<p>A window antenna appropriate for radio communications for motor vehicles consists of a loop antenna conductor (6) and of a conducting surface (8) arranged in the marginal region of the window (1). The base (7) of the antenna conductor (6) is arranged in the immediate vicinity of the conducting surface (8, 9, 10) without being connected to it. The other end (6') of the antenna conductor (6) is in an electrically conducting link with the conducting surface (8, 9, 10). By comparison with known antenna structures for radio communications, the behaviour of this antenna structure, as far as tuning is concerned, is relatively insensitive to mechanical tolerance when mounting window antennae. <IMAGE></p> |
