VEHICLE GLASS ANTENNA, VEHICLE WINDOW GLASS, AND VEHICLE GLASS ANTENNA FEEDING STRUCTURE

摘要

A vehicle glass antenna in which an earth portion is a region for electrically connecting a non-feeding conductor to a vehicle body and a feeding portion and the earth portion are disposed side by side along a reference direction. An antenna conductor comprises: a first element having a starting point at the feeding portion and extending in a first direction that is a direction parallel with the reference direction and pointing toward the opposite side of the earth portion; a second element connected to a first terminal portion that is an end of the first element on the opposite side from the feeding portion and extending in a second direction that is a direction orthogonal to the first element and pointing toward the inner side with respect to the outer circumference of a window glass; and a third element having a starting point at the second element and extending in a third direction that is the opposite direction to the first direction. The non-feeding conductor includes non-feeding element that is an element, at least a part of which extends in the second direction with a starting point at the earth portion.
