Definitions

  • the invention relates to a slot radiator element according to claim 1.
  • Slot radiator elements as often used in high-frequency technology as an antenna include a longitudinally extending waveguide with at least one slot for emitting a portion of a guided in the waveguide electromagnetic wave. In the area of the slot is often one from one conductive material existing pin as means for exciting the radiation of Waveguide shaft provided from the slot. Such a slot radiator is e.g. out DE 1 959 159 U known. In the equivalent circuit diagram, this represents a first cross-connected Capacitance C1 on the waveguide.
  • the object of the invention is to provide an improved slot radiator element.
  • the coupling means by a at the with the Slit running a broadside laterally adjacent to the slot arranged pin formed and with its center over the lateral boundary arranged the bridge.
  • the slot of the waveguide is shown as a series resonant circuit, the stepped recess one to the Series resonant circuit connected in parallel negative capacity.
  • Negative and positive capacity can be explained with the help of field theory. So represents the coupling agent in the region of the slot is a positive capacity.
  • Field Theory the effect of the coupling agents can be seen as field distortion, predominantly explain the electrical field of the wire. This leads to an increase in the Field energy around the coupling agent, e.g. a pen around. In a wiring diagram this effect can be represented as capacity. Because the concentration of the electric Field is increased, the capacity is positive.
  • Substitute circuit diagram can also be displayed as a capacity.
  • stepped depression of the web the web is reduced, which is a reduction the field energy causes.
  • the capacity thus has a negative value.
  • the means for excitation the radiation of the waveguide wave by a laterally disposed next to the slot Pen formed of a conductive material is provided.
  • the pin with respect to the longitudinal direction of the waveguide in the amount of Center of the slot arranged.
  • the step-shaped recess has a rectangular cross section with a length D and a height H parallel to and / or perpendicular to the longitudinal direction of the web.
  • the step-shaped recess and the slot are advantageous with respect to the longitudinal direction of the waveguide centered to each other.
  • the width B of the web is advantageously greater than the width b of the slot.
  • Fig. 1a and 1b show fragmentary slot radiating element in the form of a rectangular ridge waveguide with two broad sides 4, 9 as well as two narrow sides 7, 8.
  • the waveguide 1 is provided with a slot 2, which is in Longitudinal direction of the waveguide 1 extends.
  • the slot 2 serves to emit a Part of an electromagnetic wave guided in the waveguide.
  • the length of the Slot 2 is half the wavelength in the illustrated embodiment ⁇ / 2 of the operating frequency, i. the resonant frequency of the slot radiator element.
  • another (second) broad side 9 is another (second) broad side 9, on the inside of the slot 2 opposite one also provided in the longitudinal direction of the waveguide 1 extending web 3 is.
  • a pin 5 is arranged from an electrically conductive material, by which means for exciting the radiation of the waveguide wave from the Slot 2 are formed.
  • the pin 5 causes an asymmetrical distortion of the field distribution in the waveguide in the region of the slot, which makes it the waveguide wave is allowed to exit from the slot 2 for radiation. Without such means to Excitation of the radiation would be a rectangular ridge waveguide of the type shown, in which both the slot 2 and the web 3 run in the center of the waveguide, do not radiate.
  • the pin 5 or generally speaking, the means for exciting the radiation of the waveguide wave from the slot 2, a capacitance C 1 , which is connected in parallel to a series resonant circuit LCR representing the slot 2.
  • the capacitance C 1 means a load of this series resonant circuit LCR with a capacitive reactance.
  • a stepped recess 6 is formed on the web 3 in the region of the slot 2.
  • This step-shaped depression 6 represents for the wave propagating in the waveguide 1 a second cross-connected capacitance C 2 which at least partially compensates for the first cross-connected capacitance C 1 represented by the pin 5.
  • the stepped recess 6 has seen from the side a rectangular shape with a length D and a height H. Viewed transversely to the longitudinal direction of the waveguide 1, the step-shaped recess 6, the width of which corresponds to the web 3, a likewise rectangular cross-section.
  • the step-shaped recess 6 thus has a resulting negative capacitance, which is the (positive) capacity of the means, ie the pin 5, for exciting the radiation from the slot 2 just opposite.
  • the means 5 for the radiation from the slot 2 forming pin 5 is with respect to the Longitudinal direction of the waveguide 1 is arranged centrally on the slot 2.
  • the bridge has 3 transverse to the longitudinal direction of the waveguide 1 seen a rectangular cross section, wherein the width B of the web 3, and thus also the step-shaped recess 6, greater than the width b of the slot 2 is.
  • the laterally arranged next to the slot 2 Pin 5 is centered about the lateral boundary of the web 3.
  • the step-shaped recess 6 is with respect to the longitudinal direction of the Waveguide 1 is arranged centrally on the slot 2.
  • the resulting effect of the combined arrangement of the means of radiation the waveguide shaft forming pin 5 and formed by the recess 6 Step form consists in an excitation of the radiation of the waveguide shaft from the Slot 2 without a load on the circuit with a capacitive reactance.
