An automotive glass antenna includes (a) a defogger having first and second bus bars; (b) a first L-shape auxiliary element connected to a lower end of the first bus bar; (c) a second L-shape auxiliary element connected to an upper end of the second bus bar; (d) a feed point provided at a position near an upper portion of the first bus bar or a lower portion of the second bus bar; and (e) a main element that includes a main vertical element extending along an outside of the first or second bus bar to achieve a capacitive coupling therewith and a main horizontal element extending from the feed point in a substantially horizontal direction. This antenna is capable of receiving FM radio broadcast waves with high gain, even if it is installed in a limited blank space around the defogger.
