element (33a) and the second vertical element (33b).
