Abstract
The invention relates to an antenna on a vehicle rear window glass for the reception of FM radio broadcasting and TV broadcasting in both the VHF and UHF bands. The window glass is provided with defogging heater strips, and the antenna uses a space left above the heater strips. The antenna is essentially comprised of an L-shaped primary element with a vertical part on or close to the vertical center axis of the window glass and a horizontal part extending from the lower end of the vertical part, an impedance matching element located on one side of the vertical part of the primary element and an auxiliary element extending horizontally above the impedance matching element. The impedance matching element has two parallel horizontal parts, at least one vertical part connecting the two horizontal parts to each other and two extensions which extend vertically from the two horizontal parts, respectively, and bend to connect to the vertical part of the primary element. The auxiliary element is connected at one end thereof to the vertical part of the primary element directly or via a portion of the impedance matching element. The other end of the auxiliary element is connected to a feed point located near to a side edge of the window glass.
