Abstract (en)
[origin: EP0408194A2] An antenna for mounting on the window or the like comprises outer (14) and inner RF transfer members (46), each having an electrically conductive member (17, 58) on its underside for respective engagement with the inside and outside of the window (12). A current-fed radiator (16) is carried by the RF transfer member (14) on the outside of the window, while the inner RF transfer member (46) connects to electrical cable (50) having both a main electrical conductor (52) and a ground conductor (53). In accordance with this invention, counterpoise means comprises a conductor carried by the inner RF transfer member which is adapted for electrical engagement with a ground conductor. Typically, the elongated conductor is of about a quarter wavelength and is a coil (80). The counterpoise means (80) typically extends in a direction which is at least generally in the direction of the current-fed radiator (16).
