Definitions

  • Each parasitic element 12 acts as a radiating element which radiates energy of the two polarisations into the vicinity of the patch assembly. This radiation, when adjusted properly, can actively cancel the unwanted cross-coupling radiation in the region, which results in high isolation between the polarisations.
  • the position, shape, length and width of each parasitic element are selected for optimal isolation at the frequencies of interest.
  • Figure 6 illustrates a simplified antenna having only one patch assembly which in structure corresponds to one of the patch assemblies 1 to 4 of Figures 1 to 4.
  • the antenna of Figure 6 is devoid of the panel 5 and the feed/reception tracks, signals being conducted to the respective areas 15, 16 by conductive cables rods or pins 26.
  • the areas 15, 16 are capacitively coupled to the main conductive area 17 on the upper surface of the lower panel 11, the lower surface of which has an arcuate parasitic element 12 subtending an angle of about 270° symmetrically arranged with respect to the areas 15 and 16.
  • the parasitic element 12 lies wholly within the volume defined between the coating area 17 and the 6, and within the plan area or "footprint" of the coating area 17.
