Abstract:
Antenna arrays which can work simultaneously in various frequency bands thanks to the physical disposition of the elements which constitute them, and also the multiband behavior of some elements situated strategically in the array. The configuration of the array is described based on the juxtaposition or interleaving of various conventional mono-band arrays working in the different bands of interest. In those positions in which elements of different multiband arrays come together, a multiband antenna is employed which covers the different working frequency bands. The advantages with respect to the classic configuration of using one array for each frequency band are: saving in cost of the global radiating system and its installation (one array replaces several), and its size and visual and environmental impact are reduced in the case of base stations and repeater stations for communication systems.

Claim (Index 12):
An antenna array comprising:\n a ground plane layer; a plurality of antenna elements arranged on the ground plane layer along a longitudinal direction of the antenna array; a first distribution network configured to excite the plurality of antenna elements for a first polarization; and a second distribution network configured to excite the plurality of antenna elements for a second polarization, the first and second polarizations being orthogonal polarizations, wherein: the plurality of antenna elements are configured to provide operation of the antenna array in three frequency bands respectively associated with three cellular frequency bands; the highest frequency of a first frequency band of the three frequency bands is less than the lowest frequency of a second frequency band of the three frequency bands and the lowest frequency of a third frequency band of the three frequency bands is greater than the highest frequency of the second frequency band; a ratio between a frequency of the third frequency band and a frequency of the first frequency band being smaller than 1.5; a spacing between the antenna elements of the plurality of antenna elements is less than a wavelength of the lowest operating frequency of the first frequency band; and a spacing between the antenna elements of the plurality of antenna elements is greater than a half wavelength of the highest frequency of the third frequency band.
