Abstract: There is provided a high frequency glass antenna for automobiles which is capable of having an improved antenna gain without changing the shape of a defogger. A defogger, an antenna conductor, a feeding portion for the antenna conductor, a grounding conductor, and a grounding-side feeding portion for the grounding conductor are disposed in or on a rear window glass sheet for automobiles, the defogger forms at least one portion of the grounding conductor; and the grounding-side feeding portion is electrically connected to the defogger.

Abstract: A glass antenna for an automobile improving antenna gain is provided. The glass antenna can receive two wavelength bands, that are a first wavelength band and a second wavelength band higher than the first wavelength band, and provided that the first wavelength band is designated as H band and the second wavelength band is designated as L band, antenna conductors 6, 7 for H band each having a shape and dimension configured to receive H band is provided on a rear glass plate 10 for an automobile, and an antenna conductor 1 for L band having a shape and dimension configured to receive L band is provided on the rear window glass plate 10, the antenna conductors 6, 7 for H band and the antenna conductor 1 for L band constitute two types of antenna conductors, the antenna conductor 1 for L band has a portion extending in a predetermined direction, and provided that the portion is designated as a predetermined direction extending portion 1c, the predetermined direction extending portion 1c has a detour portion 1b.
