Abstract
The present invention provides a glass antenna device for mobile communication with suitable impedance matching for two different frequency bands. In this antenna device, the ends of a substantially straight first radiation antenna pattern and a second radiation antenna pattern are coupled by a coupling pattern that is substantially perpendicular to the first and second radiation antenna patterns. The longitudinal direction of the coupling pattern is arranged substantially in parallel to the ground. The length of the first radiation antenna pattern is different from the length of the second radiation antenna pattern. A rectangular grounding pattern is arranged below this U-shaped antenna pattern. A core conductor of a coaxial cable is connected to the U-shaped antenna pattern, and a braided conductor of the coaxial cable is connected to the grounding pattern. An impedance-adjusting pattern is provided on a lateral portion of the grounding pattern.
