Definitions

  • the invention described herein relates to certain improvements in transmission of energy by electromagnetic waves, and has for its object the production of more efiicient conductors.
  • Figure l is a sectional elevation of aform of apparatus for the practice of my invention.
  • Fig. 2 is a top plan view of the same.
  • the conductors are in sections, which can be 1nechanically and electrically connected by the supporting-rings, as shown.
  • This conductor may be connected to ground in any suitable manner, as by the wire 8.
  • the wires forming the conductor being about equal in electrical length and being connected transversely when transverse connections are used only at equal po-- tential points, as shown, the absence of crosscnrrents in the aerial or conductor produces a higher efliciency and a better form of waves.
  • each of said electrically-parallel conductors should be of low resistance and of substantially equal electrical length;
  • any-cross connections should be between equipotential points, and, fourth, the aggregate or sum of the eflt'ective capacities per unit length of all of theparallel couduetors should be the same at all distances along the capacity area, and the simplest way to insure this is to make each of said conductors ofone uniform cross-sectional outline from end to end.
  • What I claim is- 1.
  • a conductor consisting of a number of wires so arranged and proportioned as to radiate a substantially pure sine wave.
  • a conductor consisting of a number of Wires having low resistance.
  • a conductor consisting of a number of wires having low resistance, and having large capacity.
  • a conductor consisting of a number of wires suitably spaced, so as to produce the eifect of a largecapacity area.
  • a conductor consisting of a number of regularly-spaced wires arranged so as to produce the eflfect of a large-capacity area.
  • a conductor consisting of a number of wires of equal electrical length arranged so as to produce the effect of a large-capacity area.
  • a conductor consisting of a number of wires transversely connected only at equal potential points.
  • a conductor consisting of a number of regularly-spaced wires having low resistance.
  • a conductor consisting of a number of regularly-spaced wiresand having large capacity.
  • a conductor consisting of a number of wires of equal electrical length so as to form a conductor of low resistance and large capacity.
  • a sending-conductor for transmission of energy by electromagnetic waves consisting of a number of wires so arranged and proportioned as to radiate a substantially' pure sine wave.

  • a sending-conductor for the transmission of energy by electromagnetic waves consisting of a number of wires of equal electrical length so as to form a conductor of low resistance and large capacity.
  • a low-resistance conductor grounded at its lower end only and having the major portion of its length composed of a plurality of low-resistance conductors, said latter conductors having their individual capacities approximately evenly distributed throughout their length, substantially as set forth.
  • a conductor having the major portion of its length composed of a plurality of low-resistance wires, the average distance between said wires being great as compared with their diameters, substantially as described.
  • a conductor having a large fraction of its length composed of a plurality of low-resistance conductors of substantially uniform cross-sectional outline, spaced apart laterally and extended longitudinally to form a large capacity portion, substantially as set forth.
  • a conductor for use as a radiator or collector of said energy comprising a plurality of conductors of substantially uniform crosssectional outline, spaced apart laterally, extended longitudinally and electrically connected to oscillate in parallel with each other and in series with a common ground, the length of each of said longitpdinally-extending conductors being electrically the same and equal to a large fraction of the quarterlength in the surrounding medium of a wave having a time period equal to the natural free period of said conductor, substantially as set nected with the ground at one end only, for 10 forth. the purpose set forth.
