Abstract

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).
