A glass antenna for a vehicle that has a first element elongated in a first direction, a second element elongated in a second direction, a third element including first, second and third partial elements that are each elongated in specific directions, and a fourth element elongated in the second direction but detours the second element in the second direction.

Glass antenna and window glass for vehicle

A glass antenna for a vehicle on or in a window glass including a defogger having a plurality of heater wires that run in parallel, the glass antenna includes: an antenna conductor; a first feeding portion; and a second feeding portion adjacent to the first feeding portion, wherein: the antenna conductor includes a first antenna conductor, which extends clockwise with the first feeding portion as a starting point, and a second antenna conductor, which extends counterclockwise at the outside of the first antenna conductor with the second feeding portion as a starting point; and the second antenna conductor includes a first element extending between the first antenna conductor and the defogger.

A glass antenna for a vehicle includes a first to fourth elements, a connection element and a first and second feeding portions. The first element is elongated from the first feeding portion in a first direction. The second element is elongated from the first element in a second direction. The third element includes: a first partial element which is elongated from the first element in a third direction; a second partial element which is elongated from the first partial element in a fourth direction; and a third partial element which is elongated from the second partial element. The fourth element is elongated from the second feeding portion in the second direction, and detours the second element in the second direction, on a side of the second direction to be elongated in the third direction. The connection element connects the fourth element to a defogger.

A high frequency wave glass antenna for an automobile includes an antenna conductor adapted to be disposed in or on an automobile window glass sheet, the antenna conductor being formed in such a loop shape that a portion of the loop shape is cut out by a length to dispose a discontinuity, both ends of the discontinuity or portions of the antenna conductor close to the discontinuity serving as feeding points, and a portion of the antenna conductor with the discontinuity disposed therein or a portion of the antenna conductor close to the discontinuity having a conductor width of 8.0 to 40 mm.

A plurality of heating wireshave a plurality of detoursformed therein, the heating wireshave inletsformed therein for connection with the detours, and both ends of each of the inletsand both ends of each of the detoursare connected by a pair of connection lines. When a shorter one of the shortest spacing between the paired connection linesand the shortest spacing between both ends of the inletsis called W, when the maximum width of the detoursin a horizontal direction is called W, when a received frequency has a wavelength of &#x3bb;in the air, and when the formula of {(W&#x2212;W)/2}=Lis established, the formula of L&#x2267;0.0053&#xb7;&#x3bb;is satisfied.

There are disposed first coupling conductors, which comprise a pair of coupling branch linesandconnected to the first antenna conductorand extend inward from the first antenna conductor. The coupling branch linesandhave open endsanddisposed so as to be adjacent to each other and be capacitively coupled to each other. The open endsandof the coupling branch linesandare located at closest or substantially closest portions to each other. The second antenna conductorincludes second coupling conductors, which comprise a pair of coupling branch linesandconnected the second antenna conductorand extending inward from the second antenna conductor. The coupling branch linesandhave open ends disposed so as to be adjacent to each other and be capacitively coupled to each other. The open ends of the coupling branch linesandare located at closest or substantially closest portions to each other.
