Definitions

  • This invention relates to radio systems and more particularly to antenna-counterpoise systems and to transmission systems.
  • One object of this invention is to produce an undistorted radio field of maximum intensity.
  • Another object of this invention is to eliminate radiation from a transmission line and other auxiliary apparatus associated with an antenna system.
  • Still another object of this invention is to secure, in practice, an antenna directive characteristic which is the same as thecorresponding theoretical characteristic.
  • a further object of this invention is to prevent.
  • the system comprises a solid rod antenna, I
  • the parallel conducting surfaces comprising the inner surface of the tubular counterpoise and the outer surface of the coaxial outer conductor or sheath constitute a circuit having distributed constants of .such value as to prevent the establishment or production of undesired currents on the sheath outer surface, whereby the radiation or directive diagram of the antenna is not distorted by sheath radiation and. in the case of a vertical half wave-length antenna counterpoi se systern, a strong ground wave is secured. At the idly attached to the central portion of the antenna-counterpoise system.
  • Fig. 1 illustrates an embodiment of the inven tion in which the counterpoise is cylindrical or tubular
  • Fig. 1--A illustrates a cross-sectional view of the tubular countcrpoise
  • Fig. 1-13 is a schematic representation useful in explaining the invention
  • Figs. 2 and 3 illustrate systems constructed in accordance with the invention and having, respectively, a pyramidal and a square counterpoise;
  • Fig. 4 illustrates a system similar to that illustrated by Fig. 1 and associated with lightning protection means
  • Figs. Sand 6 illustrate systems for eliminating currents produced on the outer surface of a coaxial line sheath. 7
  • reference numerarl designates an antenna comprising sections having difierent diameters and which may be solid or tubular
  • reference numeral 2 designates a tubular cqunterpoisc
  • the antennacounterpoise system is connected by means of a coaxial line 3 comprising inner conductor 4 and outer conductor 5, through transformer 6 to a translation device 1 which may be either a transmitter or a receiver.
  • the structure comprising the antenna. I, the counterpoise 2 and the line 3 is supported by a pipe 8; the antenna, the counterpoise, the line and the pipe having a common vertical axis yy.
  • Reference numerals 9 designate the transmission line insulators and numeral ID denotes cylindrical insulators positioned between the counterpoise and the pipe 8.
  • numeral ll designates an insulator which is interposed between the antenna l and the counterpoise 2 and which contributes to the support of antenna l.
  • a disc-shaped or cylindrical metallic plate denoted by numeral [2 electrically connects the counterpoise 2 to the pipe.
  • the antenna l is conductively joined to the inner conductor 4 which may be solid or tubular.
  • the antenna I and the counterpoise 2 are each a quater wavelength long, and they constitute a vertical doublet half-wave system.
  • the high voltage established or existing during the transmission period between the remote .terminals of the antenna which is represented by the distributed inductance ll, distributed capacity l8 and the resistance l9, and points on the outer sheath surface, as for example, point 20, tends to establish an undesirable longitudinal current 2
  • the tubular counterpoise 2 represented by the line 22 in Fig. 1-B forms with the pipe 8 (or outer conductor 5 if the pipe be omitted) a high impedance circuit or anti-resonant circuit 23 comprising the capacity 24 and inductance 25.
  • the anti-resonant circuit prevents substantial energization by the radiating system of the outer surface of the sheath whereby current 2
  • becomes zero or negligible.
  • a directional characteristic is obtained which is similar to the theoretical antenna-counterpoise characteristic.
  • the length of the quarter wave-length antenna is slightly adjusted for the purpose of matching the antenna-counterpoise impedance to the line impedance and the length of the quarter wave-length counterpoise is varied slightly in order to secure the high impedance mentioned above.
  • the diameter and length of the tubular sleeve 28 which corresponds in a sense to the counterpoise 2, are adjusted or chosen so that the sleeve and sheath 3 form a high Q or low loss anti-resonant circuit for the surface current with the result that no appreciable undesired standing wave or longitudinal current exists on the outer sheath surface.
  • the sleeve 28 and the associated surface of the outer conductor 5 constitute a short-circuited quarter-wave transformer.
  • one or more discs or wires 29, each having a radius of a quarter wave-length may be employed, as illustrated by Fig. 6, for the purpose of eliminating the undesired longitudinal current.
  • the disc or wire functions as a radio frequency ground.
  • Each quarter wave plate or wire system 29 is preferably connected to the coaxial line at a point where the surface current is a minimum.
  • the counterpoise may have a shape other than cylindrical.
  • the counterpoise is a self-supporting pyramidal structure comprising the inclined metallic members 30 and the horizontal metallic members 3
  • the counterpoise has a square crosssection and comprises the vertical metallic members 33 and horizontal metallic members 34.
  • the apex or top of the counterpoise is connected to the extremity of the coaxial line outer conductor 5 by means of straps or connections (not shown) similar to the discs or plates 12 and I3.

  • the coaxial transformer comprises conductors 37 and 38 which are shortcircuited at their remote terminals by a strap or disc 39. Strap 39 and the outer surface of conductor 38 are directly connected to a grounded supporting pipe or metallic flag-pole 40, which encloses a portion of line 3.
  • the inner conductor 31 is directly connected to the portion of the inner conductor 4 enclosed by counterpoise 2 and through conductor 4 to the antenna l, conductor 3'!
  • the radio frequency energy sup plied by the translation device (not shown) is impressed at connections or points 4! and 42 on the input terminals of the transformer 36 and on the line conductors 4 and 5 enclosed by the counterpoise 2.
  • No energy of the operating radio frequency flows to ground because of the high impedance offered by the transformer 36 to energy of this frequency.
