  • Method of and means for coupling a two conductor transmission line to an antenna
    Patent number: 4644364
    Abstract: Impedance matching between two conductor transmission lines and conventional antenna designs including a straight antenna element having an effective length of at least one-quarter wavelength in the operating frequency range and a zero impedance at one end is disclosed in which a straight coupling conductor having a length of about one-quarter wavelength in the operating frequency range is mounted in close spaced co-planar relation to such antenna element with one end electrically connected to the zero impedance end of the antenna element. The two conductors of the transmission line are coupled to the antenna element and coupling conductor, respectively, at the interconnected ends thereof and the spacing between the antenna element and the coupling conductor is adjusted along their coextensive lengths to achieve an impedance match at each frequency in the operating frequency range.
