ABSTRACT:
A vehicle window antenna for receiving radio waves of a predetermined wavelength comprises an electrically conducting entity affixed to the window glass having a horizontally elongate principal element having an effective horizontal length of an odd multiple of one quarter of the predetermined wavelength and an impedance matching element having a length of a multiple of one half the predetermined wavelength, extending along but spaced from the edge of the window so as to form a slot transmission line therewith, and parasitically coupled to the principal element by a connecting element. The impedance matching element is an extended ribbon which may leave most of the viewing area of the window free. Therefore, it uses significantly less of the material from which the antenna itself is made; it may be made of non-transparent as well as transparent material; and it provides great flexibility of design, with a number of different embodiments and variations.
