Claim:
1. An antenna comprising: a first dipole having a first polarization, said first dipole comprising a first pair of dipole arms; a second dipole having a second polarization, said second dipole comprising a second pair of dipole arms, wherein at least one dipole arm of said first pair of dipole arms is adjacent to at least one dipole arm of said second pair of dipole arms so as to form at least one isolation slot therebetween, and currents along said at least one isolation slot being operative to at least partially cancel mutual coupling between said first dipole and said second dipole; a feed arrangement for feeding said first and second dipoles; a nonconductive stem comprising multiple conjoined legs operative to support said first and second dipoles, said feed arrangement being integrally formed with said stem; and a conductive strip operative to further cancel mutual coupling between said first and second dipoles inserted between a plurality of grooves formed on adjacent legs of said stem, wherein said conductive strip is galvanically connected to solder pads on adjacent legs of said stem operative to secure said conductive strip to the stem, and said conductive strip is capacitively coupled to and not galvanically connected to said feed arrangement and to said first and second dipoles.
