PURPOSE: To provide an improved antenna on the vehicle window which is used suitably together with a mobile telephone. CONSTITUTION: This antenna is formed ideally on the vehicle window and so designed as to minimize disturbance to view through the window and provide a superior electric impedance match between the antenna and a connection coaxial cable. Further, this antenna is equipped with two close conductive members 11 and 12 which are positioned in the window and electrically connected. The 1st conductive member 11 has leg parts 15 and 16 of lengthλ/4 in a V shaped. The vertex 17 of the V shape faces the 2nd conductive member 12 which is parallel to the edge part of the window. The two conductors are electrically connected at a position 20 right facing the vertex 17 of the V shape and the vertex of a V shape on the 2nd conductor. The 2nd conductive member 12 has a length of 1/4+n/2 (n: positive integer (including 0)) on respective sides of the connection place 20.
