Patent ID: 8026858

Claim:
A glass antenna device for a vehicle, comprising: an antenna element to be installed at a glass part, the antenna element comprising: a rectangular ground part including a first part and a second part; and a radiating element comprising one side being in parallel with one side of the ground part, the radiating element being distant from the one side of the ground part by a predetermined spacing; wherein the first part of the ground part is configured to be overlapped with a conductive member; wherein the second part of the ground part includes the one side of the ground part and faces the radiating element, wherein the second part of the ground part is configured not to be overlapped with the conductive member, a longitudinal side of the radiating element being in parallel with a boundary between the first part and the second part, the longitudinal side of the radiating element extending the length of the radiating element, wherein the ground part has a rectangular shape, and the radiating element comprises a first part extending vertically from one side of the ground part and a second part extending from the first part in parallel with the one side of the ground part, wherein the second part of the radiating element comprises two resonant parts having resonant frequencies different from each other, wherein at least one of the two resonant parts comprises a narrow width part and a wide width part in a longitudinal direction, and wherein the wide width part extends beyond one end of the ground part.
