Definitions

  • the invention relates to an antenna for receiving and transmitting or transmitting electromagnetic energy.
  • An antenna with at least two half-wave dipoles is known, which are arranged side by side on an axis. All two half-wave dipoles arranged side by side (adjacent) are connected to the leads of an inductively phase-rotating circuit with a phase shift of 180 ° el., The distance of which is ⁇ / 8. The free end of one of the end half-wave dipoles is the active routing of the antenna (Karl Rothammel: "Antenna Handbook", Sofia, 1977).
  • a disadvantage of the known antenna is its low effectiveness, which consists in its insufficient amplification factor.
  • the invention has for its object to provide an antenna with an increased gain.
  • an antenna which contains n pairs of half-wave dipoles which are arranged on one axis.
  • the half-wave dipoles of each pair are over a corresponding phase-rotating current circuit with an inductive character.
  • the active lead-out of the antenna is led out from the free end of one of the end half-wave dipoles.
  • a quarter-wave dipole is arranged on the same axis on the side of the end half-wave dipole, the passive lead-out of the antenna being led out from the end of the quarter-wave dipole adjacent to the active lead-out.
  • connection between the pairs of half-wave dipoles and between the end half-wave dipoles and their corresponding quarter-wave dipoles is capacitive, the phase shift having an inductive character and the phase shift having a capacitive character being 60 to 120 ° el.
  • the advantages of the antenna according to the invention are its increased effectiveness, i. H. in the higher gain factor and in the increased utilization factor of the antenna surface.
  • 1 consists of n arranged on an axis 0-0 pairs 11, 12, ..., 1 n half-wave dipoles 21-31, 22-32, ..., 2 n -3 n .
  • the half-wave dipoles 21-31, 22-32, ..., 2 n -3 n are at their mutually facing ends to an inductively phase-rotating circuit 41, 42, ... or 4 n with a phase shift of 60 to 120 ° el. interconnected.
  • the connection 5 between the individual pairs 11, 12, ..., 1 n has a capacitive character with a phase shift of 60 to 120 ° el.
  • the connection 8 with the half-wave dipoles has a capacitive character with a phase shift of 60 to 120 ° el.
  • the free end of the first half-wave dipole 21 is the active lead-out of the antenna, which is connected to the inner conductor of a coaxial line.
  • the passive lead-out of the antenna is the adjacent end of the quarter-wave dipole 6, which is connected to the grounded external conductor of the coaxial line.
  • the leads of the antenna can also be derived from the free end of the last half-wave dipole 3 n and the adjacent end of the quarter-wave dipole 7.
  • the antenna according to FIG. 2 contains a pair 1 of half-wave dipoles 2, 3 which are connected to one another via an inductively phase-rotating circuit 4 designed as a coil with a phase shift of 60 to 120 ° el.
  • a quarter-wave dipole 6 or 7 is arranged on the axis 0-0, which is connected to the pair 1 via a capacitive connection 8 with a phase shift of 60 to 120 ° el the air gap between the quarter-wave dipoles 6, 7 and their adjacent half-wave dipoles 2, 3.
  • the active lead-out of the antenna is derived from the free end of the half-wave dipole 2 and the passive lead-out from the adjacent end of the quarter-wave dipole 6.
  • the active lead-out can also be led out from the free end of the half-wave dipole 3 and the passive lead-out from the adjacent end of the quarter-wave dipole 7.
  • antenna systems with several elements can be formed with a suitable amplitude-phase supply and coordination between the elements of the system.
  • the antenna works in receive or transmit mode. It represents a colinear series of half-wave dipoles 2, 3 with alternating capacitive and inductive phase shifts, each by 60 to 120 ° el.
  • the quarter-wave dipoles 6, 7 have the function of a coordinating element.
  • an amplification factor of 5 is used for a phase shift with an inductive and capacitive character of 90 ° el.
  • the meter wave range for frequencies from 160 MHz to 200 MHz , 7 ⁇ B for a frequency of 168 MHz with respect to the half-wave dipole 1 reached.
  • a gain factor of 4.4 ⁇ B for a frequency of 525 MHz with respect to the half-wave dipole is achieved for frequencies from 450 MHz to 540 MHz.
  • the antenna has an asymmetrical lead-out, which is a direct connection with an asymmetrical Lei tung, z. B. a coaxial line.
  • the asymmetrical line can also be connected via a coordination link.
  • the antenna can also be connected to a symmetrical line via a balancing and coordination element.
