Abstract
An antenna for diversity operation comprising a plurality of connected antenna units (100). The antenna units each having a first radiation element (102) with length of a quarter of a wavelength at a first operating frequency a second radiation element (104) with length of a quarter of a wavelength at a second operating frequency distinct from the first operating frequency, the second radiation element sharing with the first radiation element a segment of the first radiation element. A feed point for coupling a feed to one of said first or second radiation elements such that the elements resonate at the first and second operating frequencies respectively and at substantially orthogonal polarizations. Diversity antennas configured with two or more of the antenna units.
