Patent ID: 7425926

Claim:
A high frequency wave glass antenna for an automobile, comprising: two glass sheets, the glass sheets being bonded through a bonding layer to form a laminated glass sheet for an automobile; an antenna conductor; an antenna-conductor-side feeding electrode connected to the antenna conductor; the antenna conductor and the antenna-conductor-side feeding electrode being disposed between the two glass sheets; and a receiver-side feeding electrode disposed at a position to confront the antenna-conductor-side feeding electrode and on a car-interior-side surface of the laminated glass; wherein the antenna conductor is configured to receive at least one of a digital television broadcasting frequency band and a UHF television broadcasting frequency band; wherein each of the antenna-conductor-side feeding electrode and the receiver-side feeding electrode has an area of from 49 to 2,500 mm 2 ; and wherein a distance between the antennas-conductor-side feeding electrode and the receiver-side feeding electrode is set so that both electrodes form at least one of electromagnetic coupling and capacitive coupling; and wherein a received signal excited in the antenna conductor is transmitted through the antenna-conductor-side feeding electrode to the receiver-side feeding electrode.
