Antenna glass for back window of car

Abstract

Abstract PURPOSE:To provide antenna glass having sufficient receiving sensitivity even if the antenna glass is applied for a rift-back or hatch-back type back window to be freely opened/closed and non-directivity for FM broad-casting waves by improving the pattern of antenna lines. CONSTITUTION:A glass plate 11 is provided with many heater lines 14 extended horizontally as a power supply heater 12 for removing blur due to dew condensation generated on the glass surface and bus bars 15 extended virtically in order to supply electric power to the heater line 14 group. As the basic pattern of an antenna conductor 13, a horizontal main antenna line 21 having a power supply point on the side part of the glass plate 11, an auxiliary antenna line 22 fitted close to the upper window frame of the main antenna line 21 with a prescribed distance from the main antenna line 21 so as to be extended in the horizontal direction of the glass plate 11, a phase adjusting antenna line 23 to connect the main antenna line 21 with the auxiliary line 22, and a vertical antenna line 17 are provided.
