Glass antenna and method of designing the same.

摘要

A glass antenna having a defogger (130, 140) and an antenna conductor (100, 110, 120) each extending on a glass comprises a first antenna conductor element (110, 120) extending along the glass surface and a second antenna conductor element (100) which extends upward and downward along the glass surface substantially at the center of the defogger in a vehicle width direction in the region to which the defogger extends and a portion of which is coupled to a heating wire of the defogger through a direct current, wherein the first antenna conductor element (110, 120) is disposed to the defogger so that the heating wire (108) connected the second antenna conductor element (100) is coupled to the first antenna conductor element (110, 120) through capacitive coupling with a capacitance of about 40 pF or less. <IMAGE>
