Abstract (en)

[origin: WO9917403A1] A dual, preferably orthogonally polarized microstrip patch antenna which includes a layer of electrically insulating material in the form of a printed circuit board. First and second sets of electrically conductive patches, preferably of copper, are disposed on one surface of the electrically insulating material, the first set adapted for transmission and/or reception of electromagnetic radiations polarized in a first direction and the second set adapted for transmission and/or reception of electromagnetic radiations polarized in a second direction. Patches of the first set are interlaced with patches of the second set. A feed for each of the patches is coupled to the opposing surface of the electrically insulating material which includes a first plurality of slots, one associated with each of the patches of the first set for polarizing the patches of the first set in the first direction and a second plurality of slots, one associated with each of the patches of the second set for polarizing the patches of the second set in the second direction. The centers of the patches of the first and second sets of patches are disposed in a straight line and the centers of adjacent patches of each of the sets of patches are spaced apart less than one wavelength of the carrier frequency of interest.
