PROBLEM TO BE SOLVED: To provide a high-frequency glass antenna for an automobile with a broad bandwidth having strong directivity on a certain direction, without influence of a metal portion of a car body even if an antenna is a glass antenna set near the metal portion of the car body. SOLUTION: The high-frequency glass antenna for the automobile is composed of an antenna line 10 set near a metal portion 6 of a car body and fed, and a non-fed wire for adjusting directivity, set near the antenna line. The antenna line 10 is connected to a feeding point 16 at one end, a straight line antenna line whose length is (λ/4)k, and a non-fed wire 12 extends in parallel with the antenna line, and is composed of a straight conductor line 12 whose length is (3λ/8) k. The length of the conductor line overlapped with the antenna line is (λ/8)k, and a distance between the conductor line and the antenna line is (λ/64)k. COPYRIGHT: (C)2006,JPO&NCIPI
