Claim:
1. An antenna apparatus comprising: a glass plate that is fixed to a flange of a vehicle body at a window opening portion of the vehicle body; a dielectric material; a conductive film provided between the glass plate and the dielectric material; and a monopolar feeding portion provided on the dielectric material at a surface opposite to a glass plate side and at a position capable of being capacitively coupled to the conductive film, the antenna apparatus being configured such that a clearance between an end portion of the flange of the vehicle body and an outer edge of the conductive film functions as a slot antenna, the conductive film being provided with a notch having one end as an open end at the outer edge of the conductive film in the vicinity of the monopolar feeding portion, the conductive film is positioned to overlap the monopolar feeding portion projected on the glass plate side, and the monopolar feeding portion is capacitively coupled to the conductive film.
