Title:
GLASS ANTENNA FOR AUTOMOBILE
Document Type and Number:
Japanese Patent JP3491807
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To not only perform the suitable reception of FM radio broadcasting but also receive AM radio broadcasting waves and the radio waves of a long wave band and a short wave band by a single body by effectively disposing an antenna line in a sideways S shape to a vehicle side part window glass, turning it to a glass antenna and improving direction characteristics.
SOLUTION: A power feeding part 2 is provided on the lower right part of the vehicle inner side surface of the one plate glass 1 of the vehicle side part window glass. Then, this glass antenna 3 is constituted of the first vertical line 31 of a length 320mm extended upwards along the right side of the plate glass 1 from there, the first horizontal line 32 of the length 330mm extended to a center part along an upper side, the second vertical line 33 of the length 370mm extended downwards at the center part, the second horizontal line 34 of the length 330mm extended from the lower side of the center part to a left side, the third vertical line 35 of the length 370mm extended upwards along the left side and the short horizontal line 36 of the length 100mm turned to the center part further. Screen printing is performed before the bending work of the plate glass 1 and calcination is performed simultaneously with the bending work. Thus, dip avoidance by the difference of radio wave arriving directions is made possible.
