Claim 18:
19. An array antenna arrangement comprising:
a substrate surface; and
first and second antenna portions each including:
a parasitic patch arrangement arranged on the substrate surface;
first and second radiator arms arranged on the substrate surface, operably coupled with the parasitic patch arrangement, spaced apart by a first gap, and responsive respectively to complementary components of a first differential signal to emit a first radio frequency signal having a first polarization characteristic; and
third and fourth radiator arms arranged on the substrate surface, operably coupled with the parasitic patch arrangement, spaced apart by a second gap intersecting the first gap, and responsive respectively to complementary components of a second differential signal to emit a second radio frequency signal having a second polarization characteristic orthogonal to the first polarization characteristic;

the first radiator arm of the first antenna portion and the second radiator arm of the second antenna portion being arranged proximate to and operably coupled with each other, and being responsive to the respective complementary components of the first differential signal to emit the first radio frequency signal.
