Patent ID: 8497814

Claim:
A triple-band antenna array for cellular base stations, said antenna array operating at a first frequency band, a second frequency band, and a third frequency band, said first and second frequency bands are within a first frequency range and said third frequency band is within a second frequency range, said antenna array comprising: a first set of radiating elements for operating at at least said first frequency band wherein some radiating elements from the first set of the radiating elements operating at only said first frequency band; a second set of radiating elements for operating at at least said second frequency band wherein some radiating elements from the second set of the radiating elements operating at only said second frequency band; a third set of radiating elements for operating at only both of said third frequency band and said first frequency band; a fourth set of radiating elements for operating only at both said third frequency band and said second frequency band; at least some radiating elements of the first set of radiating elements are interlaced with at least some radiating elements of the third set of radiating elements, at least some radiating elements of the second set of radiating elements are interlaced with at least some radiating elements of the fourth set of radiating elements; and in the triple-band antenna array, a combination of said some radiating elements from the first set with all radiating elements of the third set provides operation of the triple-band antenna array at said first frequency band; a combination of said some radiating elements from the second set with all radiating elements of the fourth set provides operation of the triple-band antenna array at said second frequency band; and a combination of all radiating elements of the third set with all radiating elements of the fourth set provides operation of the triple-band antenna array at said third frequency band.
